These inserts are used in the fabrication and repair of heavy-duty adjustable control arms and suspension links where a threaded rod end needs to be installed into a larger, heavier-wall square tube. The 2\"x2\" 1\/4\" wall tube is a heavier construction than the 1.5\"x1.5\" 1\/8\" wall tube — used in applications requiring greater structural strength, such as long arm lower control arms or high-stress link positions. The CNC machining ensures a precise press fit into the tube ID. Clayton presses these in with a hydraulic ram in production; a 5 lb sledge hammer is sufficient for field or shop installation. After pressing, verify the insert is square to the tube axis before welding — a cocked insert will cause thread misalignment and binding at the rod end. Fully weld the insert after confirming square. \u003cstrong\u003eThis SKU is right-hand thread only\u003c\/strong\u003e — if you need left-hand thread for the adjuster end of the same arm, order the appropriate LH SKU separately.\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-2300213\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Spec\u003c\/td\u003e\n\u003ctd\u003e1.25\"x12 Right-Hand (RH) — RH ONLY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Tubing\u003c\/td\u003e\n\u003ctd\u003e2\"x2\" square tubing, 1\/4\" wall\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFit Type\u003c\/td\u003e\n\u003ctd\u003eCNC-machined press fit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation Method\u003c\/td\u003e\n\u003ctd\u003eHydraulic ram or 5 lb sledge hammer; fully weld after pressing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread Hand\u003c\/td\u003e\n\u003ctd\u003eRight-Hand only — for fixed\/chassis end of control arm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\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\" L x 4\" W x 4\" H\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\u003cstrong\u003eCompatible With:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e✅ 2\"x2\" square tubing — 1\/4\" wall thickness only\u003c\/li\u003e\n\u003cli\u003e✅ Any adjustable control arm or suspension link fabricated to this tube spec\u003c\/li\u003e\n\u003cli\u003e✅ 1.25\"x12 right-hand threaded rod ends and adjusters\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eDoes NOT Fit:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e❌ 1.5\"x1.5\" 1\/8\" wall square tubing — different tube ID; see COR-2300222 (1\"x14 LH, 1.5\" tube)\u003c\/li\u003e\n\u003cli\u003e❌ Round DOM tubing — this insert is machined for square tube ID geometry only\u003c\/li\u003e\n\u003cli\u003e❌ 1.25\"x12 left-hand (LH) applications — this is a right-hand thread insert only; verify thread hand before ordering\u003c\/li\u003e\n\u003cli\u003e❌ 2\" square tubing with wall thickness other than 1\/4\" — tube ID will differ and press fit will not be correct\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation \u0026amp; Fabrication Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConfirm tube ID matches the insert OD before pressing — this insert is machined for 2\"x2\" 1\/4\" wall square tubing specifically.\u003c\/li\u003e\n\u003cli\u003ePress insert into tube using a hydraulic ram or 5 lb sledge hammer — drive evenly to avoid cocking the insert during installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVerify the insert is square to the tube axis before welding\u003c\/strong\u003e — use a square or straight edge to confirm alignment.
