Verified Fitment
This bushing fits the 2007 through 2018 Jeep Wrangler JK — 2-Door and 4-Door Unlimited — in all trims. It is the passenger side upper knuckle interface component for Clayton's JK drag link flip system. The JL, JT, and TJ/LJ are not compatible due to different front knuckle geometry.
| Year Range | Make | Model | Configuration | Application |
|---|---|---|---|---|
| 2007–2018 | Jeep | Wrangler JK | 2-Door | Drag link flip — passenger side upper knuckle |
| 2007–2018 | Jeep | Wrangler JK Unlimited | 4-Door | Drag link flip — passenger side upper knuckle |
This bushing does not complete the drag link flip on its own. The complete Clayton JK drag link flip system requires all three components: this bushing (COR-5208210), the Clayton RHD drag link, and the COR-5208110 track bar bracket. Do not order this bushing unless you are also ordering or already have the companion parts.

Does NOT Fit
| Exclusion | Reason |
|---|---|
| Jeep Wrangler JL (2018–2026) | Different front knuckle geometry — this bushing is dimensioned for the JK passenger side upper knuckle specifically |
| Jeep Gladiator JT (2020–2026) | Different front knuckle geometry |
| Jeep Wrangler TJ / LJ (1997–2006) | Different front knuckle architecture |
| Jeep Wrangler YJ / CJ | Not applicable |
| Knuckles drilled to any size other than exactly 7/8" | Undersized bore: bushing will not seat. Oversized bore: bushing will be loose and move under steering load — permanently compromising the knuckle. The bore must be drilled to exactly 7/8" on-axis. |
| Buyers who do not have or are not ordering the Clayton RHD drag link and COR-5208110 | Installing this bushing without the companion parts results in a drilled, unfinished knuckle with no functional benefit. All three components are required for the drag link flip to function correctly. |
| Buyers without access to a drill press or equivalent bore-guiding equipment | An angled or off-axis bore will misalign the drag link end and cause binding through the steering sweep. Freehand drilling is not acceptable for this application. |

Not Included:
| Item | Notes |
|---|---|
| Clayton RHD drag link | Required to complete the drag link flip. Mounts into this bushing at the passenger side upper knuckle. Must be ordered separately if not already in hand. |
| COR-5208110 track bar bracket | Required to correct track bar geometry at the same time as the drag link flip. Installing the drag link flip without the track bar correction will not fully resolve steering geometry issues at lift. Must be ordered separately if not already in hand. |
| 7/8" drill bit and drill press | Required for knuckle bore preparation. Tools not included — a drill press or bore-guiding equivalent is required for an on-axis bore. |
| Bushing press or installation driver | Required to seat the bushing without distortion. Hammering the bushing in without a driver risks deforming the bore. |
| Professional installation labor | Not included. |
No required companion hardware confirmed beyond the Clayton RHD drag link and COR-5208110 for standard JK drag link flip applications.
Critical Compatibility
| Condition | Interaction | Action Required |
|---|---|---|
| Exact 7/8" bore required — permanent modification | Drilling the passenger side upper knuckle to 7/8" is an irreversible chassis modification. An undersized bore prevents the bushing from seating. An oversized bore creates a loose fit — the bushing will move under steering load, creating slop and accelerated wear. There is no remediation for an oversized bore short of knuckle replacement. | Use a drill press or bore guide for an on-axis, precision 7/8" bore. Do not freehand drill. Confirm bit size is exactly 7/8" before drilling. |
| On-axis bore requirement | The bushing must be installed on-axis (perpendicular to the knuckle surface) for the drag link end to sweep correctly through the full steering arc. An angled bore misaligns the drag link end and causes binding at the extremes of steering travel. | Drill press only — no exceptions for a component driving steering geometry. |
| Bushing installation — press fit | The bushing is dimensioned for a press fit. Uneven driving force (hammering without a driver) distorts the bushing bore, changing the internal geometry that accepts the drag link end. A distorted bore creates binding or slop at the drag link connection. | Use a proper press or a parallel-faced driver for even seating force. |
| System completeness — all three parts required | This bushing seated in the knuckle provides the mount point. The Clayton RHD drag link provides the geometry correction. COR-5208110 corrects track bar geometry simultaneously. Any one of the three missing from the build leaves the system non-functional or incompletely corrected. | Confirm all three components are in hand or on order before drilling the knuckle. |
| Post-installation alignment | A drag link flip changes front steering geometry — caster, toe, and Ackermann angle are all affected. A full front alignment (caster, toe) is mandatory after complete installation. | Schedule alignment after all three components are installed and torqued. |
Skill level: Advanced. Drilling a steering knuckle bore is a precision fabrication step — not a general mechanic task. A drill press or equivalent bore-guiding equipment is required. This is a permanent modification; errors are not recoverable without knuckle replacement.
Pre-installation checklist — confirm before drilling:
- All three system components are in hand: COR-5208210 (this bushing), Clayton RHD drag link, COR-5208110 track bar bracket
- 7/8" drill bit is confirmed at correct size
- Drill press or bore guide is available and set up
- Knuckle is removed from the vehicle or secured for drilling
Step-by-step installation summary:
- Remove the passenger side upper knuckle or secure the vehicle for in-place drilling — the bore must be drilled on-axis.
- Drill the passenger side upper knuckle bore to exactly 7/8" using a drill press or bore guide. A straight, on-axis bore is required. Clean the bore after drilling.
- Press the bushing into the drilled bore using a press or parallel-faced driver — do not hammer in without a driver. Press until fully seated and flush with the knuckle surface.
- Verify the bushing is fully seated with no movement before proceeding.
- Install the Clayton RHD drag link end into the seated bushing — torque to Clayton's specification.
- Install COR-5208110 track bar bracket concurrently — do not complete the drag link flip without the track bar correction.
- Complete full front alignment (caster, toe) after all components are installed and torqued.

Common Questions
What is a drag link flip and why does my JK need it?
The factory JK uses a left-hand drive drag link configuration — the drag link runs from the driver side of the pitman arm to the driver side of the steering knuckle. On a lifted JK, this geometry creates Ackermann errors and binding through the steering arc because the drag link and tie rod no longer operate at the same angle. A drag link flip moves the drag link mount to the passenger side upper knuckle, converting the system to a right-hand drive configuration that corrects the geometry at lift. The factory passenger side upper knuckle has no mount point for the drag link — this bushing creates it.
Can I install this bushing without the Clayton RHD drag link and COR-5208110?
Mechanically, the bushing can be pressed in. Functionally, installing this bushing without the companion parts results in a drilled knuckle that does nothing — you have modified a steering component permanently and gained no benefit. Do not drill the knuckle until all three system components are in hand.
What happens if I drill the bore slightly too big?
The bushing will be loose — it will not be a press fit and will move under steering load. A loose bushing in a steering knuckle creates slop in the drag link connection, which translates directly into steering wander and accelerated wear. The bore cannot be undersized again once drilled. Knuckle replacement is the only remediation for an oversized bore.
Can I drill the knuckle freehand with a hand drill?
No. The bore must be on-axis — perpendicular to the knuckle surface — for the drag link end to sweep correctly through the full steering arc without binding. Freehand drilling does not provide the accuracy required. A drill press or bore guide is necessary.
Does this require a front alignment after installation?
Yes — a full front alignment (caster and toe at minimum) is mandatory after completing the drag link flip. The geometry change affects tire wear and steering feel; driving at highway speed without a post-install alignment accelerates tire wear and produces vague or pulling steering.
The Obsidian Take
This bushing is for the JK owner who is building the complete Clayton drag link flip system and needs the knuckle interface component. It is a precision-machined press-fit part for a permanent knuckle modification — not an accessory, not a bolt-on upgrade. The drag link flip is a geometry correction for lifted JKs that experience steering binding, Ackermann error, or bump steer caused by the factory LHD drag link configuration. This bushing is the starting point of that correction, but it is only the starting point.
It is not for any buyer who does not also have the Clayton RHD drag link and COR-5208110 track bar bracket in hand or on order — drilling the knuckle without a complete system plan is an irreversible mistake. It is not for any buyer without access to a drill press or equivalent boring equipment — freehand drilling at this precision level is not an option in steering geometry work. And it is not for the JL, JT, or TJ/LJ owner — the front knuckle geometry on those platforms is different.
Order this bushing as part of the complete system build, not ahead of it.
