We know your springs are falling out on the trail. Its a common issue in lifted WJs but we finally have solved it with no straps or harnesses. Heres our solution: 5" cones bolted to the upper spring mount. If your spring does become unseated in high articulation circumstances, the cone shaped retainers guide them back to exactly where they belong. The cones are injection molded from UV stable ABS-PC for extreme durability (PC stands for polycarbonate). Comes with mounting hardware. Coil spring isolators sold separately.
