Product Details

Important Notes:

  • No cutting, welding, or spacers required
  • Larger bore brake master cylinder 68091278AB also suggested for better brake pedal feel and improved braking performance


RT Off-Road's Big Brake Kit is the solution to the strain that oversized wheels and tires place on the braking system on any JK Wrangler. This Brake Kit features Calipers with a pair of 54mm pistons for increased clamping forces, resulting in increased piston area over the single piston calipers. The 13" drilled & slotted Brake Rotors give the braking system greater leverage. The end result of the Big Brake Kit when compared to OE brakes is a 22% shorter 60-0 distance! A 17" wheel is required. Brake Master Cylinder (Replaces Part #: 68091278AB) is also suggested for better brake pedal feel and greater braking performance.
