Product Description

The Artec JK4425 is a pair of rear coil spring perches and retainers built for the 2007-2018 Jeep Wrangler JK, designed to precisely relocate the factory rear coil springs when the axle has been modified - most notably as the perfect complement to Artec's own JK Rear Axle Truss, though it works with any rear axle needing corrected coil spring angle for a lift.

Each perch is CNC laser cut and bent from 1/4" steel and is fully clockable to any angle, giving builders the flexibility to dial in the correct spring angle for larger lift heights rather than being locked into one fixed position. A larger front side with a laser-etched guide also allows the spring to be located 1" forward of stock, enabling a wheelbase stretch for those pursuing that specific build goal.

The complete kit ships with bottom perches, tubing spacers, flat tube caps, spring retainers, and all necessary 1/2" hardware for both sides of the axle - everything needed for a measure-free installation when paired with a compatible Artec truss. Because installation requires welding and precise placement, this is best handled by an experienced welder or fabricator rather than attempted as a casual DIY swap, and per Artec, it's intended for off-road use only.
