Restore consistent ride height with the ContiTech Air Suspension Spring, replacing a bellows that's cracked, chafed through, or no longer holding air overnight. The ContiTech AS9974 uses fabric-reinforced rubber construction that flexes through the full suspension travel without the reinforcement separating from the rubber layer. That layered construction resists the ozone and road-debris abrasion that eventually cracks a bellows surface exposed to constant flexing. Restoring proper air spring function keeps ride height and axle geometry consistent instead of the sag a leaking bellows causes.
