Built for Jeep Wrangler Unlimited owners who want serious ground clearance without sacrificing on-road manners — this 3.5-inch lift kit levels your front end to match the rear, delivering a factory-quality stance while opening up tire options up to 35 inches. Bolt-on installation, forged steel track bars, and OEM-tuned coil springs keep your geometry dialed in for smooth handling on and off the trail.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

  • 3.5" Stage 1 Arm Drop Kit Box — control arm drop brackets that retain proper suspension angles and maintain axle alignment under load.
  • 3.5" Coil Springs (pair) — OEM-rate linear coils engineered for balanced handling, smooth ride quality, and consistent load support on rough terrain.
  • M1 Monotube Shock Pair (2) — nitrogen-charged monotube shocks with advanced damping control for responsive performance in flex and on pavement.
  • Forged Steel Track Bar with Rear Track Bar Bracket — 1.25-inch outer diameter bars with OEM-style rubber bushings ensure precise axle centering and maximum durability.

Important notes

  • Fits 4-door Wrangler Unlimited models only — does not fit 2-door JL.
  • Not compatible with 3.0L EcoDiesel V6 — engine weight variances affect coil spring rate tuning.
  • Not compatible with Rubicon, 392, or 4xe models — these variants require different coil spring rates.
  • An aftermatched aftermarket driveshaft is highly recommended. The factory driveshaft will sustain damage if suspension reaches full droop or flex. Rough Country's Jeep JL Front CV Driveshaft (SKU 5090.1A) is the approved upgrade.

Why customers pick this at Road Runner

  • Professional installation by technicians who service Jeep lifts every week — bolt-on design means same-day turnaround.
  • Alignment performed in-house as part of every lift install — geometry correction keeps your Jeep tracking straight.
  • Rough Country lifetime warranty backed locally — any warranty claim handled right here.
  • Track bar and geometry engineered to keep axle centered under load — no wandering on pavement, no binding at full flex off-road.
