The TeraFlex JK Front Big Brake Kit is designed as a factory brake upgrade for JK owners looking for a performance brake package that will handle the increased braking requirements needed after larger wheels and tires are used. The simple bolt-on upgrade installation requires no cutting, welding or adapter bracketry. The big brake kit features oversized 56mm dual piston calipers for increased clamping force and surface area. The 13.3” Mill-balanced vented rotor provides greater braking leverage to allow stopping distance to be decreased substantially and decreases heat buildup. The rotors also feature two wheel bolt patterns – 5×5″ and 5×5.5″. The Composite-resin, semi-metallic pads have excellent cold stopping power resulting in maximum initial speed scrub, increase pad life and reduce noise & dust. Note: A minimum of 17” diameter wheels must be run with the big brake kit.
The TeraFlex JK performance rear big rotor kit is the perfect upgrade for JK Wrangler owners requiring increased braking performance with larger tires. This kit allows the factory brake caliper and brake pads to be retained, while increasing the rotor diameter to 13.5”. The increased clamping distance from the rotor center results in greater braking leverage to allow stopping distance to be decreased substantially (larger rotor diameter = greater stopping power).
