GMC General Truck Air Tanks, Wraps & Mounting

Frequently Asked Questions About GMC General Truck Air Tanks, Wraps & Mounting

What is included in this category?

This category covers air tanks (also called air reservoirs) for GMC general trucks, along with the tank wraps that protect them from road debris and corrosion, and the mounting brackets or straps used to secure the tanks to the frame. These components work together to store compressed air for your truck's brake system and other air-powered accessories.

How do I know which air tank size or mounting style fits my truck?

Air tank size and mounting configuration depend on your truck's frame dimensions, existing tank layout, and the air system capacity your setup requires. Before ordering, measure your current tank or check your GMC's specifications, and compare those measurements against the listed dimensions and mounting hole patterns for each product. If you're replacing an existing tank, matching the original size and mounting style is usually the simplest approach.

Why use a wrap on an air tank, and what materials are available?

A tank wrap adds a layer of protection against rock chips, road salt, and general wear that can lead to rust or pitting on the tank's surface over time. Wraps are typically available in materials like diamond plate aluminum or stainless steel, and some are offered in polished or brushed finishes to match the rest of your truck's appearance.

Are these tanks and mounts DOT compliant for use with my brake system?

Air tanks used in the brake system are subject to DOT and FMVSS regulations regarding capacity, drain valves, and safety markings. Always confirm that any replacement tank meets the same air capacity and safety standards as your original equipment, and consult your truck's specifications or a qualified technician if you're unsure whether a specific tank is appropriate for your application.

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

Basic wrap installation is generally straightforward and can often be done with common hand tools. However, mounting or replacing an air tank involves working with the truck's air brake system, which affects vehicle safety. If you're not experienced with air brake components, we recommend having the installation performed or at least inspected by a qualified technician to ensure proper fitment, secure mounting, and leak-free connections.
