Load-Leveling System

Developed for vehicles equipped with solid-axle coil spring suspension, the Eibach Load-Leveling-System uses a combination of readily available Eibach Race Springs, adjustable threaded spring seat and bump stops to allow fine tuning of load capacity and ride height. Engineered and tested for each application, the Load-Leveling-System is available in three different load ranges to achieve up to 2.5" of lift for maximum travel and tire clearance off-road.

The Eibach Load-Leveling-System is designed to eliminate the need for air bags, spring spacers, or excessive spring rate to maintain ride height while carrying heavy loads.

Each load range had been tested to deliver up to 2.5” of rear lift while still working within range of the Eibach Pro-Truck-Shocks.

This system allows you to run the appropriate spring rate for your vehicle while maintaining a lift whether the vehicle is loaded or unloaded. This translates to improved ride quality and compliance, on and off-road while maintaining necessary tire and ground clearances.

In addition, readily available Eibach Race Springs make this system adaptable as you continue to add modifications or weight to the vehicle.

The Eibach Load-Leveling-System is optimal for vehicles which are frequently loaded and unloaded for towing, camping trips, or overland expeditions. Armor, roof-top tents, storage shelving, full size spares and tire carriers increase weight ultimately effecting static ride height of your vehicle. The addition of the height adjustable perch allows fine tuning of rear ride heights, keeping your chassis clear from the trail, and tires clear from fenders.
