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 .
