Steel/Alum U-Joint Assy Chevy/Chrysler

The Winters Steel/Aluminum U-Joint Assembly (Model 3700-2) is a heavy-duty drivetrain component designed for Chevrolet and Chrysler vehicles. It provides reliable power transmission from the transmission to the driveshaft, making it suitable for various applications, including towing, racing, and modified engine platforms.

This u-joint assembly is engineered to eliminate vibration, absorb drivetrain shock, and maintain smooth torque delivery under demanding conditions. Its dual-material construction of steel and aluminum balances weight savings with structural strength, reducing unsprung mass while ensuring the rigidity needed to handle torque spikes.

Ideal for street machines, restorations, and track-day vehicles, this assembly is compatible with Chevrolet small-block and big-block engines. Mechanics and enthusiasts appreciate its four-point cross design, which allows for articulation between misaligned shafts, accommodating suspension compression and extension cycles without binding or premature wear.
