Freightliner FLC120 Front Axle Air Ride Kits

Frequently Asked Questions About Freightliner FLC120 Front Axle Air Ride Kits

What does a front axle air ride kit actually replace on my FLC120?

These kits are designed to convert or replace the front suspension components on your Freightliner FLC120 with an air ride setup, typically including air springs (air bags), brackets, mounting hardware, and related linkage. They are built to work with the front axle suspension system rather than the cab or seat air ride components, so make sure you are ordering for the correct application before you buy.

Will this kit fit my specific FLC120 model year and configuration?

Front axle air ride kits can vary based on axle type, frame width, and the original suspension setup on your truck, so fitment is not always universal across every FLC120 built over the years. Before ordering, check your truck's axle specs and, if you are unsure, reach out to our parts team with your VIN or axle information so we can confirm the kit matches your rig.

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

Some experienced DIY mechanics with the right tools and a lift can install these kits, but front suspension work involves ride height, alignment, and safety-critical components, so many owners choose to have a qualified truck suspension shop handle the installation. If you are not comfortable with suspension work or do not have access to proper lifting equipment, professional installation is the safer route.

What is included in the kit versus what I might need to buy separately?

Most kits include the core air ride components such as air springs, mounting brackets, and hardware, but items like air lines, height control valves, fittings, or a compressor/air supply upgrade may or may not be included depending on the specific kit. Always check the product listing's included parts list closely, and plan on sourcing any additional air system components if they are not part of the kit.

How do I know if I need to replace worn parts or the entire air ride kit?

If you are dealing with a sagging front end, uneven ride height, air leaks, or a cracked air spring, it is worth inspecting the individual components first since sometimes only the air bag or a bracket needs replacing rather than the full kit. However, if your current setup is outdated, damaged in multiple places, or you are upgrading from a leaf spring front end, a complete kit ensures all the parts are matched and work together properly.
