PARTS IS PARTS RIDE MARRYING STANCE AND PERFORMANCE WITH ART MORRISON ENTERPRISES 122 By Curt Iseli O ne advantage of hot rodding in modern times is that aesthetics and performance can be combined in ways that weren’t even considered in the early days. It’s not that it wasn’t possible for a car to handle power in the curves as ably as in a straight line, or to sit low and not rattle teeth with every crack in the asphalt. It’s just that very few had figured out how. In the early-’70s Pacific Northwest hot rodder Art Morrison began building race-bred suspensions that performed well and even set some records at the strip. In the ensuing decades, he applied what he learned to hot rods and street cars, and with the help of his son, Craig, propelled Art Morrison Enterprises (AME) to the forefront of vintage automotive suspension design. From front and rear frame clips to fully customized chassis, they’ve helped redefine the handling qualities and low-slung looks that are achievable with vintage cars. The essence of the retro rod and custom movement lies in improving performance within the constructs of a traditional aesthetic. That’s a tall order when it comes to early (pre-’35) hot rods. All the mechanicals are out in the open, and although we want our cars to perform, we’re still a dropped I-beam and buggy spring kind of crowd. But cars from the fat fendered era forward are different animals. There’s a lot more sheet metal hiding those mechanicals in the curvaceous lines of the mid-’30s through the starched edges of the ’60s. And when such a car is sitting just right—raked over big-and-littles or hovering dead level inches from terra firma—no one’s going to miss bulky factory axles, A-arms and parallel leafs. This is where AME carved their niche, providing suspensions and chassis that far outperform the archaic equipment they replace. Today there are thousands of Morrison-equipped cars on the road. They’re being built by hobbyists and professional shops alike—places like Rad Rides by Troy, Alloway’s Hot Rod Shop, Oklahoma’s Hot Rod Garage and Johnson’s Hot Rod Shop. Whether the end goal is a Resto-Mod autocross terror or a simple mild custom with a killer stance, it’s been our experience that AME’s components simply make driving these old cars a whole lot more fun. WHEELSTANDER FROM WASHINGTON Given that Art’s built a career on refining vintage car handling, it’s ironic that he spent his youth piloting rowdy hot rods, Gassers and wheelstanders. Growing up in Milton, Washington, just south of Seattle, a nailhead-powered Model A and a low 12-second ’54 Chevy Gasser occupied his youth. Working out of his parents’ garage, he learned everything he needed building and Art Morrison has spent decades developing chassis and components that allow rodders to achieve killer performance and looks that match. Offerings range from bolt-on chassis to virtual U-fab kits, and their “Builders Platform” is particularly popular with professionals and advanced hobbyists who want a Morrison foundation with flexibility to position things like engine and body mounts wherever they want. Such a chassis lies under Bobby Alloway’s ’51 Chevy, and above is a baremetal example, custom-made for a mid-’50s Ford. Extensive experience and state-of-the-art equipment allows AME to build chassis for anything on four wheels. 123 PARTS IS PARTS For hobbyists whose skill or equipment limits how much fabrication they can do, Morrison offers the GT Sport line. They’re bolt-on chassis that can be ordered with a variety of front and rear suspension configurations and driveline mounts for many popular makes, from tri-five Chevys to GM A-bodies. Shown here is the ’49-’54 Chevy chassis with IFS, power rack and pinion steering, and a triangulated four-bar and 9-inch rearend housing. fixing his own cars while fabricating and selling headers on the side. He served in Vietnam for a year in ’68, then returned to Washington where his fabrication work turned into a fulltime business. One early customer was Chuck Poole, who introduced Art to a short career building and driving his famous “Chuckwagon” wheelstanders (Art also drove Richard Schroeder’s “Wentworth & Irwin” AMX). There are more stories from this era than we can possibly fit here, so we’ll save them for a future article. Suffice it to say that it was a wild time that came to a dramatic end when Art was nearly killed in an accident at Puyallup Dragway in June of ’71. “I was beat up unmercifully,” he says, “and I figured there’s got to be a better way to make a living.” There was, and he found it in early 1972 when he installed a complete rear suspension in a Modified Production ’66 Corvette. “He went out and set an A/MP record. Then all of a sudden other guys were wanting work done.” Art Morrison Enterprises was hitting its stride, and for the next 15 years suspensions and racecars—from door slammers to Alcohol Dragsters—were the focus. In 1977 he bought a one-acre compound in Fife, Washington, where AME still stands today. Business continued expanding over the next decade, but by 1990 the racing world was changing and Art decided to re-focus his efforts on hot rods. 124 THE CHASSIS FACTORY Art’s always understood that investing in equipment and technology is key, so his first order of business was improving AME’s bending capabilities. “We had our first bender modified to handle bigger 2x4-inch rectangular tube,” he says. “That gave us more credibility with street rodders.” The bulk of their catalog was focused on front and rear frame stubs and custom chassis, which are still staples of the business. Today front and rear clips are CAD-engineered to customer specs for a wide variety of applications. They’re based on artful, mandrel-bent and welded 2x4-inch .120-wall rectangular tubing. Front subframes are available with a few different suspension options, including AME’s IFS with standard control arms and coil overs, air bags or struts, as well as Sport packages boasting suspension geometry and beefier materials designed for more aggressive “track day” driving. Standard and Sport level Corvette C6-style subframes are also available, but only for later-year muscle cars or incorporated into AME’s Corvette chassis and custom packages. There are even more options for rear suspensions, ranging from parallel and triangulated 4-bars for the street (with coil overs or air bags) to more aggressive 3-link, 4-link and ladder bar clips for Pro Street and road racers. In addition to their subframes, all suspension components are available individually PARTS IS PARTS One of the most recent additions to AME’s line of bolt-on chassis is their ’59-’64 Chevy package. Here’s the Impala that was the starting point for that package. Using 3D scanners, Morrison scanned the entire body inside and out to determine all necessary dimensions and support points on which they would base their off-the-shelf custom chassis. This is the first kit that’s available with either coil over or air bag suspension. or in weld-in kits and “bikini clips” that allow further customization by the builder. One exception is AME’s Multilink IRS, which debuted in 2014. Drawing from designs found under modern sports cars like Ferraris and Porsches, the Morrison team engineered an IRS that’s as agile as it is stout, and that can be easily adapted to a wide range of applications. At the other end of the spectrum from the component and weld-in kits are AME’s complete chassis. They fall into two basic categories: the “Builders Platform” and the bolt-on “GT Sport” packages. The builder’s series is just that: a bare frame designed to the customer’s specifications incorporating any of AME’s front and rear suspensions. The possibilities here are endless, from the size of the main frame rails (2x3 inches up to monstrous 4x4 inches for bigger cars and convertibles) down to details like whether to use polyurethane-bushed rod ends or spherical bearings. It all just depends on how the car will be driven. 125 PARTS IS PARTS The 3D laser scanner relies on points placed on all surfaces of the subject being scanned to create a dimensional computerized model AME can then work from. As you may have guessed from this chopped F-100 cab, ’53-’56 Ford truck chassis are next up in their bolt-on line (as well as ’55-’59 Chevy trucks, which surprisingly share key dimensions with the Fords). They currently offer a GT Sport chassis for ’47-’53 Chevy pickups as well. Builder’s chassis come without body, bumper, engine and transmission mounts or a core support. It would be impossible to locate those items without the body in AME’s shop, and even then it’s a safe bet any builder requiring a custom chassis will want to control just where everything’s placed, from the engine setback to the body itself. We’ve featured a number of cars based on these custom chassis, like Mike Young’s LimeWorks-built ’48 Buick (TRJ #61), and we’ve recently spoken with a few builders who use this platform regularly. Bobby Alloway’s been working with Art Morrison ever since Boyd Coddington introduced them about 15 years ago. “The first one we did with Morrison was a ’56 Ford,” Bobby says. “Now just about every car we build, other than the real early stuff, has one of their frames or clips under it. I’ve probably got 10 of them in my shop now.” He begins by setting up the body with the wheels and tires he wants to use. From there he specifies key body points from the ground up, then lets AME get to work. “With their chassis I can get the look I want and it takes the guess work out of it,” Bobby says. “And the stuff they’re doing drives great going down the road.” That type of collaboration exists whether you’re building a mild cruiser or something radical like John Groendyke’s roadracing ’49 Cadillac sedanette, built by Jim and Jason Smith’s Hot Rod Garage in Oklahoma. It’s raced at Pikes Peak and La Carrera Panamericana multiple times, participated in the threeday Chihuahua Express Mexican road rally, and won the hot rod class in Goodguys’ Columbus autocross—all on a custom AME chassis. “They do a great job building a dual-purpose chassis that’s comfortable cruising and impressive at the track,” says Jason Smith. “And although we had a lot of their race-grade stuff—brakes and shocks and the 3-link rear—the basic chassis is similar to what you get with their bolt-on kits.” Those bolt-on kits were introduced in the spring of 2003, and they were the brainchild of Art’s son, Craig. He came on board full-time in December of 2000, and the next summer he spent several straight weeks on the road working AME’s booth at 126 car shows and talking to customers. “Everyone kept asking why we didn’t offer any bolt-on chassis,” he says. “It became glaringly obvious that we needed to do something along those lines.” Combing through their order history they determined the ’55-’57 Chevy was the most common platform, so Craig pulled together a business plan and presented it to Art. One year and countless hours of R&D later, the first Tri-Five “GT Sport” frame debuted. As a completely bolt-on application, it allowed hobbyists with a modest amount of skill and equipment to install a custom chassis in their home garage. “I think we sold 20 of them that first year,” Art says. “Then 50 the next, 90 after that, and now 12 years later we’ve sold almost 1,300. And there’s still a backlog of orders.” Their popularity has led to a steadily growing catalog of bolt-on offerings. Today you can slide a brand new chassis under ’49-’54 Chevy cars, ’47-’53 Chevy trucks, ’53-’62 Corvettes and ’64-’71 GM A-bodies—including El Caminos. Most recently a ’59-’64 Chevy chassis was added to the mix, available with either coil overs for a static-height cruiser or air bags for a slammed custom. Chassis for ’55-’59 Chevy and ’53-’56 Ford pickups on deck now and slated for release next year. HIGH-TECH HOT RODDING Two aspects of AME we haven’t delved into are their commitment to the quality of the workmanship and the amazing technology they use every day. About 15 years ago, our booth at the NSRA Nationals was situated catty-corner from AME’s. We wandered over to introduce ourselves and take a look at their products, and the first thing we noticed were the immaculate welds. Obviously weld quality is paramount in all automotive fabrication, but these aren’t the types of welds you’d want to skim with filler prior to paint because they’re as artful as they are functional. AME takes great pride in this level of craftsmanship, and they’re even working with a third party on a welding certification program designed specifically for the work AME does. PARTS IS PARTS A look inside AME’s manufacturing plant shows frames waiting for their final quality control check prior to being shipped. The frames in the foreground are bound for Kugel Komponents, who orders Builders Platform kits to equip with their own front and rear suspensions. Below, the fixture in the background is the jig for the new ’59-’64 Chevy and the one in the foreground is for the ’49-’54 Chevy. 127 PARTS IS PARTS The company’s commitment to investing in technology is apparent throughout their operation. Four different CNC machines—two mills and two twin-spindle lathes—“allow us to do anything we want in-house, from making parts to creating phenomenal tooling for our fabricators to use,” says Craig. The aforementioned mandrel benders handle everything from the 7/8-inch O.D. upper control arms to 2x4-inch .180-wall rectangular tubing for heavier chassis. And then there’s the testing equipment, like a Tinius Olsen machine that can apply up to 60,000lbs. of force to things like rod ends, or the custom-built dyno for testing different racks and pinions. But most fascinating, perhaps because they’re relatively new tools in traditional hot rod fabrication, are the 3D laser scanner and coordinate measuring machine (CMM, called a FaroArm) Morrison uses to plan their chassis. These hand-held devices can scan any threedimensional object—including complete bodies— to determine every contour and plot each mounting hole. They allow AME to digitize entire car bodies—sometimes without even having them on the shop floor. “It becomes this incredible packaging application,” Art says. “You can set up different front and rear suspensions, set different engines in place and design a complete chassis on the computer screen.” It’s just one more way to streamline the design and engineering process, easing fabrication of full custom frames and allowing AME to make even more popular chassis available (like those Ford and Chevy pickups). Just as it would be impossible to tell the entirety of Art’s storied past in this space, it would be futile to try to explain all the intricate details, options and parts AME manufactures and offers for our applications. These are the broad strokes of the major components, but we encourage you to do a little exploring on their website. There’s a wealth of information within that could be very helpful in your quest to improve ride quality and ring even more fun out of your next rod or custom project.

Their new rearend jig (top) is a case in point. It’s beautifully designed, incredibly intricate and no doubt required more time to design and construct than many components. Heavy-duty tubing benders (middle) have been modified to handle the large, thick-wall rectangular tubing necessary for AME’s chassis construction. Nine-inch Ford type housings (bottom) are a mainstay of Art Morrison offerings. Smooth hot-rod type housings as well as full back-braced units are available.
