4WD Coupling Bolt for Ford 40 Series and TS Series Tractors SKU: QT409792

When your 4WD coupling fails, you lose the traction needed for demanding field conditions—whether you're pulling through mud, working steep slopes, or need extra grip for heavy implements. This is a direct bolt-on replacement that secures the coupling assembly in Ford 40 Series and TS Series 4WD systems, restoring reliable power transfer to your front axle.

Why This Part Matters

• Critical fastener that keeps your 4WD coupling properly aligned and engaged
• Prevents coupling slippage that causes grinding noises and power loss
• Heavy-duty construction withstands the high torque loads of 4WD operation
• Exact-fit design eliminates the guesswork of finding the right bolt specification

Installation requires proper alignment to prevent binding, and you'll want to ensure full engagement when assembled since partial engagement causes rapid failure. This bolt works with coupler part 404894 to complete your 4WD system repair. Since 1969, S&H Parts has helped farmers keep their 4WD systems working when traction matters most.
