LoadLifter 5000 Ultimate
Introduction
The purpose of this publication is to assist with the installation, maintenance and
troubleshootingofthe LoadLifter5000Ultimate airspringkit. LoadLifter5000Ultimate utilizes
sturdy, reinforced, commercial grade single- or double-bellows (depending on the kit). The
bellows are manufactured like a tire with layers of rubber and cords that control growth. An
internaljouncebumper insidethespringabsorbs shock andeliminates harshjarring on rough
roads. The internal jounce bumper replaces the factory bumper and allows the air springs to
safely be run at zero air pressure. LoadLifter 5000 Ultimate kits are recommended for most
3/4 and 1 ton pickups and SUVs with leaf springs, and provide up to 5,000 pounds of load-
leveling support with air adjustability from 5-100 PSI. The kits are also used in motorhome
rear kits and some motorhome fronts where leaf springs are used.
