Built for Jeep Gladiator JT owners who want a leveled stance and tire clearance without sacrificing ride quality, this 3.5-inch lift kit combines bolt-on simplicity with forged steel geometry correction. It clears up to 37-inch tires and eliminates factory rake for a balanced, aggressive look front to back.

What's included

  • Track Bar, Forged Front (2.5–6 Inch Lift) — A massive 1.25-inch outside diameter solid steel bar with OEM-style rubber bushings keeps your axles perfectly centered and maintains factory ride quality while handling the extra lift.
  • 3.5-inch Lift Kit Box — Spacer-based lift components engineered for your Gladiator JT.
  • M1 Monotube Shock Pair (Qty. 2) — Monotube shocks tuned for the lift geometry, providing responsive damping and consistent performance on and off road.

Important notes

  • Does not fit Mojave models equipped with FOX 2.5 shocks — the larger shock bolt is incompatible with Rough Country replacement shocks.

Why customers pick this at Road Runner

  • Corrected caster and axle geometry — the forged track bar ensures your Gladiator handles straight and true after the lift.
  • Rough Country lifetime warranty backed by local service — if anything fails, we stand behind it.
  • Professionally installed by technicians who do these every week — bolt-on design means no cutting or welding.
  • Alignment performed in-house as part of every lift install — your truck leaves here dialed in.
  • Up to 37-inch tire clearance unlocked — maximize your aggressive stance and off-road capability.
