Part Number



The TeraFlex JK/JKU Front Big Brake Kit is a must for JK Wrangler and JKU Wrangler Unlimited models requiring increased braking performance with oversized - and heavier - wheels and 33-35 inch tires. This simple bolt-on upgrade doesn't require cutting, welding, or adapters.


  • Improved braking performance over factory brake system
  • Oversized 56mm (2.2 inch) dual-piston calipers for increased clamping force and surface area
  • Larger 13.3 inch (338mm) rotors for superior stopping performance - stock is 11.9 inch (302mm)
  • Slotted rotors offer better heat dissipation than smooth rotors
  • Mill-balanced vented rotors for maximum heat dissipation
  • Rotors feature dual bolt patterns - 5 x 5 inch and 5 x 5.5 inch
  • Composite-resin, semi-metallic pads have excellent cold-stopping power for maximum initial speed scrub w/ increased pad life and reduce noise and dust
  • 100 percent bolt-on upgrade for easy installation
