Crown Automotive RT31057 Rear Big Brake Kit for 07-18 Jeep Wrangler JK

Quadratec Part #: 56215-1047
Crown Automotive Part #: RT31057
Description
The Crown Automotive Rear Big Brake Kit is made as a simple upgrade for the JK Wrangler. Whatever the reason, when you need more stopping power this kit delivers by hanging a higher positioned bracket allowing for larger rotors. These brackets relocate the factory calipers up to clear for the 13.5" rotors. Larger rotors deliver better stopping power through their ability to resist thermal fading when under high demands. If your brakes feel slushy after being used aggressively then this kit is for you.
