BEFORE BEGINNING YOUR INSTALLATION
Read through the whole instruction guide before getting started with the installation. Professional installation is recommended for this product.
CONTENTS
- 1/2″ NPT Single Port Heavy Duty Air Spring x 4
SAFETY INSTRUCTIONS
- Do not exceed the maximum load recommended by your vehicle manufacturer.
- Once the air spring is installed it is recommended that the vehicle not be lifted by the frame, as over-extension may occur, resulting in damage to the air spring. However, if you need to raise the vehicle by the frame, deflate the air spring completely.
- Employ equipment for eye protection during drilling operations.
- Ensure that your air system has no pressure before you begin.
Do not inflate the air spring when it is unrestricted. The air spring must be restricted by the vehicle’s suspension or similar structure. Do not inflate beyond the pressure recommended in this manual. Improper use or over inflation may cause property damage or severe personal injury.
INSTALLING THE AIRLINE
- A single 1/2″ NPT fitting is required to connect the airline, we recommend to push-to-connect type.
- Apply thread sealant to fitting’s thread and attach it to the air spring.
- Connect the airline coming from the “fill valve” to the air spring.
IMPORTANT: When cutting or trimming the airline, use a hose cutter, a razor blade, or a sharp knife. A clean, square cut will ensure against leaks. DO NOT USE WIRE CUTTERS OR SCISSORS TO CUT THE AIRLINE. These tools may flatten or crimp the air line causing it to leak.
