Jeep YJ Wrangler Suspension Systems
Rusty’s Off Road has been building Jeep suspension systems for decades, and our YJ kits are a perfect example of that experience. Whether you're running 33s or building a flexy Spring-Over-Axle rig on 35s and up, we've got the setup to fit your needs and your budget.
From 4" leaf spring kits to full SOA conversions, every Rusty’s system is designed for real-world off-road performance with comfortable street manners. Built in the USA and packed with smart upgrades, these kits deliver the strength and ride quality Jeep owners demand.
4-Inch YJ Kits
A great all-around option for clearing 33s, Rusty’s 4" kits include custom 5-leaf spring packs with anti-friction pads and military wraps for flex and durability. Rubber bushings at the frame and poly at the shackles give you the right blend of comfort and control.
-
Standard Kit includes springs, Hydro shocks, brake line extensions, axle shims, and track bar brackets.
-
Advanced Kit adds sway bar quick-disconnects, stainless steel brake lines, a transfer case drop, and more.
Spring-Over-Axle (SOA) Kits
Rusty’s SOA kits move your springs above the axles for up to 7" of lift, more flex, and a smoother ride. Our SOA-specific leaf springs feature reverse eyes, tapered leaves, bolt-style clips, and anti-wrap tuning. Kits include anti-wrap perches, stainless brake lines, U-bolts, and more.
Welding is required, and we recommend a Slip Yoke Eliminator and CV driveshaft to correct driveline angles.
Also available: a basic SOA conversion kit if you already have springs.
Why Rusty’s?
From quality components like steel shims and stainless lines to smart upgrades like sway bar disconnects, Rusty’s kits are built with attention to detail and trail-tested reliability. Whether you’re restoring a YJ or building a dedicated wheeler, trust Rusty’s to get it right.
