Econoride Rolling Lobe Air Spring - Metric Inlet W-Spyder Top Plate - Freightliner Cascadia M2 SD - 566ER79562 566.ER79562

Put your Freightliner back on its ride height with this Econoride Rolling Lobe Air Spring distributed by FleetPro Parts & Tires. It carries the load and maintains ride height in the AirLiner-style air suspension used under the Cascadia P3, Cascadia P4, 114SD, 122SD, M2 106 and M2 112. A cracked, chafed or leaking air bag drops the chassis, leaks air all shift long, beats up the driver and the freight, and finishes off the shock absorbers right behind it. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Metric Inlet, W-Spyder Top Plate: The Econoride Air Spring Advantage

Two details decide whether an air bag bolts up on these chassis, and this one gets both right. First, it uses the metric air inlet and studs — order the imperial-inlet version by mistake and the air line will not thread, the studs will not line up, and the truck sits on the lift while you wait on the right part. Second, it carries the W-Spyder web design top plate used on the AirLiner suspension, so the load spreads across the plate the way the factory bag did.

Dimensionally it runs a 12.5in design height and 12.6in maximum diameter at 12 lbs, matching the geometry the ride-height valve is calibrated around. The rolling lobe bellows rolls along the piston instead of stretching, which keeps the spring rate soft and consistent whether you are loaded to the ceiling or deadheading home, and the rubber compound resists road salt, spilled lubricants, freezing temperatures and highway debris.

At FleetPro Parts & Tires, we know a suspension job is only right when the part is right. This spring is a direct replacement for the highly searched Econoride number 566ER79562, and it is stocked, boxed and ready to ship the day you order it. Always inspect the mounts and shock absorbers when you replace an air spring — a dead shock will destroy a brand new bag in a hurry.
