Introduction; Important Safety Notice; Notation Explanation - Air Lift LoadLIFTER 5000 ULTIMATE Installation Manual

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.

IMPORTANT SAFETY NOTICE

The installation of this kit does not alter the Gross Vehicle Weight Rating (GVWR) or payload
of the vehicle. Check your vehicle's owner's manual and do not exceed the maximum load
listed for your vehicle.
Gross Vehicle Weight Rating: The maximum allowable weight of the fully loaded vehicle
(including passengers and cargo). This number — along with other weight limits, as well
as tire, rim size and inflation pressure data — is shown on the vehicle's Safety
Compliance Certification Label.
Payload: The combined, maximum allowable weight of cargo and passengers that the
vehicle is designed to carry. Payload is GVWR minus the Base Curb Weight.
