Leveling Solution 74320 Air Spring Kit for Heavy Haul

When you regularly tow or haul heavy loads, your truck’s rear suspension bears the brunt. Sagging rear, reduced stability, and sway in windy conditions are common headaches. Leveling Solution’s 74320 air bag kit provides a bolt‑on leveling solution that adds robust load support for pickups and heavy‑haul tasks. It helps you maintain a level ride and confident control, even with a heavy payload.

Air suspension is increasingly popular for improving load handling. Before you buy, it helps to understand how these systems work, what they include, and how they stack up against traditional springs.

Why air suspension can be a smart upgrade for heavy hauling

Air suspension uses air-filled bags to provide dynamic load support. Unlike fixed coil or leaf springs, air bags can be inflated or deflated to match weight and road conditions. This lets you raise or level ride height and adjust firmness for different loads. For frequent haulers, that translates to less rear sag, more stability, and smoother handling at highway speeds.

Air suspension vs spring suspension

Conventional springs—coil or leaf—are simple and reliable but have fixed stiffness. They don’t self‑adjust to load, so heavy payloads compress the springs and cause rear sag. Air suspension, with adjustable air pressure, tailors support to the load and conditions. The result is a more level ride, better weight distribution, and improved control when towing or hauling. It isn’t without tradeoffs—more components mean more maintenance and potential leaks, and price can be higher than basic springs.

What makes Leveling Solution 74320 different

This kit includes a pair of double‑convoluted air bags with a robust 5,000‑lb level load capacity. It’s a true bolt‑on solution that uses included mounting brackets, air lines, and all mounting hardware. There’s no drilling required, and the system uses push‑to‑connect air fittings for quick, secure connections. The components are moisture‑ and dust‑resistant for durability in tough environments. With adjustable air pressure, you tailor support to match payload weight and road conditions, delivering a smoother, more controlled ride. The kit is designed and assembled in the USA and backed by a 5‑year warranty for peace of mind.
