    Crown Automotive RT31058 Features:

    RT Off-Road's Front & Rear 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 Front Calipers with a pair of 54mm pistons for increased clamping forces, resulting in increased piston area over the single piston calipers. The 13" vented Front Brake Rotors give the braking system greater leverage. The rear brakes are upgraded with an oversized Rear Caliper Bracket and a 13.5" Rear Rotor for increased leverage, resulting in increased piston area over the factory caliper bracket. A 17" wheel is required. Brake Master Cylinder (Replaces Part #: 68091278AB) is also suggested for better brake pedal feel and greater braking performance.
