Are you tired of leaf springs? Our exclusive bolt on long arm design is now available with 4-Link Rear long arms for your XJ as an upgrade to your existing lift kit. In addition to the new long arms, you'll get 2 new subframes a rear axle truss and axle brackets which will be used to eliminate the leaf springs. This is a fully adjustable double triangulated kit that will correct your rear suspension geometry. Just like our popular front Critical Path long arms, you'll have the ability to install the subframes with NO welding, cutting or grinding at all! You'll only drill holes for the BOLT ON subframe that is brake formed from 1/4" and 7 gauge steel plate. The only welding required for this is to the rear axle!
This upgrade will allow as much articulation as your rear shocks will allow! We use a high quality greasable, pivoting flex joint on the axle side for great flexibility and factory style rubber bushings on the chassis end to absorb road "noise." Oh yes, you will need coil spring retainers for the rear now too! They are also included in the kit.
PLEASE NOTE: Purchasing coil springs and exhaust modification will be required to run this upgrade. Additionally, your XJ must have 4" or taller suspension lift.
The JK Dana 44 rear axle truss will NOT work on the XJ Dana 44 axle. XJ Dana 44 owners would
be best to start with our Dana 35 axle truss and do some cutting and grinding to
make it fit.
