Product Details

The Raybestos R-Line 2037R is a brake drum replacement for vehicles that use a 5-lug rear drum brake design. Its dimensions are important for maintaining correct shoe-to-drum contact, pedal feel, and braking balance. The outer cooling fins add a thermal-management feature that can help the drum shed heat more effectively during repeated stops.

Raybestos R-Line focuses on practical replacement parts for everyday brake service, and this drum follows that approach with application-specific sizing and a conventional service-part design. If you are replacing a worn or heat-affected drum on a Chevrolet C10, GMC C10, or another listed interchange application, the 2037R provides a direct-format solution. This part cross-references Centric Parts 123.62005 and AP Exhaust 20056 for the same application.

What It Helps Address

• Brake pulsation caused by an out-of-round or worn drum
• Reduced braking consistency from heat buildup
• Grooving or scoring on the drum surface
• Noise from uneven shoe-to-drum contact
• Service issues on rear drum brake systems with 5-lug mounting

Installation Notes

Verify drum diameter, depth, lug hole count, and lug hole diameter before installation. Inspect brake shoes, wheel cylinders, and hardware condition at the same time so the new drum is not installed over worn components. Clean the friction surface before assembly and confirm the drum seats correctly on the hub.

For fitment-based searches, this brake drum is referenced for Chevrolet C10 and GMC C10 applications through interchange data. Confirm the exact vehicle configuration against the original drum dimensions before ordering the Raybestos 2037R.
