Product Description
Six-lug rear disc-brake conversion kit for compatible 1961–1991 Chevrolet and GMC truck, SUV, Suburban, and van axle applications. Compatibility depends on lug pattern and axle-flange measurements—not model name alone.
Key Features
- Two 12-inch drilled/slotted rear rotors with 6 x 5.5-inch (6 x 139.7 mm) pattern
- Large-bore GM-style calipers with built-in parking-brake mechanisms
- Semi-metallic pads and pins
- Brake hoses and standard-length parking-brake cables
- Reference: DBK1012TRK-6
Fitment Note
Supplier-listed as potentially compatible with 1961–1987 Chevrolet C10/K10 and GMC 1000/C15/K15/K1500 pickups, plus selected 1961–1991 Chevrolet K5/K10 Blazer, Suburban and vans and GMC Jimmy, Suburban and vans. This kit is for six-lug—not five-lug—applications. Confirm axle housing, axle-flange dimensions, bolt pattern, bearing offset, rotor/caliper clearance, wheel diameter/backspacing, parking-brake routing, and hydraulic requirements before ordering.
Additional Parts Note
A four-wheel-disc combination valve or adjustable proportioning valve and a 1-1/8-inch-bore master cylinder are recommended by the supplier and are not included.
Installation & Safety Note
This is a major brake-system modification. Professional installation, hydraulic-system design, correct fasteners, line routing, bleeding, parking-brake adjustment, leak testing, and controlled low-speed verification are required before road use.
