Clayton Off Road Adjustable Rear Track Bar | FK Heim Joint | Right-Hand Threaded Hex Body | 100% Bolt-On | 0"–4" Rear Lift | 2018–2026 Jeep Wrangler JL | SKU: COR-4509110

Verified Fitment

This rear track bar fits the 2018 through 2026 Jeep Wrangler JL — 2-Door and 4-Door Unlimited — in all trims. It is designed for JL builds with 0" to 4" of rear lift. This bar is not confirmed for the Gladiator JT — JL only..

What this corrects: When the rear of the JL is lifted, the rear axle shifts laterally off-center — the factory track bar holds the axle in a position calibrated for stock ride height. This adjustable rear track bar corrects axle centering by threading to the correct length for your rear lift height, re-centering the rear axle.

Installation Notes

Skill level: Intermediate. True bolt-on — no welding, drilling, or fabrication required. The critical pre-installation step is setting the correct bar length for your rear lift height before the bar is installed.

Step 1 — Set bar length:

1. Confirm your rear lift height.
2. Set the bar to the correct length for your rear lift height by rotating the hex body. Consult Clayton's length specification for your lift height or text (469) 407-7538 for the correct setting.

Step 2 — Installation:

1. Remove the factory rear track bar.
2. Install COR-4509110 in the factory rear track bar mounting positions — bolt-on, no modification required.
3. Torque all mounting hardware at ride height — not at full droop or compression.

Step 3 — Verification:

1. Verify rear axle is centered laterally — measure distance from axle tube to chassis reference points on both sides to confirm equal offset.
2. Schedule rear alignment check after installation.

Common Questions

Why does my lifted JL need an adjustable rear track bar?
The rear track bar holds the rear axle in its lateral position relative to the chassis. The factory rear track bar is a fixed length calibrated for stock ride height geometry. When the rear of the JL is lifted, the axle drops relative to the chassis and the factory bar pulls the axle off-center laterally. The result is a rear axle that sits to one side, which shows up as uneven tire clearance on each side and off-center steering if the front is not also off-center. An adjustable rear track bar corrects the rear axle lateral position for the new, lifted geometry.

What is the hex body design and why does it matter?
The bar body is machined as a right-hand threaded hex — a six-sided shape that a standard wrench can grip at any point along its length. This allows the bar length to be adjusted without removing the bar from the vehicle — loosen the jam hardware, apply a wrench to the hex body, rotate to the correct length, retighten. Most adjustable track bars require removal for adjustment because the bar body is round and cannot be gripped without special tools. The hex body eliminates that.

Does this fit the Gladiator JT?
The source documentation for COR-4509110 specifies the Jeep Wrangler JL — the Gladiator JT is not confirmed in available source data for this bar. Text (469) 407-7538 to confirm JT fitment before ordering.

How do I know what length to set the bar?
Length is specific to your rear lift height. Text (469) 407-7538 with your JL's rear lift height and OFAS will confirm the correct bar length setting before your order ships.

What is the difference between this and a front adjustable track bar?
Position and function. The front adjustable track bar (such as COR-5209011 or COR-5209010) corrects the front axle's lateral centering after front suspension lift — the front axle shifts when the front is lifted. This rear track bar corrects the rear axle's lateral centering after rear suspension lift — the rear axle shifts when the rear is lifted. They address the same type of geometry error at different ends of the vehicle.

What is the warranty?

The Obsidian Take

This bar is for the JL Wrangler owner who has lifted the rear of the truck and wants the rear axle centered correctly — not pulled to one side by the factory fixed-length track bar. The FK heim joint provides the angular articulation the lifted rear suspension geometry demands, and the right-hand threaded hex body makes length adjustment a wrench-on-the-vehicle operation rather than a remove-the-bar operation.

The 0"–4" rear lift range is the fitment gate. At 0" (stock height) the factory bar still functions, but the adjustable bar is a meaningful upgrade for any JL where the rear has been lifted within that range. Above 4" of rear lift, confirm adjustment range sufficiency with OFAS before ordering.

It is not confirmed for the Gladiator JT — JL only per source. It is not for the JK, TJ, or LJ. And it is not installed correctly without first setting the bar length for the specific rear lift height — the adjustment capability is the feature, and it requires one input from the builder before the bar goes on the truck.

Manufacturer Data Disclaimer

Product specifications and fitment data are sourced from Clayton Off Road product documentation and authorized product information. Actual product dimensions, adjustment range, and compatibility may vary by specific vehicle configuration, lift height, and manufacturer updates. Confirm length setting and fitment with Clayton or OFAS before installation.

Non-Returnable Notice

Suspension components are non-returnable once installed. Confirm fitment (2018–2026 Jeep Wrangler JL only — JT not confirmed), rear lift height (0"–4" confirmed adjustment range), and correct bar length setting before ordering. Text (469) 407-7538 with any fitment or configuration questions before your order is placed.
