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” tires. This simple bolt-on upgrade doesn’t require cutting, welding, or adapters.

This kit fits both 2door and 4door JK Wrangles

• Front driver slotted brake rotor (# 4303412)
• Front passenger slotted brake rotor (# 4303411)


• Improved braking performance over factory brake system
• Oversized 56mm (2.2”) dual-piston calipers for increased clamping force & surface area
• Larger 13.3” (338mm) rotors for superior stopping performance – stock is 11.9” (302mm)
• Slotted rotors offer better heat dissipation than smooth rotors
• Mill-balanced vented rotors for maximum heat dissipation
