Fitment, Shipping & Product Support
The Clayton Off Road 4 Link Axle Truss Builder Series (SKU COR-1200020) is the tab-less version of Clayton's rear axle truss for fabricators building custom triangulated 4-link or upper control arm systems. Pre-welded truss body, CNC laser-cut from a combination of 1/4" and 3/16" high-strength steel — heavier gauge at primary load-bearing sections of the housing bridge, lighter gauge at secondary sections to manage weight without compromising axle wrap and lateral load distribution. Four equal-length tabs are included loose, allowing the fabricator to trim each tab to the exact angle required for their control arm geometry before welding. Designed for the rear axle housing on 1997–2006 Jeep Wrangler TJ and LJ. Made in the USA. Lifetime limited warranty.
This is a weld-on fabrication component — professional welding and fabrication experience required. Confirm your specific axle (Dana 44 or Dana 35) and compatibility directly with Clayton Off Road before ordering.

What Is and Is NOT Included
| Item | Included |
|---|---|
| Pre-welded truss body | ✓ |
| 4 equal-length tabs (loose, untrimmed) | ✓ |
| Welding, cutting, or fabrication labor | ✗ NOT included — customer/installer fabrication required |
| Control arms or 4-link hardware | ✗ NOT included — this is the axle-side mounting structure only |
| Paint or powder coating | ✗ NOT included — bare metal weld zones require coating after installation |
Builder Series vs. Standard Tabbed Truss
| Version | Tab Configuration | Best For |
|---|---|---|
| Builder Series (this listing) | Tabs included loose — trim and weld at custom angle | Custom triangulated 4-link, non-standard lift heights, builder-specific pivot locations |
| Standard tabbed truss | Tabs pre-welded at fixed angle | Standard control arm geometry, faster install, no custom angle needed |
Verified Fitment
| Vehicle | Years | Axle | Status |
|---|---|---|---|
| Jeep Wrangler TJ | 1997–2006 | Dana 44 rear | ✓ |
| Jeep Wrangler LJ Unlimited | 2004–2006 | Dana 44 rear | ✓ |
| Jeep Wrangler TJ/LJ | 1997–2006 | Dana 35 rear | ⚠️ Conflicting information — confirm directly with Clayton Off Road before ordering |
| Jeep Wrangler JK | 2007–2018 | Any | ✗ Different rear axle housing geometry — Clayton makes a separate JK-specific truss (3/8" thick) |
| Jeep Grand Cherokee ZJ/WJ | Any | Any | ✗ Different axle housing profile |
| Jeep Cherokee XJ | Any | Any | ✗ Different rear axle housing |
| Ford 8.8 swap | Any | Any | ✗ Different housing profile — significant modification required |
Critical Compatibility
| Configuration | Notes |
|---|---|
| Dana 44 vs. Dana 35 | Verify your TJ/LJ's actual rear axle before ordering — non-Rubicon TJ/LJ models came standard with Dana 35. Check your axle tag or differential cover bolt pattern to confirm. |
| Jeep Wrangler JK | Does not fit — Clayton's JK truss is a separate, thicker (3/8") product for different housing geometry |
| Ford 8.8 rear axle swap | Not compatible without significant modification |
| Welding skill | This is a weld-on fabrication component, not a bolt-on kit — requires fabrication experience, proper welding equipment, and control arm geometry knowledge |
Common Questions
Does this fit a Dana 35 rear axle?
Conflicting information exists across Clayton's product line. A related Clayton truss description states compatibility with both Dana 35 and Dana 44 using the same material specification, but other sourcing for this exact SKU references Dana 44 specifically. Confirm directly with Clayton Off Road or text us your axle tag information before ordering.
Why are the tabs not pre-welded?
The Builder Series is designed for fabricators who need non-standard control arm angles — custom lift heights, triangulated geometry, or builder-specific pivot points that a fixed-angle tab can't accommodate. You trim and position each tab to your exact required angle before welding.
Do I need to paint or coat anything after welding?
Yes. Coat all bare metal at weld zones with weld-through primer or chassis paint after welding to prevent corrosion.
How do I know if my TJ/LJ has a Dana 44 or Dana 35?
Check your axle tag or count the differential cover bolts — this is the standard method, though always confirm against your specific VIN and axle tag rather than relying solely on bolt count, since variations exist.
Can this be used without building a full 4-link?
The truss itself strengthens the axle housing regardless of control arm configuration. The included tabs are specifically for triangulated upper control arm mounting — if you don't need that, a simpler non-tabbed truss may suit your needs better.
The Obsidian Take
The COR-1200020 is for the fabricator building a custom triangulated 4-link or upper control arm system on a TJ/LJ who needs Clayton's CNC-cut truss geometry without being locked into fixed tab positions. Pre-welded truss body, four loose tabs, full angle freedom for non-standard lift heights and builder-specific geometry.
This is not a bolt-on product — it demands real welding and fabrication skill, proper equipment, and control arm geometry knowledge. Confirm your rear axle (Dana 44 vs. Dana 35) before ordering, and if you're unsure, check your differential tag or text us your VIN and axle details before committing to this part.
