Dorman 924-5809 Air Brake Reservoir

Dorman 924-5809 Air Brake Reservoir

Dorman 924-5809 is a direct replacement air brake reservoir for air-actuated braking and suspension systems. It is built from carbon steel with a black finish and OE-style port layout to match the original tank configuration.

For commercial truck and bus applications, this air tank supports stable air storage where corrosion or leakage has compromised the original reservoir. It is a practical replacement for vehicles that need a 53 L, 2-chamber air reservoir rated to 150 PSI.

Key Features

• Carbon steel construction with 0.13 in material thickness
• 11.25 in diameter and 34.8 in length
• 53 L volume for air-actuated braking and suspension systems
• Two-chamber tank design
• Maximum working pressure: 150 PSI
• Strap-on mounting style
• 11 port openings with OE-style port configurations
• Black finish for a clean replacement appearance

Detailed Description

This Dorman air brake reservoir is engineered as an OE-style replacement for a corroded or leaking air tank. The port arrangement is designed to match the original equipment tank, helping maintain proper routing for air brake and suspension lines. For fleet maintenance and repair work, Dorman 924-5809 provides a straightforward replacement option when the original reservoir no longer holds pressure or shows visible rust damage.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is a relevant replacement choice for heavy-duty vehicle service where air storage integrity matters, including applications tied to Freightliner and International truck platforms.

What It Helps Fix

• Air leaks caused by a corroded reservoir
• Reduced air pressure retention in braking systems
• Rust damage on the original air tank
• Air suspension performance issues related to tank failure
• Port mismatch during reservoir replacement on Freightliner or International applications

Installation Notes and Tips

Verify port thread sizes, chamber layout, diameter, and overall length before installation. This reservoir uses strap-on mounting and does not include mounting hardware, so reuse or source the correct straps and related components separately. Confirm line routing and port orientation against the original tank before tightening connections.

Because fitment data is not provided, confirm compatibility by matching the original reservoir dimensions and port configuration on your Freightliner or International vehicle before ordering.

Quality Assurance

Dorman replacement parts are built to match original equipment form and function where specified. Part number 924-5809 is manufactured as a direct-fit style air reservoir with the same port configuration approach as the original tank.
