Description

91240 | Rough Country 6 Inch Lift Kit with M1 Monotube Shocks Jeep Gladiator JT 4WD (2020-2023)

Take Your Gladiator to New Heights: Transform your Jeep Gladiator into an off-road powerhouse with Rough Country's 6-Inch Suspension Lift Kit. This performance-driven upgrade delivers the clearance needed to fit up to 37-inch tires, giving your ride a bold stance and aggressive look, all while maintaining a smooth, factory-like ride quality.

Engineered for Ride Quality and Capability: This all-in-one kit includes front and rear progressive-rate coil springs designed to boost ground clearance and absorb rugged terrain with ease. The included control arm drop brackets optimize suspension geometry, keeping your factory arms at proper operating angles for enhanced stability and handling.

Maximum Flex On Demand: Tackle tough trails with confidence using the quick-disconnect front sway bar links, allowing for maximum articulation when you need it most and quick reconnection for highway comfort.

Strength Where It Counts: A high-strength front CV driveshaft is included to handle the added lift while maintaining proper alignment. This driveshaft delivers improved durability and twice the strength of stock, making it ideal for hardcore wheeling.

Custom Shock Options for Your Style: This kit comes standard with nitrogen-charged N3 shocks, featuring 10-stage variable valving, a robust 54mm body, and an 18mm spring-loaded piston rod. You can also upgrade to M1 monotube shocks for greater performance and heat dissipation on demanding terrain, or go all-in with M1R remote reservoir shocks for maximum cooling capacity and consistent damping in the most extreme off-road conditions.

Backed with Confidence: Like all Rough Country products, this kit is protected by a Limited Lifetime Warranty, giving you peace of mind for the long haul.

  • Boosts Ground Clearance: Conquer challenging terrain with increased ride height for better off-road capability.
  • Compatible with All Gladiator Models: Fits both Rubicon and non-Rubicon trims without modification.
  • Upgraded Front Driveshaft Included: Maintains optimal driveline angles and durability under lift conditions.
  • Progressive-Rate Coil Springs: Delivers a smooth, stable ride on and off the trail.
