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. MaxPaks feature Stage-1 friction and steel reaction plates with added capacity compared to the OE design. MaxPaks may also include kolene steels, steel pressure plates, and snap rings depending upon the application. The contents of these MaxPaks will allow you to increase the friction plate capacity. The additional capacity not only increases clutch pack performance and durability but also offers more resiliency in addition to significant increase in torque holding ability. This is a the strongest most professional kit of its class if you are doing any kind of towing or have lots of horse power this is the kit for you! Raybestos Stage-1 Performance frictions are the best choice for street rods, tuner cars and mild street strip applications.
