Signs your suspension needs attention
Worn suspension parts wear out tires, brakes and drivers. Catch them early.
Leaning or low ride height
A sagging corner or frame height off spec often means a leaking air spring or a faulty leveling valve.
Air leaks
Hissing at air springs, fittings or the height control valve, or the system slow to fill.
Bouncing and rough ride
Excessive bounce after bumps points to worn or leaking shock absorbers.
Uneven tire wear
Cupping or scalloping on tires is a classic sign of worn shocks or bushings.
Clunks over bumps
Knocking from worn torque rod ends, beam bushings or loose U-bolts.
Axle walk or pulling
Worn torque rods or bushings let the axle shift and the truck pull.
Safety first: have suspension work done by a qualified technician, and follow the vehicle and suspension manufacturer's specifications and torque values.
Frequently asked questions
What suspension parts do you supply for trucks and trailers?
We supply air springs (air bags), shock absorbers, height control (leveling) valves, torque rods and bushings for North American and European trucks and trailers.
How do I know if an air spring is failing?
Common signs are a leaning or low corner, air leaks or hissing at the bag or fittings, a system that is slow to fill, and a rough ride. Have the suspension inspected by a qualified technician.
How do I find the right air spring?
Use the part number printed on the old bag, such as a Firestone W01-358-9082 or Goodyear 1R12-092, or send the vehicle make, model, year and axle. We cross-reference Firestone, Goodyear, Contitech and Hendrickson numbers and confirm fit.
Should air springs be replaced in pairs?
It is often recommended to replace both bags on the same axle so ride height and load sharing stay even. Ask your technician, and we can quote a pair.
