Fitment, Shipping & Product Support
Verified Fitment
This rear track bar fits the 2007 through 2018 Jeep Wrangler JK — 2-Door and 4-Door Unlimited — in all trims. It is designed for JK builds with 0" to 6" of rear lift. No welding required. This is the adjustable bar replacement option — for the weld-on relocation bracket that works with the factory JK rear track bar, see COR-4508200.
| Year Range | Make | Model | Configuration | Rear Lift Range | Installation |
|---|---|---|---|---|---|
| 2007–2018 | Jeep | Wrangler JK | 2-Door | 0"–6" rear lift | 100% bolt-on |
| 2007–2018 | Jeep | Wrangler JK Unlimited | 4-Door | 0"–6" rear lift | 100% bolt-on |
What this corrects: When the rear of the JK is lifted, the rear axle shifts laterally off-center — the factory track bar is a fixed length calibrated for stock ride height. This adjustable rear track bar replaces the factory bar and is set to the correct length for the lifted geometry, re-centering the rear axle.

Critical Compatibility
| Condition | Interaction | Action Required |
|---|---|---|
| Bar length must match rear lift height | The bar must be adjusted to the correct length for your specific rear lift height before installation. Installing at the wrong length leaves the rear axle off-center. | Confirm rear lift height and set bar to correct length before installation. Text (469) 407-7538 to confirm the correct setting. |
| 6" maximum confirmed range | Adjustment range is confirmed for 0"–6". Rear lifts above 6" may exceed the bar's usable adjustment range. | Confirm rear lift height is 6" or less before ordering. |
| Heim joint inspection | The heim joint at the track bar end allows angular articulation through the full rear suspension travel arc. Inspect periodically for wear or looseness. Heim joints must be set to the correct length precisely — they do not self-center under compression the way rubber bushings do. | Inspect heim joint on regular service schedule. Set bar length accurately before installation. |
| Hex body — in-vehicle adjustment | Wrench access at any flat of the hex body allows length adjustment without removing the bar. | Apply wrench to hex flat, rotate to correct length, torque mounting hardware. |
| COR-4508200 vs. COR-4508110 — JK buyer decision | COR-4508200 is the weld-on relocation bracket — it moves the factory bar's frame mount and allows factory bar reuse; designed for 2.5"–4.5" lift only. COR-4508110 (this bar) replaces the factory bar entirely; works from 0"–6" of rear lift; bolt-on. If the factory bar is worn and needs replacement anyway, COR-4508110 is the correct purchase. If the factory bar is serviceable and welding capability is available, COR-4508200 may be more cost-effective. | Evaluate factory bar condition and lift height range to determine the correct JK rear track bar solution. Text (469) 407-7538 to confirm. |
| Rear alignment after installation | Replacing and adjusting the rear track bar changes the rear axle's lateral position. A rear alignment check is recommended after installation. | Schedule rear alignment after installation. |
Installation Notes
Skill level: Intermediate. True bolt-on — no welding, drilling, or fabrication required. Set bar length before installation.
Step 1 — Set bar length:
- Confirm rear lift height.
- Set bar to the correct length for your rear lift height by rotating the hex body. Text (469) 407-7538 with your rear lift height for the correct length setting.
Step 2 — Installation:
- Remove the factory JK rear track bar.
- Install COR-4508110 in the factory rear track bar mounting positions — bolt-on, no modification required.
- Torque all mounting hardware at ride height — not at full droop or compression.
Step 3 — Verification:
- Verify rear axle is centered laterally.
- Schedule rear alignment check.
Required tools:
| Tool | Required |
|---|---|
| Standard socket and wrench set | Yes |
| Torque wrench | Yes |
| Measuring tape (for axle centering verification) | Recommended |
Common Questions
What is the difference between this and COR-4508200 (weld-on relocation bracket)?
Solution approach and lift range. COR-4508200 is the weld-on relocation bracket — it moves the factory JK rear track bar's frame-side mount point and allows the factory bar to be reused. It is designed specifically for 2.5"–4.5" of rear lift and requires permanent welding. COR-4508110 (this bar) replaces the factory bar entirely with an adjustable bolt-on bar that covers 0"–6" of rear lift without welding. If your factory bar is worn and needs replacement, this bar is the correct purchase. If your factory bar is serviceable and you have welding capability, COR-4508200 may be the more cost-effective option at 2.5"–4.5" of lift. Text (469) 407-7538 if unsure which solution fits your build.
Why does my lifted JK need a rear track bar correction?
The factory JK rear track bar is fixed-length and calibrated for stock ride height. After a rear lift, the axle drops relative to the frame and the factory bar holds the rear axle off-center laterally. An off-center rear axle shows up as uneven tire clearance left-to-right and rear end instability. This adjustable bar replaces the factory bar and is set to the correct length for the lifted geometry, re-centering the rear axle.
Does this fit the JL Wrangler?
No — the JL uses a different rear track bar geometry. The JL adjustable rear track bar is COR-4509110.
How do I set the correct bar length for my lift height?
Rotate the hex body with a wrench until the bar reaches the correct length for your rear lift height. Text (469) 407-7538 with your JK's rear lift height and OFAS will confirm the correct setting before your order ships.

The Obsidian Take
This bar is for the JK owner who has lifted the rear of the truck and wants the rear axle centered correctly with a bolt-on replacement for the factory track bar. The adjustable hex body and heim joint provide correct geometry correction from stock height through 6" of rear lift — the widest confirmed rear lift range of any track bar product in the JK lineup covered in this session.
The buyer decision between this bar and COR-4508200 (weld-on relocation bracket) comes down to three factors: factory bar condition, available lift range, and welding capability. If the factory bar is worn — replace it with this bar. If the factory bar is serviceable, lift height is 2.5"–4.5", and welding is available — COR-4508200 may be the more cost-effective path. If lift height is outside that 2.5"–4.5" window or welding is not available — this bar is the correct choice.
It is not for the JL — that is COR-4509110. It is not for the TJ, LJ, or any Grand Cherokee or Cherokee platform. And it is not installed correctly without first setting the bar length for the specific rear lift height.

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 (2007–2018 Jeep Wrangler JK — not JL, JT, or TJ), rear lift height (0"–6" confirmed range), and correct bar length setting before ordering. Text (469) 407-7538 with any fitment or configuration questions before your order is placed.
