4WD Shaft Coupler for New Holland T6000/T6/TSA Series Front Axle Drive SKU: QT43792
When 4WD splines wear or strip, you lose front wheel drive capability right when conditions demand it most—stuck in mud, climbing steep grades, or pulling heavy implements through tough ground. This precision 14-spline coupler restores full front axle power transfer, ensuring reliable 4WD engagement when maximum traction is critical.
Why This Part Matters
- Precision-machined 14 splines distribute torque loads across multiple contact points for maximum strength
- Heat-treated steel construction resists wear and prevents the stripping that sidelines tractors
- Exact specifications match original equipment for proper fit with mating driveline components
- Quality metallurgy handles shock loads without brittleness or premature failure
A worn coupler typically fails when you're stuck and need 4WD most, causing grinding noises during engagement or complete loss of front wheel power. With over 55 years of experience supplying critical tractor parts, S&H Parts has the expertise to help you get the right fit the first time.
