Stop A Loaded Half Ton Truck Like It Owes You Money
Factory brakes on a 2013 to 2018 RAM 1500 4x4 were never built for a truck hauling a trailer or running heavy aftermarket wheels and tires. The Wilwood 140-18207 TX6R front kit swaps in forged aluminum six piston calipers and 16.00in GT directional vane rotors that shed heat fast and keep pedal feel consistent even after repeated hard stops. This is a direct bolt on upgrade engineered around the factory spindle and hub, so there is no cutting, drilling, or custom fabrication required.
Key Features
- Forged aluminum TX6R six piston calipers with internal bore seals for consistent clamping force
- 16.00in diameter Spec37 alloy GT directional vane rotors for high heat capacity and fade resistance
- Two piece rotor design with weight saving aluminum hats
- Radial mount caliper brackets bolt directly to the factory spindle, no modification needed
- BP-20 compound SmartPads tuned for heavy load stopping power and long wear
- Fully compatible with OE master cylinder output, ABS, and all factory electronic controls
- Includes DOT approved stainless steel flexlines and premium grade mounting hardware
- Black powder coat caliper finish
