Alcon introduced the Jeep Wrangler JK Big Brake Kit because a lot of owners were looking for a huge upgrade in braking performance and some features not found in any other kits on the market. High-temperature seals as used in motorsports applications, dust seals for performance in the worst conditions, and a low profile designed to fit under your OEM wheels are what puts Alcon on top. These kits include everything you need including lines, hardware, and performance brake pads! The kit is compatible with your stock master cylinder and parking brake.
