GM Turbo 400 TH400 Billet Steel Intermediate Clutch Sprag-Outer Race
Product Information
Overview
Speedmaster heavy duty intermediate clutch outer race delivers more torque capacity of any OE race. High torque loads cause the race to fracture at two stress points: the radial lube holes that contact the rollers and the sharp inside corners at the base of the outer splines. Design improvements to the splines, plus upgraded material and a custom manufacturing process, further improve durability to make this heavy duty race the best option available for the TH400.
