Helper Springs for a 2002 Chevy Avalanche Z71 with 6 Inch Lift

Question

Question:

Hello, I was wondering if this Firestone #F4108 air spring kit would fit my vehicle. Its stated to fit 2002 Chevy Avalanche but mine is Z71 with 6 inch Fabtech suspension lift in which I replaced the rear springs that came with the Fabtech kit. Would there be a spacer or different air spring I would need to get? Will the F4108 work with this longer spring still?

Since the springs are longer than stock on your 2002 Chevy Avalanche air bags that fit inside the springs, such as # F4108 will not work. There are not spacers available that would work either. But I do have a solution for you.

You could use Timbren springs # TGMRG25C for a 1500 or # TGMRSB4S for a 2500. Then you would need 8 of the 1 inch spacers, # A25723-90AH00, 4 for each side. Timbren does not recommend using any more spacers than that so there will still be a little travel before the helper springs engage. You will also need much longer hardware because of the spacers and it will need to be obtained locally.

The problem with this is that lateral stability could be a problem because of the amount of spacers needed.

Another option would be to use SumoSprings # CSS-1125R. The space between the coils would have to be 1-1/8 inches for these to fit.
