• TeraFlex Jeep Wrangler JK/JKU Rear Performance Slotted Big Rotor Kit - Left and Right Brakes


    The TeraFlex JK/JKU Rear Performance Slotted Big Rotor Kit is an affordable upgrade 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 or welding. You will need to purchase OEM or aftermarket JK rear brake pads since this kit relocates and reuses the OEM calipers.
