Mack E7 SS318 Compatibility
For Mack E7 SS318 engines, this new single-cylinder air compressor is listed under part numbers S-21436, 303GB5129AM, S9111530550X, and 303GB5129M.
Before ordering, we should confirm your engine’s model and application against the existing compressor and service records. Engine fitment depends on matching the correct assembly, so don’t rely on the engine family alone.

If your records show a different number, we should consult a qualified parts supplier or technician before installation. This listing specifies Mack E7 SS318 compatibility.
Detailed features
Beyond confirming fitment, we can assess the compressor’s listed specifications: DDTP Advance Performance identifies it as a single-cylinder unit, model 303GB5129M, with a painted exterior and a weight of 42 pounds. Its Cylinder Design gives us a clear description of the unit’s basic configuration, but the available listing doesn’t provide displacement, operating pressure, or airflow figures.
We should verify those details against the truck’s service requirements before installation. Performance Specifications also include manufacturer part number 303GB5129MD, which differs slightly from the item model number. We can use both identifiers when checking documentation, ordering the replacement, and confirming that the supplied compressor matches the intended application.
Pros and Cons
We’ll weigh this compressor’s fitment and listed specifications against the practical limits of the available product information.
Its Mack E7 SS318 compatibility and cross-reference numbers are clear, but warranty terms aren’t specified here.
Let’s compare the main pros and cons before deciding if it suits your needs.
Pros
The DDTP Advance Performance compressor offers a direct replacement option for Mack E7 SS318 engines, with listed cross-reference numbers S-21436, 303GB5129AM, S9111530550X, and 303GB5129M to help confirm fitment. We can use these identifiers to check compatibility against the existing unit before ordering.
Its single-cylinder design provides a straightforward replacement configuration for the specified engine. The Durable painted exterior gives us a finished surface, while the 42 pound construction offers a clear weight reference for handling and installation planning.
DDTP lists model number 303GB5129M and manufacturer part number 303GB5129MD, giving us additional details to verify the compressor matches our application.
Cons
Although the listing identifies this compressor for Mack E7 SS318 engines, it provides limited technical detail beyond its single-cylinder design, 42-pound weight, and painted exterior. We don’t get airflow, operating-pressure, or duty-cycle figures, so we can’t confirm whether it meets a particular truck’s demands without checking with the seller or comparing the original unit.
The listing also doesn’t explain installation requirements or included hardware. At 42 pounds, handling may take extra care during positioning, especially in a tight engine compartment. The painted finish offers little information about corrosion protection or long-term durability, so we’d verify those details before purchase.
Concluding thoughts
For Mack E7 SS318 engines, this new single-cylinder compressor is a practical replacement option, with listed cross-reference numbers including S-21436 and 303GB5129M. We’d also verify the other listed references—303GB5129AM and S9111530550X—against the existing unit before ordering.
At 42 pounds, it’s a substantial component, so plan safe handling and check fitment, connections, and mounting during installation. Its painted exterior and DDTP branding provide basic product details, but the available information doesn’t establish performance or long term reliability.
Review installation considerations, warranty terms, and return eligibility before purchase. If the numbers match your application, this compressor merits consideration as a replacement.
