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, depending on the kit, convolute
bellows . 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 ¾ and 1 ton pickups and SUVs with leaf springs and provide
up to 5,000 lbs . 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 .
