Carrying heavy cargo, slide-in campers, or heavy tongue-weight trailers strains stock rear leaf springs, leading to light front-end steering control and poor braking stability.\u003c\/p\u003e\n\u003cp\u003eEngineered with heavy-duty double-bellows air springs with composite end caps, this air bag kit provides up to 5,000 lbs of load-leveling capacity. According to SEMA chassis engineering standards, air helper springs level the vehicle profile to keep headlights aimed properly and maintain front tire contact patch under maximum payload. Built to handle sub-zero winter temperatures, road salt exposure, and off-road trail chatter, Pacbrake Alpha HD springs allow independent pneumatic inflation to level off-center loads with confidence.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLoad Leveling Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 5,000 lbs (2,268 kg) Dual Leveling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAir Spring Style\u003c\/td\u003e\n\u003ctd\u003eDouble-Bellow Reinforced Rubber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnd Cap Construction\u003c\/td\u003e\n\u003ctd\u003eUltra-Durable Composite End Caps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBracket Coating\u003c\/td\u003e\n\u003ctd\u003eCorrosion-Resistant Black Powder-Coated Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Pressure Range\u003c\/td\u003e\n\u003ctd\u003e5 PSI Minimum to 100 PSI Maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFifth-Wheel Compatibility\u003c\/td\u003e\n\u003ctd\u003eFits Vehicles Equipped with 5th Wheel Frame Brackets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eMade in Canada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd\u003eHP10340\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChevrolet Silverado 1500:\u003c\/strong\u003e 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMC Sierra 1500:\u003c\/strong\u003e 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBed Lengths:\u003c\/strong\u003e Fits short, standard, and long box configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLifted Trim Note:\u003c\/strong\u003e Factory lifted models (such as Trail Boss and AT4) require a 2\" air spring spacer block kit for proper geometry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment Exclusions:\u003c\/strong\u003e NOT compatible with models equipped with Adaptive Ride Control (ARC) or MagneRide electronic shock absorbers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBolt-on mounting using vehicle-specific hardware; no frame drilling required.\u003c\/li\u003e\n\u003cli\u003eFully compatible with under-bed and in-bed 5th wheel hitch bracket kits attached along frame rails.\u003c\/li\u003e\n\u003cli\u003eIncludes air lines, manual inflation valves, brackets, and required mounting hardware.\u003c\/li\u003e\n\u003cli\u003eKeep a minimum operating pressure of 5 PSI in the air springs at all times to avoid pinch damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the difference between this HP10340 kit and the HP10340-J Pro kit?\u003c\/h3\u003e\n\u003cp\u003eThe standard Alpha HD HP10340 kit utilizes high-strength reinforced composite end caps on the air bags, whereas the Pro version (HP10340-J) features anodized aluminum end caps.
