Heavy-Duty 4WD Gear Coupling for Tractor Drive Applications SKU: QT403965

When your 4WD coupling fails, you lose the traction that keeps you moving through tough field conditions—leaving you stuck with only rear-wheel drive when you need all four wheels pulling. This heavy-duty gear coupling restores reliable torque transfer between drive components, ensuring smooth power delivery to maintain the traction and performance your operation demands.

Why This Coupling Delivers

• Hardened steel construction resists wear and fatigue under high-torque loads
• Precision machining ensures accurate alignment and reduces vibration
• Heavy-duty design withstands misalignment and shock loads common in farm work
• Direct replacement eliminates guesswork and fits existing drive components

When your 4WD won't engage properly or makes grinding noises during operation, this precision replacement eliminates slippage and restores the positive engagement these systems were built to deliver. S&H Parts has the experience to help you get the right coupling for your application.
