Sterling A-Series Truck Front Axle Air Ride Kits

Frequently Asked Questions About Sterling A-Series Truck Front Axle Air Ride Kits

What does a front axle air ride kit actually do?

A front axle air ride kit replaces or supplements the factory leaf spring or solid mounting setup with an air suspension system. This allows the front end of the truck to ride on air bags instead of steel springs, which typically results in a smoother ride, better handling over rough roads, and reduced vibration transferred to the cab and frame.

Will this kit fit my specific Sterling A-Series model and configuration?

Sterling A-Series trucks were built with different front axle capacities, frame widths, and wheelbase configurations depending on the model year and application. Before ordering, check your truck's axle rating and frame dimensions against the kit specifications listed on the product page, and compare them to what is stamped on your front axle or listed on your build sheet. If you are unsure, contacting our parts team with your VIN or axle tag information is the best way to confirm fitment.

Can I install a front axle air ride kit myself, or should I have a shop do it?

These kits involve modifying or replacing suspension components that support the full weight of the front of the truck, including brackets, air bags, mounting hardware, and sometimes axle spacers. While an experienced diesel technician or fleet mechanic with the right tools and lift equipment can often complete the installation, this is not typically a driveway job. If you do not have experience with heavy-duty suspension work, we recommend having a qualified truck repair shop handle the install to ensure everything is torqued and aligned correctly.

Do these kits affect ride height, alignment, or steering geometry?

Yes, changing from a leaf spring setup to an air ride system can change your ride height and, in some cases, steering geometry if not installed and adjusted properly. After installation, it is important to check and reset ride height to the manufacturer's specification and have an alignment performed. Skipping this step can lead to uneven tire wear or handling issues.

What maintenance does a front axle air ride kit need after installation?

Air ride systems rely on air bags, air lines, fittings, and often a control valve or height control linkage. Over time these components can wear, leak, or loosen, so it is a good idea to periodically inspect air lines for cracking, check fittings for leaks, and confirm the air bags are not rubbing against nearby components. Regular visual inspections during routine maintenance can catch most issues before they lead to a breakdown.
