Introduction

The purpose of this publication is to assist with the installation, maintenance and 
troubleshooting of the standard LoadLifter 5000, LoadLifter 5000 Ultimate or LoadLifter 
5000 Ultimate Plus air spring kits. All LoadLifter 5000 Series kits utilize sturdy, 
reinforced, commercial-grade single or double, depending on the kit, convolute bellows. 
LoadLifter 5000 Ultimate kits add an internal jounce bumper and black powder-coated 
roll plates. LoadLifter 5000 Ultimate Plus kits also have an internal jounce bumper, but 
add stainless steel roll plates, air lines and air spring mounting hardware. 
The air springs are manufactured like a tire with layers of rubber and cords that control 
growth. LoadLifter 5000 series 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. 
It is important to read and understand the entire installation guide before beginning 
installation or performing any maintenance, service or repair. 
Air Lift Company reserves the right to make changes and improvements to its products 
and publications at any time. For the latest version of this manual, contact Air Lift
