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.\u003c\/p\u003e\u003ch3\u003eAudit Table\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eCOR-2300109\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003eFront Upper Control Arm, Axle Side\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Diameter (OD)\u003c\/td\u003e\n\u003ctd\u003e2.250\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInner Diameter (ID)\u003c\/td\u003e\n\u003ctd\u003e1.875\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e1.500\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBushing Compatibility\u003c\/td\u003e\n\u003ctd\u003eClayton GIIRO Dual-Durometer or Clevite-Style Rubber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e1 Housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e1 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Dimensions\u003c\/td\u003e\n\u003ctd\u003e4\" x 4\" x 4\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eVerified Fitment (OFAS Standard)\u003c\/h3\u003e\u003cp\u003e✅ Fits 1997–2006 Jeep Wrangler TJ (SE, Sport, Sahara, X) — Front Upper Control Arm, Axle Side\u003cbr\u003e✅ Fits 2004–2006 Jeep Wrangler LJ Unlimited — Front Upper Control Arm, Axle Side\u003cbr\u003e✅ Fits 1993–1998 Jeep Grand Cherokee ZJ (Base, Laredo, Limited, SE, Orvis, TSi, 5.9 Limited) — Front Upper Control Arm, Axle Side\u003cbr\u003e❌ Does NOT fit Jeep Wrangler JK (2007–2018) — different UCA housing diameter and bracket spec\u003cbr\u003e❌ Does NOT fit Jeep Wrangler JL (2018–2026) — different UCA geometry\u003cbr\u003e❌ Does NOT fit Jeep Grand Cherokee WJ (1999–2004) — verify housing OD before ordering\u003cbr\u003e❌ Does NOT fit rear control arm positions — axle-side front upper mount only\u003c\/p\u003e\u003ch3\u003eInstallation \u0026amp; Fabrication Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHousing requires press-fit bushing installation — do not hammer bushing in without a proper bushing press or C-clamp press tool.\u003c\/li\u003e\n\u003cli\u003eVerify axle bracket ear width matches 1.500\" housing width before installation — shimming may be required on modified axle housings.\u003c\/li\u003e\n\u003cli\u003eWhen installing a GIIRO bushing: ensure the dual-durometer outer layer seats fully flush with the housing shoulder on both faces.\u003c\/li\u003e\n\u003cli\u003eWhen installing a Clevite-style rubber bushing: apply rubber lubricant (not petroleum-based) during press-in to prevent tearing.\u003c\/li\u003e\n\u003cli\u003eTorque axle-side UCA bolt to your specific Clayton arm specification — verify with Clayton's torque spec sheet for your kit.\u003c\/li\u003e\n\u003cli\u003eInspect housing bore for ovality or scoring before pressing in a new bushing — a worn bore will not retain the bushing under load.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWheel \u0026amp; Tire Fitment\u003c\/h3\u003e\u003cp\u003eBushing housing component — no direct wheel or tire fitment restriction.

Confirm your axle bracket ear spacing is 1.500\" and your bushing OD is 1.875\" before pressing.
