Triple Rate Rear Coil Springs Engineered for Off-Road Performance on the Jeep Gladiator JT
The Rock Krawler RKRRK07328P delivers 3.0 inches of rear lift through a precision-engineered triple rate coil spring design for the 2019 to 2026 Jeep Gladiator JT.

Frequently Asked Questions
What is the RKRRK07328P?The Rock Krawler RKRRK07328P is a pair of triple rate rear coil springs providing 3.0 inches of lift for the 2019 to 2026 Jeep Gladiator JT. They use a three-spring-rate design for comfortable on-road performance and maximum articulation off-road.
What does triple rate mean on Rock Krawler coil springs?Triple rate means the spring uses three progressive spring rates that activate at different compression levels. This allows the spring to be soft enough for street comfort at low compression, firm enough for trail use at moderate compression, and stiff enough to prevent coil bind or unseating at maximum droop.
Do the RKRRK07328P springs work on all Jeep Gladiator JT trims including Rubicon and Mojave?The RKRRK07328P is designed for the Gladiator JT platform across trims, but Rock Krawler notes that lift heights are based on Rubicon-style build configurations including front and rear steel bumpers and a full-size spare. Lighter builds may see slightly more lift than stated.
Can I run the RKRRK07328P rear springs without replacing the front springs?Running rear lift springs without matching front springs will create a nose-down rake. Rock Krawler designs their coil springs as part of coordinated front and rear lift systems for proper vehicle geometry. Consult Rock Krawler for the correct front spring pairing for your Gladiator build.
What shock length is required with the RKRRK07328P 3.0 inch rear coil?Rock Krawler recommends using matched-length shocks designed for the lifted height to prevent coil unseating and ensure the spring stays seated correctly at full droop. Consult the Rock Krawler JT suspension guide for compatible shock specifications.
Are the RKRRK07328P springs compatible with the Jeep Gladiator Overland and Sport trims?Yes. The RKRRK07328P is designed for the full Jeep Gladiator JT lineup including Sport, Overland, Rubicon, and Mojave trim levels that share the same rear coil spring perch dimensions.
Do I need a professional alignment after installing the RKRRK07328P rear coil springs?A professional alignment is strongly recommended after any suspension lift installation to correct camber, caster, and toe settings for safe on-road handling and to prevent tire wear.
How long do Rock Krawler coil springs last?Rock Krawler coil springs are backed by a lifetime warranty against defects in materials and workmanship. Under normal use, properly installed springs should maintain their rated lift height without significant settling over the life of the vehicle.
Installation Instructions
- Safely lift and support the rear of the Jeep Gladiator on jack stands with the axle hanging freely.
- Support the rear axle with a floor jack and remove the rear shock absorbers.
- Carefully lower the axle to allow the factory rear coil springs to be removed.
- Remove the OEM rear coil springs and any factory isolators.
- Install the Rock Krawler RKRRK07328P triple rate coil springs, verifying the springs seat correctly in the upper and lower coil buckets.
- Raise the axle and reinstall the rear shocks.
- Lower the vehicle and verify ride height.
- Perform a professional four-wheel alignment before returning to road use.
Coilover Springs
Coilover springs are the replaceable compression springs that wrap around the shock body in a coilover assembly, determining ride height, spring rate, and the balance between comfort and handling stiffness. Swapping springs is the most direct way to tune a coilover setup for a new application without buying an entirely new system.Popular UpgradesLinear-rate springs in the 6 to 12 kg/mm range are the most popular choice for street performance and track day builds where predictable handling is more important than maximum compliance. Progressive-rate springs that soften on small bumps and stiffen under load are preferred for street cars that need to be both comfortable on rough roads and controlled in hard cornering. ID60 and ID65 springs are the most common inner diameter specifications across popular coilover platforms.What is the difference between linear and progressive coilover springs?A linear spring has a constant rate from full droop to full compression, providing consistent an...
