4 Inch Lift Kit | X-series | M1r | Jeep Wrangler Unlimited 2wd/4wd (07-18)

Built for Jeep Wrangler Unlimited owners who want aggressive styling, increased ground clearance, and enhanced off-road capability, this 4-inch X-Series lift kit delivers a complete suspension transformation on and off the trail. You'll gain extra ride height to tackle obstacles with confidence while leveling the front of your Jeep with the rear for a balanced, commanding stance.

What's included

• Forged Adjustable Front Track Bar — A 16-pound solid steel component that maintains precise axle alignment and control during extreme off-road flexing, fully adjustable on the vehicle.
• X-Flex Control Arms (front and rear upper/lower) — High-clearance arms with OEM-style rubber bushings, fully rebuildable flex joints, 2.5-inch diameter bodies with 1.25-inch threads, and greasable design for maximum durability and articulation.
• Rear Coil Correction Plates — Correct the rear coil spring angle by 10 degrees to optimize suspension geometry and improve overall performance.
• Lifted Coil Springs — Provide the perfect combination of ride height and vibration dampening across any terrain.
• M1R Monotube Reservoir Shock Pair — Premium nitrogen-charged shocks for maximum off-road control and responsiveness.

Important notes

• Does NOT fit 2-door Wrangler models — Unlimited (4-door) only.
• 2012–2018 models require exhaust modifications to clear the front driveshaft (Rough Country SKU 1030).
• On automatic-equipped vehicles, the factory oversize driveshaft may contact the transmission pan during heavy articulation when the front sway bar links are disconnected and longer shocks are installed. If contact occurs, replace the factory driveshaft with an aftermarket smaller-diameter shaft. Rough Country offers this driveshaft if needed.
