Features

Total transformation on and off the trail starts with Rough Country's 4-Inch X-Series Suspension Lift Kit for Jeep. This all-inclusive package delivers aggressive styling, increased ground clearance, and enhanced off-road capability for the ultimate upgrade.

Precision Adjustable Control Arms: This kit includes front and rear upper and lower X-Flex Control Arms featuring a high-clearance design. Built with OEM-style rubber bushings, fully rebuildable flex joints, and massive 2.5-inch diameter bodies with 1.25-inch threads, these arms are fully greasable for long-lasting durability and superior articulation. Fine-tune your ride height and suspension geometry with ease.

Optimized Suspension Geometry: Lifted coil springs and rear coil correction plates provide the perfect combination of ride height and vibration dampening. The correction plates adjust the rear coil spring angle by 10 degrees, allowing for optimal suspension performance across any terrain.

Heavy-Duty Forged Adjustable Track Bar: Strength and stability are delivered by a 16-pound forged solid steel Adjustable Front Track Bar. This heavy-duty component outmatches stock parts, maintaining precise axle alignment and control even during extreme off-road flexing. It's fully adjustable on the vehicle and easy to install.

Custom Shock Options for Any Terrain: Select from nitrogen-charged N3 shocks, V2, M1 Monotube, or premium M1R shocks to match your driving style. From versatile daily comfort to maximum off-road control, this kit lets you tailor your suspension for any adventure.

Confident, Balanced Stance: This lift kit levels the front of your Jeep with the rear, creating a commanding, well-balanced look that performs as good as it looks.

Peace of Mind Guaranteed: Backed by Rough Country's Limited Lifetime Replacement Warranty, you can hit the trails knowing your investment is protected.

  • Easy Bolt-On Installation: Simple, no-cutting-required setup for a quick, hassle-free upgrade.
  • Increased Ground Clearance: Gain extra ride height to tackle off-road obstacles with confidence.
  • Front-to-Rear Level Stance: Levels the front of your vehicle with the rear for a balanced, aggressive profile.
  • Heavy-Duty Adjustable Front Track Bar: Constructed from forged solid steel for unmatched strength, durability, and precise axle alignment.
  • Rear Coil Correction Plates: Correct the rear coil spring angle by 10 degrees, optimizing suspension geometry and improving overall performance.
  • X-Flex Control Arms: Built for extreme flex with OEM-style rubber bushings, fully rebuildable flex joints, a massive 2.5" diameter body with 1.25" threads, and a fully greasable design for maximum durability and articulation.
  • Custom Shock Options: Select from nitrogen-charged N3 shocks, V2, M1 Monotube, or premium M1R shocks for a ride tailored to your off-road needs and preferences.

Fitment Notes:

  • Does NOT fit 2-door models.
  • 2012-2018 models require exhaust modifications to clear the front driveshaft SKU: 1030.
  • On Automatic equipped vehicles; due to use of an oversize driveshaft from the factory and inadequate factory clearance it may be possible for the front driveshaft to come in contact with the automatic transmission pan tearing the factory boot and rubbing on the shaft. Generally this occurs during heavy articulation when front sway bar links are disconnected and longer shocks are installed. If this is found to occur, the proper procedure would be to replace the oversize factory shaft with an aftermarket smaller diameter shaft to increase clearance between the transmission and front driveshaft. Rough Country does offer this driveshaft if needed.
