LoadLifter 5000 Ultimate
Introduction
The purpose of this publication is to assist with the installation, maintenance and
troubleshooting of the LoadLifter 5000 Ultimate air spring kit . LoadLifter 5000 Ultimate 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
internal jounce bumper inside the spring absorbs shock and eliminates harsh jarring 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 .
It is important to read and understand the entire installation guide before beginning installation
or performing any maintenance, service or repair . The information here includes a hardware
list, tool list, step-by-step installation information, maintenance tips, safety information and
a troubleshooting guide .
