Maxloader overload springs for Isuzu NPR chassis trucks are designed to assist the factory leaf springs when they compress down onto the helper springs, eliminating pre-tensioning and a constantly stiff ride.

The Maxloader Overload Spring Support Systems provides additional spring support to your truck.
The Maxloader was designed to assist the factory leaf springs when they compress down onto the helper springs, eliminating pre-tensioning and a constantly stiff ride.
The Maxloader System is easy to install, safe for all operations, and will never wear out. The Maxloader Overload Springs install between the axle and your factory leaf springs.
Unlike other systems that mount above the leaf spring and always work against the factory springs, the Maxloader Helper Springs only provide additional support when the factory springs are loaded. This allows for a plush, factory ride during daily commutes, while providing increased support and stability when hauling and/or towing heavy loads.
The below the spring mount is designed to only engage when needed and eliminates any pre-tensioning allowing for a factory ride empty or full.
The Maxloader Helper Springs are as long as your factory leaf springs, providing support to the factory leafs at three key points; both spring ends and in the center mounting location. This ensures an evenly distributed load and prevents fatiguing stress that other systems exhibit and eventually cause broken leaf springs. This unique design is also very effective at eliminating swaying and rolling characteristics, especially in corners. Installation is easy and and can be quickly accomplished with only a few bolts; no clamps, drilling, or air system components.
The end result of a Maxloader Overload Spring Support System is a vehicle that rides smoother and more level, with evenly distributed weight resulting in less strain to the drivetrain and suspension components.
All Maxloader Systems are backed by a Lifetime Warranty.
