Freightliner Columbia 112/120 Front Axle Air Ride

Frequently Asked Questions About Freightliner Columbia 112/120 Front Axle Air Ride Kits

What does a front axle air ride kit actually include?

A front axle air ride kit typically includes the air spring (air bag), mounting brackets, and hardware needed to replace or upgrade the front suspension components on your Freightliner Columbia 112/120. Some kits may also include height control valves or air lines, so it's important to review the specific product listing to confirm exactly what's included before you order.

Will this air ride kit fit my specific Columbia 112 or 120 model year?

Fitment can vary depending on the model year, cab configuration, and original suspension setup on your truck. Always check the listed year range and specifications on each product page, and if you're unsure, have your VIN or current axle/suspension part numbers ready when contacting our parts team so we can confirm compatibility before purchase.

Can I install this kit myself, or do I need a professional?

Many experienced fleet mechanics and owner-operators install these kits themselves, but front axle suspension work involves critical safety components that affect steering and handling. If you don't have experience with air suspension systems or the proper tools to safely lift and support the front axle, we recommend having the installation done by a qualified diesel truck technician.

How long should the air springs and components last before needing replacement?

Lifespan depends heavily on duty cycle, road conditions, and load weights, but air springs are wear items that break down over time due to constant flexing, road debris, and weather exposure. Cracking, bulging, or a noticeable sag in ride height are common signs it's time to replace them, and catching these issues early helps avoid more costly suspension damage down the road.

What's the difference between OEM and aftermarket air ride kits for these trucks?

OEM kits are built to match the exact specifications of the original Freightliner suspension components, while aftermarket kits are manufactured to fit the same application but may vary slightly in materials, warranty terms, or price point. Both options are chosen regularly by fleets and owner-operators, so the right choice often comes down to your budget, warranty preference, and how long you plan to keep the truck in service.
