Fitment, Shipping & Product Support
Verified Fitment
This front 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 front lift. No welding required.
| Year Range | Make | Model | Configuration | Front Lift Range | Installation |
|---|---|---|---|---|---|
| 2007–2018 | Jeep | Wrangler JK | 2-Door | 0"–6" front lift | 100% bolt-on |
| 2007–2018 | Jeep | Wrangler JK Unlimited | 4-Door | 0"–6" front lift | 100% bolt-on |
What this corrects: When the front of the JK is lifted, the front axle shifts laterally off-center — the factory track bar is a fixed length calibrated for stock ride height. This adjustable front track bar replaces the factory bar and is set to the correct length for the lifted geometry, re-centering the front axle and restoring correct steering geometry.
If both front and rear of the JK are lifted: This bar corrects the front axle only. The rear axle requires COR-4508110 (JK adjustable rear track bar) or COR-4508200 (JK rear relocation bracket) for rear axle centering correction.

What Is and Is NOT Included
Included:
| Component |
|---|
| COR-4508100 adjustable front track bar with heim joint |
| Right-hand threaded hex body |
| Hardware per Clayton specification |
Not Included:
| Item | Notes |
|---|---|
| Rear axle track bar correction | This bar corrects the front axle only. If both front and rear are lifted, also order COR-4508110 (JK rear adjustable track bar) or COR-4508200 (JK rear relocation bracket). |
| Professional installation labor | Not included — bolt-on installation is intermediate level |
| Front alignment service | Full front alignment is recommended after installation — not included |
Critical Compatibility
| Condition | Interaction | Action Required |
|---|---|---|
| Bar length must match front lift height | The bar must be set to the correct length for your front lift height before installation. Installing at the wrong length leaves the front axle off-center — which shows up as uneven tire clearance, off-center steering, and handling that pulls to one side. | Confirm front lift height and set bar to correct length before installation. Text (469) 407-7538. |
| 6" maximum confirmed range | Above 6" of front lift, confirm the bar's adjustment range is sufficient before ordering. | Text (469) 407-7538 for lifts above 6". |
| Front and rear lift — both axles need correction | If both the front and rear of the JK have been lifted, both the front axle (this bar) and the rear axle (COR-4508110 or COR-4508200) need track bar correction. Installing this bar only while leaving the rear axle factory track bar in place centers the front but leaves the rear off-center. | Order COR-4508110 or COR-4508200 simultaneously if rear is also lifted. |
| Hex body in-vehicle adjustment | Apply a wrench to any flat on the hex body to rotate and adjust bar length without removing the bar. | Loosen mounting hardware, apply wrench to hex body, rotate to correct length, retorque. |
| Front alignment after installation | Replacing and adjusting the front track bar changes the front axle's lateral position. A full front alignment is required after installation. | Schedule front alignment immediately after installation — do not drive at highway speed before alignment is confirmed. |
| Heim joint inspection | The heim joint articulates through the full front suspension travel arc. Inspect periodically for wear or looseness. Set bar length precisely — heim joints do not self-center under compression. | Inspect on regular service schedule. |
Installation Notes
Skill level: Intermediate. True bolt-on — no welding, drilling, or fabrication required.
Step 1 — Set bar length:
- Confirm front lift height.
- Set bar to the correct length for your front lift height by rotating the hex body. Text (469) 407-7538 with your front lift height for the correct length setting.
Step 2 — Installation:
- Remove the factory JK front track bar.
- Install COR-4508100 in the factory front 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 front axle is centered laterally.
- Schedule front alignment immediately after installation.
Required tools:
| Tool | Required |
|---|---|
| Standard socket and wrench set | Yes |
| Torque wrench | Yes |
| Measuring tape (for axle centering verification) | Recommended |
Common Questions
Why does my lifted JK need an adjustable front track bar?
The factory JK front track bar holds the front axle in its lateral position relative to the chassis. The factory bar is a fixed length calibrated for stock ride height. After a front lift, the axle drops relative to the frame and the factory bar pulls the front axle laterally off-center. The result is uneven tire clearance left-to-right, a steering wheel that sits off-center at straight ahead, and handling that pulls slightly to one side. This adjustable bar replaces the factory bar and is set to the correct length for the lifted geometry, re-centering the front axle.
If I lift both the front and rear of my JK, do I need both track bars?
Yes — the front track bar corrects the front axle centering, and the rear track bar corrects the rear axle centering. These are two separate bars addressing two separate axles. If only the front is lifted, this bar alone is sufficient. If both front and rear are lifted, order COR-4508110 (JK rear adjustable track bar) or COR-4508200 (JK rear weld-on relocation bracket) alongside this bar.
What is the difference between this and the JL/JT front track bar (COR-4509100)?
Platform only — the JK and JL/JT front track bars address the same problem (front axle lateral centering after front lift) using the same hex body design. COR-4509100 specifies dual FK heim joints at both ends. This JK bar's heim joint brand is not confirmed in available source data. Both are bolt-on with the same 0"–6" lift range. Do not use a JL/JT bar on a JK, or vice versa — different mounting hardware and geometry.
How do I set the correct bar length?
Rotate the hex body until the bar reaches the correct length for your front lift height. Text (469) 407-7538 with your JK's front lift height and OFAS will confirm the correct setting before your order ships.
What is the warranty?

The Obsidian Take
This bar is for the JK owner who has lifted the front of the truck and wants the front axle centered correctly with a bolt-on replacement for the factory track bar. The adjustable hex body and heim joint provide geometry correction from stock height through 6" of front lift — the same lift range as the JK rear adjustable bar (COR-4508110) and the JL/JT front bar (COR-4509100).
The front and rear are separate problems requiring separate solutions. This bar handles the front axle. COR-4508110 or COR-4508200 handles the rear. A lifted JK with both axles off-center needs both solutions. A JK where only the front has been lifted needs only this bar.
It is not for the JL or JT — those platforms use COR-4509100. 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 front lift height — the hex body adjustment is the step that makes this bar work.
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 (2007–2018 Jeep Wrangler JK — not JL, JT, or TJ), front 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.
