Clayton Off Road Adjustable Rear Track Bar for 2007-2018 Jeep Wrangler JK

Is This for You?

• You've lifted your JK 2–5" and the rear axle has shifted laterally off-center — you need an adjustable rear track bar to re-center the axle under the vehicle — this adjustable rear track bar is designed for 2–5" of lift and allows you to set the exact length needed to re-center the rear axle, correcting the lateral offset that factory-length track bars cause on lifted builds.
• You need a rear track bar with a differential cover clearance bend for maximum compatibility with the JK rear axle — this track bar includes a differential cover clearance bend that provides clearance around the JK rear differential cover, ensuring proper fitment without contact at any suspension travel position.
• You want a bolt-in track bar with forged GIIRO joints, 1-3/8" x 5/16" DOM tubing, and a lifetime warranty — made in the USA — installs using OEM bolts with no cutting or drilling required. The forged GIIRO adjuster provides maintenance-free, dual-durometer NVH isolation while allowing full articulation. Lifetime warranty. Made in the USA. For the JL rear track bar, see COR-4509110. For the JT rear track bar, see COR-4510120.

The Result

• Adjustable rear track bar for 2–5" of lift — 1-3/8" x 5/16" DOM tubing, differential cover clearance bend, forged GIIRO adjuster. Re-centers the rear axle after lift and provides differential cover clearance on the JK rear axle.
• Forged GIIRO dual-durometer bushing adjuster — maintenance-free, NVH-isolating, self-centering. Bolt-in installation using OEM bolts — no cutting or drilling required.
• Lifetime warranty. Made in the USA. Compatible with OEM and aftermarket lift kits within the 2–5" adjustment range.

The COR-4508110 is Clayton Off Road's adjustable rear track bar for the 2007–2018 Jeep Wrangler JK. When the JK is lifted, the factory rear track bar — a fixed-length bar — pulls the rear axle laterally off-center toward the driver side, causing uneven tire clearance, steering pull, and handling imbalance. This adjustable track bar corrects the lateral offset by allowing the bar length to be set precisely for the installed lift height, re-centering the rear axle under the vehicle. The bar is constructed from 1-3/8" x 5/16" DOM tubing and includes a differential cover clearance bend that provides clearance around the JK rear differential cover at all suspension travel positions. The adjuster uses a forged GIIRO dual-durometer bushing — maintenance-free, NVH-isolating, and self-centering. Installs using OEM bolts with no cutting or drilling required. Designed for 2–5" of lift. Lifetime warranty. Made in the USA. For the JL rear adjustable track bar, see COR-4509110. For the JT rear adjustable track bar, see COR-4510120.

Installation & Fabrication Notes

• No cutting or drilling required — bolt-in installation using OEM rear track bar bolts.
• Remove the factory rear track bar from both the frame mount and axle mount.
• Install this adjustable track bar in the factory rear track bar positions using the OEM bolts.
• Set the track bar length with the vehicle at ride height and the rear axle centered under the vehicle — adjust until the axle is centered laterally with equal clearance on both sides.
• Torque all hardware to specification at ride height.
• Verify rear axle centering and tire clearance after installation — re-check after the first 500 miles of use.
• The differential cover clearance bend is designed for the JK rear axle differential cover — verify clearance with aftermarket differential covers before installation.

Wheel & Tire Fitment

Compatible with standard JK wheel and tire combinations at 2–5" of lift. Rear track bar length affects rear axle centering and tire clearance — verify equal clearance on both sides after setting the track bar length.

Engineering Question: What is your current lift height on the JK? This track bar is designed for 2–5" of lift — if you're running less than 2" or more than 5", verify the adjustment range covers your specific lift height before ordering. Also confirm your vehicle is a 2007–2018 Jeep Wrangler JK — for the JL, order COR-4509110; for the JT, order COR-4510120.
