Description

This unit is upgraded with a Sure Grip clutch-type limited slip differential for maximum performance and reliability. It features a nodular iron case for improved rigidity, power handling, and reduced deflection, ensuring consistent gear contact and long service life. This assembly includes a Sure-Grip/Powr-Lok limited slip differential with a four-spider-gear design to improve torque bias and traction.
