Mack RD Truck Air Tanks, Wraps & Mounting

Frequently Asked Questions About Mack RD Truck Air Tanks, Wraps & Mounting

Will an air tank designed for a Mack RD fit my specific truck configuration?

Mack RD trucks were built over many years with different frame lengths, chassis setups, and air system layouts, so tank size, mounting bolt patterns, and port locations can vary. Always check the dimensions, mounting hole spacing, and port configuration against your existing tank before ordering, and reach out to our team with your VIN or truck details if you are unsure.

What is an air tank "wrap" and do I need one?

A wrap is a decorative or protective cover that fits around the air tank, often used to dress up the exterior of the truck or add a bit of extra corrosion protection to the tank surface. Wraps are not required for the air system to function, but they are a popular upgrade for owner-operators who want a cleaner, more finished look under the truck.

What materials and finishes are available for tanks and wraps?

Air tanks are typically steel or aluminum, while wraps are commonly offered in stainless steel with polished, brushed, or diamond-plate finishes. Steel tanks are durable and budget-friendly, aluminum tanks weigh less, and stainless wraps resist corrosion and hold up well to road grime and washing.

What mounting hardware is included, and will I need extra brackets or straps?

Most tanks and wraps ship with the basic mounting hardware needed for a direct replacement, but this can vary by product and manufacturer. If your existing brackets, straps, or mounting bars are worn, rusted, or missing, you may need to order these separately to complete a secure installation.

Can I install an air tank or wrap myself, or do I need a professional?

Many owner-operators and shop technicians replace air tanks and install wraps themselves, since the process generally involves disconnecting air lines, unbolting the old tank, and mounting the new one or its wrap. That said, air tanks are part of your truck's brake and air system, so if you are not comfortable working with air lines and fittings, it is best to have a qualified technician handle the installation and verify there are no leaks before returning to the road.
