A pair of Rock Krawler triple rate rear coil springs. The same spring is used across several Wrangler applications, and the lift height you get depends on the model, so the table below spells it out.
Rock Krawler combines three spring rates in each coil to maximize effective travel and keep the spring from unseating at full droop, and it lists the on-road ride quality as excellent.
What's included
- One pair of rear coil springs

Fitment
Rear of the Jeep Wrangler JK (4.5 inch lift) and JKU (3.5 inch lift).
Before you order
- Lift heights are based on a Rubicon with a standard build (front bumper and winch, rear bumper and full size spare).
- With a spare delete, Rock Krawler suggests dropping 1 inch in coil lift height for the rear. For an overland style or heavily up-fitted rear, it suggests going up 1 inch.
- If your JK or JKU does not already have them, Rock Krawler's JK rear coil spring correction wedges (RK02659) are needed with its springs.
