Designed for demanding towing and hauling applications, the system provides up to 7,500 lbs. of load-leveling capacity to help reduce rear-end squat, trailer sway, bottoming out, and harsh ride characteristics under heavy loads.\u003c\/p\u003e\n\n\u003cp\u003eThe LoadLifter 7500XL uses large 7-inch double-bellow air springs that provide increased air volume, allowing the system to support heavy loads at lower air pressures. This helps provide a balance between load-leveling capability and ride comfort while maintaining better vehicle stability when towing or hauling.\u003c\/p\u003e\n\n\u003cp\u003eEach air spring incorporates an internal jounce bumper that absorbs shock and provides additional support during severe suspension compression. The internal bumper also allows the air springs to be safely operated at zero PSI when unloaded and replaces the factory jounce bumper for a maintenance-free, three-stage ride system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUp to 7,500 lbs. of load-leveling capacity\u003c\/li\u003e\n  \u003cli\u003eLarge 7-inch double-bellow air springs\u003c\/li\u003e\n  \u003cli\u003eIncreased air volume provides load support at lower pressures\u003c\/li\u003e\n  \u003cli\u003eHelps reduce rear-end squat when towing or hauling\u003c\/li\u003e\n  \u003cli\u003eHelps reduce trailer sway and improve vehicle stability\u003c\/li\u003e\n  \u003cli\u003eReduces harsh jarring and bottoming out on rough roads\u003c\/li\u003e\n  \u003cli\u003eInternal jounce bumpers absorb suspension impacts\u003c\/li\u003e\n  \u003cli\u003eCan be safely operated at zero PSI when unloaded\u003c\/li\u003e\n  \u003cli\u003eReplaces the factory jounce bumpers\u003c\/li\u003e\n  \u003cli\u003eProvides three-stage ride comfort\u003c\/li\u003e\n  \u003cli\u003eMaintenance-free design\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eKit Includes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e(2) Air springs\u003c\/li\u003e\n  \u003cli\u003eVehicle-specific mounting brackets\u003c\/li\u003e\n  \u003cli\u003eRequired installation hardware\u003c\/li\u003e\n  \u003cli\u003eFully illustrated installation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2001–2010 Chevrolet Silverado 2500HD\/3500HD 2WD\/4WD\u003c\/li\u003e\n  \u003cli\u003e2001–2010 GMC Sierra 2500HD\/3500HD 2WD\/4WD\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The 7,500-lb. rating represents the air spring system's maximum load-leveling capacity and does not increase the vehicle's factory GVWR or payload rating.\u003c\/p\u003e","brand":"Air Lift Company","offers":[{"title":"Default Title","offer_id":53903084814619,"sku":"57575","price":713.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/5757\/3147\/files\/Screenshot2026-09-07at11.28.10AM.png?v=1789055768","url":"https:\/\/wwmperformance.com\/products\/air-lift-loadlifter-7500xl-helper-spring-kit-57575-2001-2010-6-6l-duramax","provider":"WWM Performance","version":"1.0","type":"link"}
