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
