Teraflex 4303400 Front Big Brake Kit for 07-18 Jeep Wrangler JK This front JK Big Brake kit includes: The TeraFlex front JK 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 oversized twin-piston brake caliper provides for more clamping force, with an increased surface area while decreasing brake fade. The oversized caliper will provide a more efficient method of heat dissipation for increased stopping power. The optimized high-performance brake pads provide maximum surface area and reduce brake dust and noise during extreme braking. The composite-resin, semi-metallic pads increase the lifetime of the brake system. An OEM factory styled anchor bracket holds the oversized caliper in proper alignment to the rotor, and eliminates extra movement and flex in the system. Durable automotive silver zinc plating is resistant to corrosion. High-performance 13.3” mill-balanced vented rotors keep the braking system cool for maximum stopping in all conditions. The dual wheel bolt pattern allows for use on multiple wheel applications. A premium e-coat finish is durable and resists rust.
