The Arma-Steel 30751 and 30745 Positraction Units are precision-engineered components designed specifically for 1956-62 Chevrolet Corvette 4-series vehicles. These units are renowned for their exceptional quality and durability, making them a top choice among classic car enthusiasts and restorers.

The Arma-Steel 4-series Positraction Unit is a critical component of your Corvette's drivetrain, responsible for delivering optimal power to the wheels while preventing wheel spin. The unit features a robust design, with heavy-duty gears and bearings that can withstand the rigors of high-performance driving. The Positraction system itself is a dual-cone design, providing positive traction in both forward and reverse gears.

The Arma-Steel 4-series Positraction Unit is also designed for easy installation, with clear installation instructions and all necessary hardware included.

Details:

Original Chevy 4-series positraction unit that can be used in 56-62 Corvettes and 56-64 full size cars. It can be used in a 55 Chevy car, but the axles have to trimmed at splinted end, as cars never had posi rear ends originally. I do also have a 3-series 56-64 posi unit that would sell for parts, as it is cracked in several places, but complete. Due to the late 1960 date, it may have been originally installed in a 61 Corvette or full size Chevy.
