Stage-1 About: Raybestos Stage-1 Performance frictions are an affordable solution for performance applications that may not require the capacity of the Gen2 Blue Plate Special, but do require a friction plate that can handle the demands that a stock tan or high energy plate cannot. Stage-1 frictions are not limited to performance, but also enhance heavy duty applications by increasing holding capacity, while being able to withstand higher temperatures associated with towing heavy loads. Raybestos Stage-1 Performance frictions are the best choice for street rods, tuner cars and mild street strip applications. Advantages: · Withstands high horsepower · Greater torque capacity · Maintains piston travel · Optimum performance · Higher heat resistance · Smooth engagements · Enhanced shift feel All these Kits have Clutches Manufactured by Raybestos, and Gasket Sets Mfg by TRANSTEC.
