Rock Ready 4 in. Rear Spring for Jeep Wrangler (1987-1995)

About this part

Rock Ready 4 in. Rear Spring, fitment-checked

Rear Rock Ready spring for the 1987-1995 Wrangler at 4 in. of lift, sold one to a box at 38 lb. It is 2 lb heavier boxed than the front part number, which is the usual story on a leaf-sprung Jeep: the rear pack carries the load rather than the engine, so it is built to a different rate and a different arc.

This is the rear pack in Skyjacker's Rock Ready set for the 1987-1995 Wrangler, rated at 4 in. Rear springs on a YJ take a set faster than the fronts because that is where the weight goes — a loaded tub, a spare, a bumper and a swing-out will all flatten the arc over time, and a flat rear pack is what makes an old Jeep look nose-high and ride badly. Replacing both sides at once is the only way to keep the axle square. One spring per box, 38 lb shipping weight.
