Fitment, Shipping & Product Support
Verified Fitment
This connecting rod is a hardware component, not a vehicle-specific part. Fitment is determined by thread specification and length requirement — not by year, make, or model.
This rod is compatible with:
| Application | Thread Required | Length Required | Notes |
|---|---|---|---|
| Clayton Off Road sway bar end link assemblies | 1/2"-20 fine thread | 13" overall | Direct replacement for COR-5109001 in Clayton kits |
| COR-5109110 (JK front/rear sway bar end links) | 1/2"-20 | 13" | Replacement connecting rod for one end link |
| COR-5109100 (JL/JT front sway bar end links) | 1/2"-20 | 13" | Replacement connecting rod for one end link |
| Custom sway bar end link fabrication | 1/2"-20 fine thread rod ends and jam nuts | Application-dependent | Verify end link geometry at your lift height before ordering |
Sold individually — one rod per order. Most sway bar end link applications require two rods, one per side. Order the correct quantity for your build before placing the order.

Does NOT Fit
| Exclusion | Reason |
|---|---|
| Sway bar kits using 9/16" thread connecting rods | Thread pitch does not match — 9/16" rod ends and jam nuts will not thread onto a 1/2"-20 stud |
| Sway bar kits using 5/8" thread connecting rods | Same — thread pitch mismatch |
| Metric thread sway bar kits | 1/2"-20 is SAE fine thread — metric rod ends will not engage correctly |
| Applications requiring longer or shorter connecting rods | This rod is 13" overall with 5.375" of thread each end. If your end link geometry requires a different length, this rod will not produce the correct sway bar angle at ride height. |
| Suspension pivot bolts or control arm applications | This is a sway bar end link connecting rod only — not rated for suspension pivot loads |
| Buyers who need a complete end link pair | This rod is sold individually. One rod is one side of one end link. Two rods are required for a complete pair covering one sway bar position. |

What Is and Is NOT Included
Included:
| Component |
|---|

Not Included:
| Item | Notes |
|---|---|
| Rod ends / tie rod ends | Sold separately — order 1/2"-20 rod ends compatible with your kit (AMP-TE-H502-12MM-W for Clayton applications) |
| Jam nuts | Sold separately — 1/2"-20 SAE J995 Grade 5 (FAS-36260 for Clayton applications) |
| Second rod for opposite side | This is a single rod. A complete sway bar end link pair requires 2 rods — order quantity 2 for both sides. |
| FK heim joints or aluminum spacers | Used in COR-5109100 (JL/JT front end links) at the passenger-side bracket — not included with this rod |
Critical Compatibility
| Condition | Interaction | Action Required |
|---|---|---|
| Thread direction — RH vs. LH | Adjustable sway bar end links use right-hand thread on one end and left-hand thread on the other to allow length adjustment by rotating the rod body. Confirm the thread direction on both ends of your existing rod before ordering a replacement — this rod is 1/2"-20 UNF, but confirm RH/LH configuration matches your kit. | Text (469) 407-7538 with your kit SKU to confirm correct thread direction configuration. |
| Thread engagement limit | The threaded section on each end is exactly 5.375". Do not thread a rod end or jam nut beyond the threaded section into the rod body — this will damage the stud body and compromise thread engagement. | Count thread engagement and stop before reaching the unthreaded center section. |
| Rod end thread compatibility | This stud accepts standard 1/2"-20 UNF rod ends, tie rod ends, and jam nuts. FK heim joints with 1/2"-20 threads are also compatible. Confirm your rod end thread bore is 1/2"-20 fine thread before ordering. | Verify rod end internal thread spec before ordering. |
| Anti-seize in high-corrosion environments | Yellow zinc chromate finish provides enhanced corrosion resistance, but in salt, mud, or frequent submersion conditions, applying anti-seize compound to the threads before assembly further prevents thread galling and seizure. | Apply anti-seize to both threaded ends before assembly in aggressive environments. |
| Bending deformation inspection | A bent connecting rod is a sign that the end link geometry is incorrect for the lift height or that the rod is undersized for the application load. A bent rod must be replaced — do not attempt to straighten and reinstall. | Inspect connecting rod for straightness after any hard trail use or end link contact event. Replace if bent. |
Installation Notes
Skill level: Beginner. Hardware component — no special tools required beyond a wrench and torque wrench.
Installation summary:
- If replacing a damaged rod, remove the old rod from the end link assembly — thread jam nuts and rod ends off both ends.
- Thread new jam nuts onto both ends of the COR-5109001 connecting rod before threading on rod ends — jam nuts must go on first.
- Thread rod ends onto each end of the stud to the correct engagement depth for your lift height. Verify the same depth on both ends.
- Torque jam nuts against the rod end body to lock length — per your sway bar kit's torque specification (or SAE standard for 1/2"-20 Grade 5 hardware if no kit spec is available).
- Install the assembled end link in the sway bar mount positions.
- Torque all mounting hardware at ride height.
- Verify minimum thread engagement (≥3 full threads at the maximum length setting used) on both ends.
Required tools:
| Tool | Required |

| Wrench or socket set | Yes |

Common Questions
Why is this rod 1541 steel instead of standard mild steel?
1541 steel is a resulfurized and rephosphorized carbon steel with higher tensile and yield strength than standard 1018 or 1020 mild steel. For a sway bar end link connecting rod that sees bending and tension loads through the full suspension articulation range, the higher strength spec reduces the risk of deformation under sustained lateral load. Clayton uses it in their production sway bar kits for this reason — this replacement rod matches the original material spec.
What is yellow zinc and why is it better than clear zinc?
Yellow zinc (also called gold zinc or yellow chromate) is a zinc plate with a chromate conversion coating that adds a second layer of corrosion protection over the zinc. Clear zinc has only the zinc plate layer. In trail use — mud, water, salt — the chromate layer meaningfully extends the corrosion resistance compared to clear zinc hardware. The yellow color is a visual indicator that the chromate conversion is present.
I need one rod for each side — do I order quantity 2?
Yes — this rod is sold individually. One rod covers one side of one sway bar position. A complete sway bar end link set covering one position (both sides) requires 2 rods. Order quantity 2 for a complete pair.
Can I use this rod in a custom end link setup?
Yes — provided your rod ends and jam nuts are 1/2"-20 fine thread (UNF) and 13" overall length is correct for your end link geometry at your lift height. Confirm your sway bar mount geometry and required end link length before ordering for a custom application. Text (469) 407-7538 if you need help confirming the correct length for your specific lift height.
The Obsidian Take
This rod is for two buyers: the Clayton kit owner who bent or stripped a connecting rod and needs an exact replacement, and the fabricator building a custom sway bar end link system around 1/2"-20 hardware. Both buyers need the same thing — correct thread pitch, correct length, correct material, correct finish. COR-5109001 is what Clayton uses in their production kits (COR-5109100 and COR-5109110) because the spec is correct for the application. A replacement from a hardware bin in a different steel grade and a clear zinc finish is not the same part.
The single-unit sale is the detail that catches buyers off-guard. One rod is one side. Two rods are a pair. The order quantity needs to match the application before checkout.
It is not a complete end link kit — rod ends, jam nuts, and FK heim joints are separate components. It is not a suspension pivot bolt — the application is sway bar end links only. And it is not the correct rod if your kit uses a 9/16" or 5/8" thread stud — thread pitch is the only fitment gate, and it needs to be confirmed before ordering.
Manufacturer Data Disclaimer
Product specifications are sourced from Clayton Off Road product documentation. Actual product dimensions, material grade, and thread specifications may vary by manufacturer updates. Confirm thread pitch and length requirements against your specific sway bar kit before ordering.
Non-Returnable Notice
Hardware components are non-returnable once installed. Confirm thread specification (1/2"-20 fine thread), overall length (13"), and required quantity (2 per complete sway bar position) before ordering. Text (469) 407-7538 with any application questions before your order is placed.
