The same proven technology that created the Strange S-Trac for Ford 9 inch rear ends, is available for Ford 8.8 inch rear ends.

There is little question that the Ford 8.8 inch rear end housing is capable of handling large amounts of horsepower when assembled with the correct parts. Strange Engineering is taking things to the next level with the introduction of the S-Trac 35 spline 8.8 differential. The torque biasing S-Trac is purely mechanical which eliminates the need for clutches. It provides quiet operation while maximizing tire traction and vehicle acceleration.

Helical Gear Differential

The foundation of the S-Trac is the heat treated forged 8620 case that creates a light, durable, and rigid unit. The helical cut gears are manufactured from 9310 steel, heat treated and coated with a dry film solid lubricant providing exceptional strength and minimizes wear. The seamless operation of the Strange S-Trac makes it ideal for street, strip, road racing and autocross. This premium unit includes Timken carrier bearings with races, side shims, and a lifetime replacement warranty to the original purchaser.
