How to Install a Truck Cab Air Spring

Step 1: Lift & Secure the Cab

Use the truck's cab tilt mechanism to fully raise the cab.

THIS IS NON-NEGOTIABLE: Immediately place sturdy support stands or solid wood blocks under the cab's main frame. Never rely solely on the hydraulic lift cylinder. This is your primary safety backup.

Step 2: Replace the Air Spring

Release air pressure: Locate and disconnect the air line from the old air spring. You may hear a hiss as pressure escapes.

Remove the old unit: Unbolt the top and bottom mounting bolts. Some wiggling or gentle prying might be needed to free it.

Install the new one: Position the new air spring. Hand-tighten the new mounting bolts to ensure they thread correctly.

Reconnect: Push the air line onto the new air spring's fitting until it clicks and locks securely.

Step 3: Test for Leaks & Final Check

Carefully remove the support stands and slowly lower the cab.

Start the engine to inflate the air springs. The cab should rise to its normal height.

Leak Test: Mix soap and water and spray it on the air line connection and the air spring itself. Look for bubbles, which indicate a leak that must be fixed.

Go for a short test drive to ensure stability and listen for unusual noises.
