Sterling Acterra Truck Air Tanks, Wraps & Mounting

Frequently Asked Questions About Sterling Acterra Truck Air Tanks, Wraps & Mounting

What do air tanks, wraps, and mounting brackets do on my Sterling Acterra?

Air tanks store compressed air used by the truck's air brake system, suspension, and other pneumatic components. Wraps are protective covers that shield the tanks from road debris, moisture, and corrosion, while mounting brackets and straps secure the tanks firmly to the frame. Together, these parts keep your air system running safely and reduce wear caused by vibration and exposure to the elements.

Will these air tanks and mounting parts fit my specific Sterling Acterra model year?

Sterling Acterra trucks were produced across several years with variations in frame layout and air system configuration, so tank size, mounting hole spacing, and bracket style can differ. Always check the listed specifications, including tank capacity, dimensions, and mounting pattern, against your truck's original equipment before ordering. If you're unsure, having your VIN or the part number from your existing tank on hand will help confirm a proper fit.

What material and finish options are available for air tank wraps?

Air tank wraps are typically available in polished aluminum or stainless steel finishes. Polished finishes offer a clean, reflective look but require periodic care to prevent oxidation, while brushed or textured finishes tend to hide minor scratches and road grime better over time. Choosing the right finish often comes down to matching the rest of your truck's exterior styling and how much maintenance you're willing to put in.

Can I install a new air tank or wrap myself, or should I have a professional do it?

Basic wraps and mounting straps can often be installed with common hand tools if you're comfortable working underneath the truck and following the included instructions. However, replacing an actual air tank involves working with a pressurized air system, so it should only be done by someone familiar with air brake systems or by a qualified technician to avoid safety issues or air leaks.

Are replacement air tanks and mounting hardware subject to DOT regulations?

Yes, air tanks are a functional part of the truck's air brake system, which falls under FMVSS and DOT safety standards. Any replacement tank should meet or exceed the pressure rating and specifications of the original equipment. Wraps and decorative covers themselves are not typically regulated since they don't affect brake function, but they should never obstruct valves, fittings, or drain cocks needed for proper system operation and inspection.
