4WD Front Axle Coupling for Fiat 100-90 Early Series and Compatible Ford/Case Models SKU: QT7587

When your 4WD coupling starts grinding, slipping, or fails to engage entirely, you lose the front-wheel traction that makes the difference between getting stuck and getting work done. This 12-spline front axle coupling restores positive 4WD engagement to your early Fiat 100-90 tractor, delivering the reliable four-wheel drive power transfer you need for demanding field conditions and heavy implement work.

Why Quality Components Matter

• Precision-cut 12 splines ensure exact fit without the play that causes rapid wear
• Heavy-duty construction handles high-torque demands of 4WD applications
• Proper heat treatment provides durability while preventing brittle failure under shock loads
• Exact OEM specifications maintain proper drivetrain alignment and operation

When your front axle won't engage or makes noise during operation, this coupling eliminates the slippage and restores the traction control these tractors were engineered to deliver. Our 55+ years of experience means we understand the critical role this component plays in maintaining productive operation during challenging conditions.
