Air Suspension & Helper Springs
Air helper springs, full air suspension, on-board compressors, tanks, management and air bags — Ridetech Suspension, Bilstein, Firestone and more, fitting Chevrolet, Mercedes-Benz, Ford and Dodge vehicles. Shipped to every province, priced in CAD.
Air suspension changes what one vehicle can do. Helper springs above the rear axle level a truck under a slide-in camper or a heavy tongue weight, then deflate again when the truck is empty — where a stiffer leaf pack would ride harshly all year for the few weeks it is needed. That adjustability is the entire argument.
Helper springs do not raise your payload rating. They restore ride height and stability at a load the vehicle is already rated to carry; the axle, tires and gross vehicle weight rating still set the ceiling. A full air system replaces the springs outright and needs a compressor, tank and management to match.
Most listings here carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.
Squatting under a load? Our guide to helper springs and air suspension compares the two, and explains what each does not fix.
Common questions
What is an air suspension kit for trucks?
A set of air springs with the brackets and air line to mount them. They carry load on demand, so the truck sits level under weight without riding stiff when empty.
Do air springs replace the factory suspension?
Helper springs work alongside the factory springs and leave them in place. A full air kit replaces the spring itself, which changes ride height and geometry as well as capacity.
Do you need a compressor with air springs?
Not always. A basic kit can be filled with a tire inflator at a fixed pressure. An on-board compressor is what lets you change pressure from the cab as the load changes.
What pressure should air springs run at?
Enough to level the truck under its current load, within the manufacturer's stated minimum and maximum. Running below the minimum lets the bag chafe, which is the usual cause of early failure.
