Front Big Brake Kit with 13" Vented Rotors & Dual Piston Calipers
  • For 2007-2018 Jeep JK Wrangler

    Crown Automotive RT31046 Features:

    RT Off-Road's Front 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" vented 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.

      RT Off-Road's performance brake kits include everything you need to upgrade your OEM brakes to a high-performance option. These components assist in reducing the strain on your braking system as a result of larger wheel/tire combinations or when descending steep inclines. Kits can be bolted on without the need for cutting or welding, resulting in a seamless factory appearance.
