The bellows is what carries the load and maintains ride height in the air suspension, and when it cracks, chafes or starts leaking you get a sagging chassis, air leaks that run the compressor ragged, a punishing ride, and shock absorbers that fail 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.\u003c\/p\u003e\n\n\u003ch2\u003eStraight Swap on Kenworth and Peterbilt: The Econoride Air Spring Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThis is the \u003cstrong\u003eEconoride\u003c\/strong\u003e replacement for the \u003cstrong\u003eFirestone 5479\u003c\/strong\u003e rolling lobe bag used on \u003cstrong\u003eKenworth and Peterbilt\u003c\/strong\u003e air suspensions, and it also carries the Paccar number \u003cstrong\u003eC81-1017\u003c\/strong\u003e. Rolling lobe construction lets the bellows roll along the piston instead of stretching, which is what keeps the spring rate soft and consistent whether you are loaded heavy or running empty.\u003c\/p\u003e\n\n\u003cp\u003eThe rubber compound is built to take road salt, spilled lubricants, freezing temperatures and highway debris without weeping down overnight. At 16.5 lbs this is a substantial bag, so support the axle before you unbolt the old one. One fitment note before you order: this spring is similar to \u003cstrong\u003e8864\u003c\/strong\u003e, but it needs an \u003cstrong\u003eABB1K2\u003c\/strong\u003e kit in addition — check what is on the truck first so every part is on the bench when the wrenches come out.\u003c\/p\u003e\n\n\u003cp\u003eAt FleetPro Parts \u0026amp; Tires, we know a suspension job is only right when the part is right. This spring is a direct replacement for highly searched industry numbers including Firestone \u003cstrong\u003e5479\u003c\/strong\u003e, W01-687-5479 and W016875479, plus Paccar \u003cstrong\u003eC81-1017\u003c\/strong\u003e and C811017. Always inspect the mounts and shock absorbers when you replace an air spring — a dead shock will destroy a brand new bag.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eVehicle Fitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis heavy-duty aftermarket air spring is intended for the following commercial applications:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMake\/Model:\u003c\/strong\u003e Kenworth, Peterbilt\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e Air suspension — carries the load and maintains ride height\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Group:\u003c\/strong\u003e Air Suspension \/ Air Springs\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Similar to 8864, but requires an ABB1K2 kit in addition\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDirect Replacement \u0026amp; Cross-Reference Numbers:\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eThis Econoride air spring serves as a direct replacement for the following part numbers:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFirestone Interchange:\u003c\/strong\u003e 5479, W01-687-5479, W016875479\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePaccar Interchange:\u003c\/strong\u003e C81-1017, C811017\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomann Distributor #:\u003c\/strong\u003e 566.ER5479\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Rolling Lobe Air Spring\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Kenworth, Peterbilt\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Similar to 8864, requires an ABB1K2 kit in addition\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 16.5 lbs\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePackage Dims:\u003c\/strong\u003e 10.75 x 10.75 x 15 in\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProduct Level:\u003c\/strong\u003e Fleet Value Aftermarket\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Econoride (Distributed by FleetPro Parts \u0026amp; Tires)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Econoride","offers":[{"title":"Default Title","offer_id":43024037544007,"sku":"566.ER5479","price":92.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8035\/2583\/files\/image_1920_9c0f9986-f144-4ea4-8b89-edcef79c02db.jpg?v=1785427995","url":"https:\/\/fleetpropt.com\/products\/econoride-rolling-lobe-air-spring-kenworth-peterbilt-firestone-5479-w01-687-5479-paccar-c81-1017-566-er5479","provider":"FLEETPRO PARTS \u0026 TIRES ","version":"1.0","type":"link"}
