Pro Performance 13in Rear Big Brake Kit | 1988-1998 Chevy/GMC Truck & SUV

A pro-level 13" rear big brake kit for 1988-1998 Chevy/GMC full-size trucks and SUVs that uses a true truck rotor — no machining of your axle or rotor required. The integrated Mustang caliper includes a working parking brake, but the kit functions fine even without it hooked up.

What You Get

• Brand-new Mustang caliper (not rebuilt)
• 13" 1-piece rotor, drilled/slotted/zinc plated with directional vanes (1.1" thick)
• 5x5 bolt pattern
• Laser-cut, zinc-plated caliper mounting bracket
• Stainless steel hoses and all necessary hardware
• Brake pads

Before You Order

You must measure your axle housing bolt pattern and axle offset before ordering — these trucks ran several different rear ends across the years, so confirming fitment up front saves a return trip. Choose between the 10" drum-brake axle option (fits 10-bolt and 14-bolt 454SS axles) or the 9" Ford option (Torino housing end, 2.5" axle offset).

Caliper offset is negative, so this kit clears most 18" wheels and larger with no fuss, and plays especially well with aftermarket wheel offsets. Add the e-brake cable adapter if your parking brake setup needs it.

Pair this with our Pro Performance 14" Front Big Brake Kit to finish the whole truck in one order. These kits typically ship within 3-5 days.
