Clayton Off Road Premium CNC Tube Insert 1"x14 RH for 1.5"x1.5" 1/8" Wall Square Tubing

Is This for You?

• You're building or repairing a control arm or suspension link using 1.5"x1.5" 1/8" wall square tubing and need a 1"x14 right-hand threaded insert for the fixed or chassis-side end of the arm. This insert is CNC machined for a press fit into that specific tube size — not a universal weld bung.
• You need right-hand thread specifically at this position. The RH insert (COR-2300212) is the companion to the LH insert (COR-2300222) — a complete adjustable arm in 1.5" tube uses one of each. Confirm your thread hand before ordering.
• You're building to Clayton Off Road's control arm tube standards and need matching hardware for the 1.5"x1.5" 1/8" wall tube system. For the heavier 2"x2" 1/4" wall tube, see COR-2300213 (1.25"x12 RH).

The Result

• CNC-machined for precise press fit — machined to the ID of 1.5"x1.5" 1/8" wall square tubing; no filing, grinding, or gap-filling required before pressing in.
• 1"x14 right-hand thread — matches standard right-hand threaded rod ends used in adjustable control arm fabrication; right-hand thread is standard for the fixed or chassis-side end of an adjustable arm.
• Press-fit installation, weld to finish — press in with a hydraulic ram or 5 lb sledge, verify square alignment, then fully weld the insert to the tube for a permanent, structural connection.

The COR-2300212 is Clayton Off Road's premium CNC-machined tube insert for 1.5"x1.5" 1/8" wall square tubing, threaded 1"x14 right-hand. This is the right-hand companion to COR-2300222 (1"x14 LH, same tube size) — a complete adjustable control arm in 1.5" square tube uses one RH insert at the fixed/chassis end and one LH insert at the adjuster end. 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.

Audit Table

Verified Fitment (OFAS Standard)

Compatible With:

• ✅ 1.5"x1.5" square tubing — 1/8" wall thickness only
• ✅ Any adjustable control arm or suspension link fabricated to this tube spec
• ✅ 1"x14 right-hand threaded rod ends and adjusters

Does NOT Fit:

• ❌ 2"x2" 1/4" wall square tubing — different tube ID; see COR-2300213 (1.25"x12 RH, 2" tube)
• ❌ Round DOM tubing — this insert is machined for square tube ID geometry only
• ❌ 1"x14 left-hand (LH) applications — this is a right-hand thread insert; for LH see COR-2300222
• ❌ 1.5" square tubing with wall thickness other than 1/8" — tube ID will differ and press fit will not be correct

Installation & Fabrication Notes

• Confirm tube ID matches the insert OD before pressing — this insert is machined for 1.5"x1.5" 1/8" wall square tubing specifically.
• Press insert into tube using a hydraulic ram or 5 lb sledge hammer — drive evenly to avoid cocking the insert during installation.
• Verify the insert is square to the tube axis before welding — use a square or straight edge to confirm alignment. A cocked insert will cause thread misalignment and binding at the rod end under load.
• Fully weld the insert to the tube after confirming square — do not rely on press fit alone for structural use.
• Allow weld to cool fully before threading in rod end or adjuster — heat distortion can affect thread engagement.
• For a complete adjustable arm in 1.5" tube: use COR-2300212 (RH) at the fixed/chassis end and COR-2300222 (LH) at the adjuster end.

Wheel & Tire Fitment

Not applicable — this is a fabrication component. Fitment is determined by tube size and thread spec, not vehicle wheel or tire selection.

Engineering Question: Are you working with 1.5"x1.5" 1/8" wall square tubing, and do you need right-hand thread at this position? Confirm your tube wall thickness and thread hand before ordering. For a complete adjustable arm in 1.5" tube, you need both COR-2300212 (RH, this SKU) and COR-2300222 (LH) — one at each end.
