Detailed Description

DuraGo BD8988 is a rear brake drum engineered for vehicles that use a 9.5-inch nominal drum size and a 5-lug rear brake setup. It is a strong match for long-tail searches such as rear brake drum for 1992-2003 Chevrolet S10, rear drum replacement for 1992-2003 GMC Sonoma, and rear brake drum for 1993-1997 Pontiac Firebird. The cast iron / steel top design supports stable braking performance, while the outer cooling fins help manage heat during repeated stops. This part cross-references Anchor 8988 and Hayden 2585 for the same application.

What It Helps Address

• Rear brake drum wear from normal mileage and heat cycling

• Reduced braking consistency from drum distortion or scoring
• Fitment issues on rear drum brake service for 5-lug applications
• Heat buildup during repeated stop-and-go driving

Installation Notes and Tips

Verify drum diameter, bolt circle, center hole, and brake surface width before installation. Inspect rear shoes, hardware, and wheel cylinders at the same time so the new drum seats against a clean, even braking surface. Confirm rear-only fitment for the listed Chevrolet, GMC, Isuzu, Oldsmobile, and Pontiac applications before service.
