Air Lift adjustable air helper springs level your load, and give your truck, van, or SUV a safer, more comfortable ride.

Just add air when towing or hauling a heavy load, and reduce air pressure when unloaded, they are fully adjustable for a great ride. Air Lift air springs eliminate sag, sway, and bottoming out. They are made with rugged, durable components for long, reliable service. LoadLifter 5000 kits are Air Lift's heaviest-rated kits for hauling or towing heavy loads. They have up to 5,000 pounds of leveling capacity, right up to the manufacturer's recommended Gross Vehicle Weight Rating, and are air adjustable from 5 to 100 PSI. LoadLifter 5000 kits fit such popular vehicles as ton and one-ton pickup trucks, many Class A, B & C motor homes, and commercial trucks and other severe uses.

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
