4.5" Extreme-Duty Suspension System
Rubicon Extreme-Duty spring-under kits are favorites among the
classic die hard Jeeper. These are similar to the YJ kit yet include
extra hardware, allowing the use of 2.5" wide springs up front.
Whether you are out running tight technical trails, or just cruising the back country with the family, this is the best suspension
system money can buy for a CJ.

The venerable CJ is the heart and soul of the modern Jeep. Although these vehicles are beginning to
become classics, they still offer a solid platform to build a real world off-road performer. We have two
types of suspension available for the CJ: spring-over axle or spring-under axle designs. Both offer distinct qualities and the buyer should understand the advantages of each before making a decision.
Spring-under: Stays with the stock design of leaf packs under the axle. Both 2.5-inches and 4.5-inches lift heights are
available in a complete bolt on package. Highlights of the kit are features like greaseable shackles and bushings, ExtremeDuty springs for smooth ride and long lasting service life, great all around handling, great load capacity, and built in conversion to 2.5-inches wide springs for added strength and interchangeability with YJ Wrangler springs. This easy to install package will amaze you with the increase in wheel travel and stability on the trail.
Spring-over:
By relocating the stock springs on top of the axles 5.5-inches of lift is generally obtained. One can also
achieve more lift by using our 1.5-inch lift SOA leafs for a total of 7-inches of suspension lift. In order to perform this conversion you will need to do the following: Weld new spring pads to axles, extend brake lines, weld on new shock mounts, install
longer shocks, install drop pitman arm, install CV style rear drive-shaft and install new u-bolts and possibly new spring plates.
The potential wheel travel of a spring-over conversion is unmatched as is under axle clearance for rocks, mud and snow.
Disadvantages are higher center of gravity and greater tendency for axle wrap. Installation does require welding. See below
for a sampling of Spring-over parts that you might need to complete the conversion. Call for assistance building a custom kit
for your application.
No matter what your CJ suspension needs are, we can help you mix and match parts to get the ultimate combination for your application.
