LoadLifter 5000

Introduction

The purpose of this publication is to assist with the installation, maintenance and 

troubleshooting of the LoadLifter 5000 System. LoadLifter 5000 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. LoadLifter 

5000 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 motor home rear kits and some motor home 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, step-by-step installation information, maintenance tips, safety information 

and a troubleshooting guide.
