Built for Jeep Gladiator JT owners who want commanding ground clearance and aggressive tire capability without sacrificing daily ride quality. This 3.5-inch lift kit combines front and rear dual-rate coil springs with your choice of monotube or nitrogen-charged shocks to elevate your truck's stance while maintaining smooth, factory-like handling. Run up to 37-inch tires and conquer terrain that would stop a stock Gladiator.

What's included
- 3.5-inch Coil Spring Kit Box — Front and rear dual-rate coil springs engineered to handle your Gladiator's new ride height with progressive spring design that keeps pavement smooth and delivers control on rough terrain.
- M1R Monotube Reservoir Shock Pair (Front and Rear) — Premium nitrogen-charged shocks with monotube design for superior damping control and durability across highway cruising and rocky trail work.
Important notes
