What's included
- 3.5in Coil Spring Kit Box — all fasteners, brackets, and hardware needed for secure installation to your Gladiator's frame.
- 3.5in FR Dual Rate Coil Springs — front progressive springs engineered to keep your front end planted during highway driving and off-road abuse.
- 3.5in RR Dual Rate Coil Springs — rear progressive springs matched to your new ride height for level stance and balanced suspension geometry.
Important notes
- Does NOT fit 2020–2023 Gladiator JT models equipped with the 3.0L EcoDiesel V6 engine due to motor-weight variance.
- Does NOT fit Mojave trim models equipped with FOX 2.5 shocks, which use a larger shock bolt incompatible with replacement shocks.
- This kit clears up to 37-inch tires; Rough Country recommends running 33.0–35.0 inch tires for optimal suspension geometry and ride quality.
