Build your Jeep suspension.

Choose your Jeep model, door count and year to find the frame-side system. Then check your axle, steering and fuel tank layout against that kit. Two-door JK and four-door JKU builds use different kits, and the Gladiator has two front crossmember configurations.

Use Full Width Axle Kits to adapt a CJ or YJ to a compatible donor front axle. For a rear wheelbase stretch on leaf springs, use Wheelbase Stretch Kits. For a perch, hanger, shackle or bushing, go directly to Leaf Spring Parts.

For an axle bracket, measure the outside diameter of the tube where the bracket will sit. For a link or shock mount, measure the joint or eyelet width with its spacers fitted and confirm the bolt diameter. Match all three to the selected part.

Read the included-parts list for the exact SKU. A bracket and skid system provides the mounting structure. Depending on the build, you may also need links and joints, axle-side brackets, shocks, a different fuel tank or exhaust work. Product instructions identify the welding and fabrication required.
