Crown Automotive RT31057 Rear Big Brake Kit JK


Part Number: RT31057


  • Fits 2007 to 2018 JK Wrangler and Rubicon
  • 2-door models and 4-door models

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.

This Kit includes:

  • 2 Caliper Brackets
  • 2 Slotted Rotors
  • 4 Brake Pads
  • 1 Caliper Pin Kit
  • 1 Grease Packet

Product Notes:

Rear Big Brake Kit only Works with 17″ Wheels or Larger; 13.5″ Diameter Rotors; Rotors feature a 5 on 5″ and 5 on 5.5″ Bolt Pattern.
