We have been asked for a 2.5-ton pinion brake kit that has a little more bling and contains everything you need without having to go out and get your own caliper. This is it! This setup comes with the rotor, the Wilwood caliper, high performance pads and all the brackets and hardware. The caliper can be clocked into four different positions: 1:00, 3:00, 9:00, 11:00. (3:00 and 9:00 shown.) The Wilwood caliper uses a 1/8" NPT female inlet port. We sell an adapter to make it -3AN male if you are using AN lines. The Wilwood caliper is the same for all 4 mounting positions, no more worries about getting the correct side caliper.
