14-Spline 4WD Drive Coupling for Fiat 100-90 Late Series and Case MXM Tractors SKU: QT7507

When your 4WD coupling fails, you lose traction exactly when you need it most—during heavy fieldwork, wet conditions, or steep slopes. A worn or damaged coupling creates dangerous wheel slip, uneven tire wear, and puts excessive strain on your transmission. This 14-spline replacement restores proper power transfer between front and rear axles.

Key Benefits

• Heavy-duty materials built for high-torque 4WD applications
• Precision-cut 14 splines ensure full engagement without damaging play
• Exact-fit replacement eliminates guesswork and premature failure
• Restores factory-spec power transfer for maximum traction

Professional mechanics know that 4WD system repairs require precision parts. This coupling's exact spline tolerances and robust construction prevent the binding, vibration, and premature wear that plague aftermarket alternatives. When your livelihood depends on getting through muddy fields or up steep hillsides, this is the part that keeps you moving.
