Clayton Off Road 3-Link Upper Mount Bracket Kit for 1993-1998 Jeep Grand Cherokee ZJ

Is This for You?

• You're upgrading your ZJ Grand Cherokee's pocket-style crossmember to a 3-link rear suspension setup and need the upper control arm mount brackets — these two brackets weld directly to the top of the existing Clayton ZJ crossmember, converting it from a standard crossmember to a 3-link upper mount without replacing the entire crossmember.
• You want to add a triangulated upper control arm to your ZJ build without fabricating upper mounts from scratch — the angled back side and return on each bracket are pre-formed to align correctly with the upper 3-link crossmember mount position, eliminating the layout and fitment work of a raw bracket build.
• You're running or planning to run the optional Clayton ZJ axle truss (COR-1130101) and need the matching upper mount brackets — the opposite side of each bracket is designed to weld to the Clayton truss, creating a complete upper mount assembly when used together.

The Result

• Two pocket-style 3-link upper mount brackets — weld to the top of the Clayton ZJ crossmember to add a triangulated upper control arm mount without replacing the crossmember.
• Angled back side with return — pre-formed geometry aligns the bracket correctly to the upper 3-link crossmember mount position without additional layout or fitting.
• Compatible with optional Clayton ZJ axle truss (COR-1130101) — the truss-side face of each bracket is designed to weld directly to the truss for a complete upper mount assembly.

The COR-1130300 is a two-piece weld-on bracket kit that upgrades Clayton Off Road's pocket-style ZJ Grand Cherokee crossmember to a 3-link rear suspension configuration. The brackets weld to the top of the crossmember and provide the upper control arm mount point required for a triangulated 3-link setup. Each bracket features an angled back side with a return — a pre-formed geometry that aligns the bracket to the correct upper mount position relative to the crossmember without requiring the fabricator to lay out and fit a flat bracket from scratch. The opposite face of each bracket is designed to weld to the optional Clayton ZJ axle truss (COR-1130101), creating a complete upper mount assembly when the truss and brackets are used together. Critical installation note: the brackets must be welded to the top of the crossmember before the crossmember is installed in the vehicle — once the crossmember is in place, access to the upper mount weld area is restricted and a full-penetration weld cannot be completed. Sold as a set of 2 brackets. Made in the USA.

Audit Table

Verified Fitment (OFAS Standard)

✅ Fits 1993–1998 Jeep Grand Cherokee ZJ — 3-Link Upper Mount Bracket Kit for Clayton ZJ Crossmember
❌ Does NOT fit Jeep Cherokee XJ — different crossmember and rear suspension architecture
❌ Does NOT fit Jeep Grand Cherokee WJ (1999–2004) — different rear suspension design
❌ Does NOT fit non-Clayton crossmembers — bracket geometry is specific to Clayton's ZJ pocket-style crossmember
❌ Not a standalone upper mount — requires Clayton ZJ crossmember as the base structure

Installation & Fabrication Notes

• Critical sequence: weld brackets to the crossmember BEFORE installing the crossmember in the vehicle. Once the crossmember is installed, access to the upper mount weld area is blocked and a full-penetration weld cannot be completed.
• Clean the crossmember top surface to bare metal in the bracket contact zone before fitting — remove paint, primer, and mill scale for full-penetration welds.
• Dry-fit both brackets to the crossmember and verify alignment to the upper 3-link mount position before tacking — the angled back side and return must seat flush against the crossmember surface.
• Tack both brackets in position and verify symmetry and alignment before final welding.
• Full-penetration MIG or TIG welds on all bracket-to-crossmember contact surfaces — do not stitch weld only on load-bearing joints.
• If using the optional COR-1130101 truss, weld the truss-side face of each bracket to the truss before crossmember installation as well.
• After welding, coat all bare metal with weld-through primer and chassis paint to prevent corrosion at weld zones.

Wheel & Tire Fitment

Suspension bracket kit — no direct wheel or tire fitment restriction. Upper control arm geometry and tire clearance are determined by your 3-link arm length, lift height, and axle position, not by these brackets alone.

Engineering Question: Have you confirmed you are using the Clayton Off Road pocket-style ZJ crossmember as your base structure? These brackets are dimensioned for Clayton's specific crossmember geometry — they will not align correctly on a non-Clayton or aftermarket crossmember. Also confirm whether you are using the optional COR-1130101 truss, as the truss-side weld face on each bracket must be welded before crossmember installation.
