Fitment, Shipping & Product Support
The Clayton Off Road Adjustable Rear Track Bar (COR-4510120) is the rear track bar for the 2020–2026 Jeep Gladiator JT, designed for 0" to 6" of lift. When a JT is lifted, the factory fixed-length rear track bar pulls the rear axle laterally off-center toward the driver side, causing uneven tire clearance and handling imbalance. This adjustable bar corrects that offset by allowing precise length adjustment to re-center the rear axle at ride height. Built from 1-3/8" x 5/16" DOM tubing with a clearance bend specifically engineered to clear a full-size 37" spare tire mounted on the rear carrier — a common interference point on lifted JT builds. Forged GIIRO dual-durometer bushing adjuster — maintenance-free, NVH-isolating, self-centering, full articulation. Bolt-in installation reuses OEM bolts — no cutting or drilling required. Approximately 1-hour install. Lifetime, no-questions-asked warranty against bending or breaking. Made in the USA. Also included standard in Clayton's complete JT suspension systems, or available separately as shown here.

Critical Compatibility
| Configuration | Notes |
|---|---|
| Lift above 6" | Not recommended — confirm your specific lift height falls within the 0–6" adjustment range |
| Spare tire larger than 37" | The clearance bend is engineered for 37" — larger spares (e.g., 38") may clear but could require additional steps like heat shield removal and reduced tire pressure; verify with your specific tire and carrier setup |
| Aftermarket swing-out rear carrier | Verify clearance with your specific carrier — the bend is designed around the factory rear carrier |
| 2.5" lift with existing relocation bracket | No relocation bracket is needed when using this adjustable track bar — remove if previously installed |
Common Questions
Does this track bar clear a 37" spare without removing the heat shield?
Yes, per verified installer feedback — no heat shield removal or other modification is needed for a 37" spare with this track bar.
Can I run a spare larger than 37"?
Possibly, but it's beyond this bar's designed spec. One verified buyer successfully ran a 38" spare but had to remove the heat shield and reduce tire pressure to clear the frame rails. Confirm clearance with your specific setup before assuming fitment.
Do I need a track bar relocation bracket with this?
No, not at moderate lift heights — confirmed for 2.5" lift specifically. If you have a previously installed relocation bracket, it can be removed once this adjustable track bar is installed.
How long does installation take?
Approximately 1 hour. No cutting or drilling required — this bolts in using the factory OEM bolts.
Does this fit a Wrangler JL?
No. The JL uses different rear track bar geometry and requires a separate Clayton SKU.
The Obsidian Take
The COR-4510120 is for the lifted JT owner who needs the rear axle re-centered and wants to run a full-size 37" spare without interference — a genuinely dual-purpose part that solves both problems in one bolt-in component. Forged GIIRO adjuster, DOM tubing, no drilling, about an hour to install, lifetime warranty against bending or breaking.
Confirm two things before ordering: your lift height falls within the 0–6" range, and if you're running anything larger than a 37" spare, verify clearance with your specific tire and carrier setup rather than assuming the same fit.
Non-Returnable Notice: Once installed, this product is non-returnable. Confirm lift height range and spare tire size before ordering.
