Pacbrake's ALPHA HD air springs add the load support the factory rear suspension never had, so the van or chassis stays level, tracks straight and stops wallowing over bumps when it is working.\u003c\/p\u003e\n\u003cp\u003eUp to 5,000 lbs of load leveling capacity covers cargo vans, cutaways, box and service bodies and Class C motorhomes. Everything bolts on behind the rear axle with no vehicle modification.\u003c\/p\u003e\n\u003cp\u003eThis is the PRO S version: the air springs carry an internal flexible polyurethane bumper that stops the bag bottoming out if it loses pressure, and lets you run at 0 psi unloaded for factory ride comfort. Every fastener, fitting, valve and roll plate is stainless, and the air lines are braided stainless. Jounce bumpers do reduce bag travel, so if you need maximum travel for off road use, launching boats or dropping the rear to hitch a trailer, choose the HP10690 kit instead.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e HP10690-J-S\u003c\/p\u003e\n\u003ch6\u003eFeatures\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eUp to 5,000 lbs of load leveling capacity\u003c\/li\u003e\n\u003cli\u003eDouble convoluted air springs\u003c\/li\u003e\n\u003cli\u003eOne piece aluminum end caps, not plastic\u003c\/li\u003e\n\u003cli\u003e20 support wires for maximum strength and durability\u003c\/li\u003e\n\u003cli\u003eInternal polyurethane jounce bumper, so the bags can be run at 0 psi when unloaded\u003c\/li\u003e\n\u003cli\u003eStainless steel mounting hardware, fittings, Schrader valves and roll plates\u003c\/li\u003e\n\u003cli\u003e6 ft braided stainless steel air lines\u003c\/li\u003e\n\u003cli\u003eNo vehicle modification required\u003c\/li\u003e\n\u003cli\u003eLifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2 air springs\u003c\/li\u003e\n\u003cli\u003eCorrosion resistant roll plates\u003c\/li\u003e\n\u003cli\u003ePrecision laser cut powder coated steel brackets\u003c\/li\u003e\n\u003cli\u003eGrade 5 plated hardware\u003c\/li\u003e\n\u003cli\u003eAll accessories required for the perfect bolt on install\u003c\/li\u003e\n\u003cli\u003eComprehensive installation guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eNotes\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eFits E-350 SRW and DRW van, stripped chassis, cutaway and Class C motorhome models\u003c\/li\u003e\n\u003cli\u003eWill not fit 2025-2026 stripped chassis and full custom body models\u003c\/li\u003e\n\u003cli\u003eStainless hardware installs per supplement L6623 alongside the L6653 kit instructions\u003c\/li\u003e\n\u003cli\u003eSome Pacbrake catalogues list this kit as ALPHA XD PRO S.
