702 Horsepower Needs Front Brakes That Can Keep Up
The Ram 1500 TRX makes 702 supercharged horsepower and the factory front brakes are working hard to keep that power in check. The RFK.590.07 Rotora Street Challenge Front Brake System replaces the stock front setup with an 8-piston RF802 forged aluminum caliper and 405x36mm 2-piece floating rotor, giving TRX owners the front braking confidence the truck demands on the street and in the desert.
Key Features

- 405x36mm 2-piece floating disc for reduced weight and improved heat dissipation
- Direct bolt-on fitment for the front axle, no permanent modification required
- Available in 10 caliper finishes including Natural Anodize (Zinc)
- Slotted or Drilled rotor face options to match braking preference
- Stainless steel braided brake lines included for firmer pedal feel
