Dorman 924-5811 Air Brake Reservoir
Dorman 924-5811 Air Brake Reservoir
Dorman 924-5811 is a direct-style air brake reservoir for air-actuated braking and suspension systems. It replaces a corroded or leaking tank with an OE-shaped reservoir that uses the same port configuration for service on heavy-duty truck and commercial vehicle applications.
- Carbon steel construction with black finish
- 30 L volume with two-chamber tank design
- 8.5 in. diameter and 33 in. length
- Maximum working pressure: 150 PSI
- Strap-on mounting style
- 10 ports with M22 and 1/4 in. thread sizes
- Replacement air tank for brake and suspension air systems
OE-Style Replacement Details
This air brake reservoir is built to match the original tank layout, including port placement and thread configuration, so it can be selected for service work where the existing reservoir has rust, leakage, or pressure loss. The Dorman 924-5811 is a practical replacement for commercial vehicles that rely on stable air supply for braking performance and suspension operation. This part cross-references 3829915C1 for the same application.
What It Helps Fix
- Air loss caused by tank corrosion or pinholes
- Reduced brake system pressure from a leaking reservoir
- Suspension air supply issues tied to a damaged tank
- Service downtime from a cracked or deteriorated air chamber
- Fitment problems when replacing an OE-style reservoir with the same port layout
Installation Notes
Verify tank diameter, length, port count, thread sizes, and mounting style before installation. This reservoir uses strap-on mounting and does not include mounting hardware, valves, or threaded mounting brackets. Confirm the vehicle’s air system configuration and port requirements before replacing the original tank on compatible truck or commercial vehicle applications.
Quality Assurance
Dorman manufactures replacement components to match original equipment dimensions and service requirements. This reservoir is intended as a direct-style service part for air brake and suspension systems where the original tank has failed due to corrosion or leakage.
