Description

The Baer Brakes 15" Extreme+ Rear Brake Kit (Part #4302421R) is a high-performance brake system designed for the rear axle of compatible GM 1500 series trucks and SUVs. It features a 1-piece Monoblock 6-piston 6S caliper, CNC machined from a US-sourced 2618 aluminum forging. The calipers are powder-coated red and include stainless steel pistons, abutments, D.O.T. compliant dust and weather seals. The kit utilizes the popular D1247 pad type. The rotors are 15-inch, 2-piece, slotted, drilled, and zinc-plated, pre-assembled with NAS high-grade stainless hardware. All necessary brackets and hardware are included for installation. This system is designed for vehicles with OE rear disc brakes and a manual park brake and requires a minimum wheel diameter of 19 inches. It does not fit vehicles with drum brake rear ends or electric park brakes.
