Match the fix to the job: Air Lift for truck load support, Monroe Max-Air or Gabriel HiJackers for occasional loads, Arnott for OE air repair or conversion. Set pressures carefully and verify alignment.
Start by naming the problem you want to solve. If your truck or SUV sags with a trailer or cargo, you want load support at the rear. If your sedan feels loose after years on factory air, you want OE-style replacements. If you are done chasing leaks and compressor faults, you want a conversion. Shockwarehouse stocks all three approaches, so you can buy what fits your situation instead of forcing a one-size solution.
If towing or hauling is the main concern, choose Air Lift LoadLifter 5000 for serious tongue weight or bed loads. These bolt-on air springs sit alongside your leafs and give you the pressure range to level the rear and restore steering geometry. For lighter duty trucks, SUVs, and vans that carry weight only now and then, Air Lift RideControl offers the same idea with smaller capacity and a smaller price tag. Both use fill valves so you can tailor pressure for the day’s load.
If you rarely haul but want the rear to sit right on vacation weeks, air-assisted shocks are the most affordable path. Monroe Max-Air brings airline inflation to familiar twin-tube shocks, which lets you top up pressure with luggage on board, then return to your normal setting for school runs. Gabriel HiJackers deliver the same concept with a tough design and a leveling claim up to 1,100 pounds per pair. These shock-based systems help you keep headlights level and reduce that “porpoise” feeling after dips without installing new brackets or heavy hardware.
For vehicles that came with factory air and now show codes, sag at one corner, or run the compressor constantly, Arnott is the fastest way back to normal. Use Arnott air struts or air springs to replace leaking components, and add an Arnott compressor when the pump has aged. You keep automatic leveling and ride modes, the dash quiets down, and the cabin returns to the calm you remember. If you would rather remove the air system entirely, an Arnott coil-spring conversion kit trades variable height for fixed simplicity so you stop spending money on lines, bladders, and pumps.
No matter which lane you choose, finish well so the result lasts. Route airlines away from exhaust and moving parts. Observe each kit’s pressure rules and make changes in small steps. After you alter rear height, aim the headlights and, if the steering wheel sits off center, schedule an alignment. Use a short test loop with one rough section, a long sweeper, and a mile of highway to confirm the stance and the feel. Save the pressures that worked for each trailer or cargo scenario so you can repeat success without guessing.
