Description

The Eaton 913A315 Detroit Truetrac is a helical-gear style limited-slip differential designed to maximize wheel traction and enhance driving. It is maintenance-free, requires no special lubrication or friction modifiers, and offers lifetime torque bias retention. It features a simple, proven design for smooth and quiet operation, limiting wheel spin-out and improving handling by performing as an open differential until needed.
