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 (2,268kg) 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.
