Rusty’s CJ Suspension Systems
Rusty’s CJ Suspension Kits breathe new life into one of the most iconic Jeep platforms ever built. Whether you’re restoring a classic trail rig or upgrading your weekend cruiser, our CJ leaf spring kits offer the perfect blend of ride comfort, strength, and articulation—backed by decades of off-road experience.
Rusty’s CJ kits are available in 2.5", 3", and 4" lift heights, giving you the clearance to run everything from stock-size tires up to 35s while improving off-road performance and daily drivability.
Built for Strength and Ride Quality
Rusty’s CJ-specific leaf spring packs are engineered to perform on and off the trail. Every spring pack features:
-
Bolt-style retaining clips for smooth flex and better ride control
-
Nylon anti-friction pads between each leaf to reduce wear and improve ride quality
-
Full military wrap eyes for added durability and peace of mind on the trail
We also include 6-degree steel rear axle shims to correct driveline angle—no cheap aluminum here.

American-Made Quality You Can Count On
Rusty’s has been building Jeep suspensions for over 47 years, and our CJ kits reflect that legacy. Our springs are designed, tested, and manufactured in the USA, using materials and construction techniques you can rely on in the garage or deep in the woods.
If your CJ’s suspension is worn out, underbuilt, or just ready for a new adventure, Rusty’s has the lift to get it back on track.
