Recommended PSI Pressure for Installing AirLift 1000 Air Helper Springs in 2001 Chevrolet Tahoe

Updated 07/01/2015 | Published 06/30/2015

Question:

I have a 2001 Tahoe LS 4x4. Part # AL60769. The instructions say to add 35psi before adding load. I put 30psi in my bags attached my trailer then rechecked the pressure. 33-35psi So if I follow the instructions and put 35psi in the bags before loading I will exceed the 35psi max pressure of 35psi. Will the bags fail? Should I not put 35psi in the bags? My thought is, No. I feel Airlift is giving bad instructions and false information.

You are correct that the instructions for AirLift 1000 Air Helper Springs # AL60769 indicate to inflate the bags to 35-psi to test for leaks. You are also correct that this is the rated maximum pressure for your specific application in a 2001 Chevrolet Tahoe.

The bags themselves can handle a much higher pressure without failure. I confirmed this with my technical contact at AirLift. The reason you're advised to test at the maximum for your vehicle is to best confirm there are no leaks in the system. A lower pressure might not reveal a leak and you'd then find out the hard way after completing your install.

You will not damage your bags by following the inflation instructions.
