Clayton Off Road Upper Control Arm GIIRO Bushing Housing for 1997-2006 Jeep Wrangler TJ/LJ and 1993-1998 Grand Cherokee ZJ

Is This for You?

• You're rebuilding a Clayton upper control arm on your TJ, LJ, or ZJ and the axle-side housing is worn, cracked, or out of spec — this is the correct OEM-replacement steel housing for the front upper control arm axle-side mount.
• You're upgrading from a rubber bushing to a Clayton GIIRO dual-durometer bushing — this 2.25" OD housing is machined to accept both GIIRO and standard Clevite-style rubber bushings without modification.
• You're building a custom upper control arm and need a correctly dimensioned housing — 2.250" OD / 1.875" ID / 1.500" width gives you the exact bore and shoulder spec for a press-fit bushing installation.

The Result

• Steel construction at 2.250" OD / 1.875" ID / 1.500" width — precise dimensions for axle-side front upper control arm mount on TJ, LJ, and ZJ platforms.
• Accepts Clayton GIIRO dual-durometer bushing or standard Clevite-style rubber bushing — no housing modification required for either application.
• Direct replacement for worn or damaged OEM-spec housings — restores correct bushing bore geometry and eliminates slop at the axle mount.

The COR-2300109 is a steel upper control arm bushing housing machined to the front axle-side specification for Jeep Wrangler TJ/LJ (1997–2006) and Grand Cherokee ZJ (1993–1998) upper control arm applications. The 2.250" outer diameter and 1.875" inner diameter provide the correct press-fit bore for Clayton's GIIRO dual-durometer bushing — a maintenance-free, self-centering design that allows up to 30° of misalignment without binding. The 1.500" width matches the OEM axle bracket ear spacing on these platforms, ensuring proper shoulder contact and eliminating lateral float under load. The housing is also dimensionally compatible with standard Clevite-style rubber bushings for applications where NVH isolation is prioritized over articulation. Steel construction resists deformation under the clamp loads typical of lifted TJ/LJ/ZJ builds running 3"–5" of lift. Sold as a single housing.

❌ Does NOT fit rear control arm positions — axle-side front upper mount only

Installation & Fabrication Notes

• Housing requires press-fit bushing installation — do not hammer bushing in without a proper bushing press or C-clamp press tool.
• Verify axle bracket ear width matches 1.500" housing width before installation — shimming may be required on modified axle housings.
• When installing a GIIRO bushing: ensure the dual-durometer outer layer seats fully flush with the housing shoulder on both faces.
• When installing a Clevite-style rubber bushing: apply rubber lubricant (not petroleum-based) during press-in to prevent tearing.
• Torque axle-side UCA bolt to your specific Clayton arm specification — verify with Clayton's torque spec sheet for your kit.
• Inspect housing bore for ovality or scoring before pressing in a new bushing — a worn bore will not retain the bushing under load.

Wheel & Tire Fitment

Bushing housing component — no direct wheel or tire fitment restriction. Compatible with standard TJ/LJ/ZJ wheel and tire combinations up to 35" tires on 3"–5" lift. Larger tire fitment may require additional suspension geometry correction.

Engineering Question: Are you replacing a housing on an existing Clayton upper control arm, or building a new arm? Confirm your axle bracket ear spacing is 1.500" and your bushing OD is 1.875" before pressing. Using an incorrect bushing OD in this housing will result in improper retention and potential joint separation under load.
