What is the benefit of 4-piston calipers over stock calipers?

Four-piston calipers distribute clamping force more evenly across the larger rotor surface. This helps reduce heat buildup and fade during hard braking situations compared to smaller factory calipers.

Does this kit include everything needed for installation?

Yes, the kit includes Alcon 4-piston rear calipers, 355x22mm vented rear rotors, brake lines, and mounting hardware for a complete rear brake upgrade.

Will this kit fit my Jeep JK if it has aftermarket wheels?

This kit is designed for the factory hub and mounting points. Compatibility with aftermarket wheels depends on their specific design and clearance around the larger caliper and rotor.
