Strange Engineering 35 Spline Ford 8.8 Helical Differential w/Special Side Bearings, Races, and Shims
The Strange 35 Spline S-Trac for Ford 8.8 rears is a helical gear differential that offers smooth and progressive power transfer. It's superior design and quality make it ideal for the most abusive Street/Track applications.
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. The forged steel case halves are heat treated and fully machined to minimize weight and provide a rigid mounting surface for the ring gear, resulting in improved gear life. Internal gear pocket geometry is designed to minimize stress risers increasing component life.
The housing encapsulates precision manufactured gears, including 9310 steel pinion gears that provide exceptional strength. All internal gears, pinion and side gears, are vacuum heat treated to increase strength and also cold treated to extend service life while reducing wear. A dry film solid lubricant coating is applied to friction surfaces to minimize wear.
The S-Trac is recommended for full bodied street/track cars that run the 1/4 mile in the low 9 seconds or slower. For Drag Race Only vehicles, Strange Engineering strongly recommends using a spool. The seamless operation make it also ideal for Road Racing, Off-Road and Autocross. This premium unit carries a limited lifetime replacement warranty to the original purchaser.
