I contacted the merchant that sold me the Firestone Coil-Rites. The service rep asked that I give him a couple days to get Firestone to respond to my complaint. They did not respond.

Here is the latest email from the merchant:

Good morning, I know they are busy but they need to be able to make a phone call to one of there customers. I tell you what, if they don't contact you by the end of the shipping day today I will just send you out a replacement kit from our warehouse and deal with them on the warranty end of things. Its 8:41 right now local time, if you do not here from them by 3:00 my time which is Mountain Standard Time than email me back and I will ship them from here. Sound good?

THE MERCHANT IS: SUSPENSION CONNECTION (dot) com and I thought I would give them a plug for their cooperation.

THEY ALSO SELL THE AIRLIFT BRAND. (hint-hint)

 

Air Lift 1000's ordered! I have been waiting for a long time to place this order. I was looking at the Firestone bags but there seem to be complaints about them and I have never heard anything bad about the Airlift bags.

 

Wish someone made a set for us lowered guys. Most are for stock springs in the rear.

 

I know it's difficult to get accurate and precise specs but it may be possible to find a set for a different vehicle which requires shorter air bags that would fit.

 

i have the firestones, easy to install and only issue i had was that i cut the hose a tad off going into the bag so it leaked but that was fixed after i thought the bag was busted and firestone sent me another bag free of charge(i now have a spare)

i like that the hoses are not connected and i fill each bag separately

this is with our competition bbq trailer which is 5000 or so pounds and my truck is leveled and bags at 30psi

 

SUSPENSION CONNECTION (dot) com sent me a set of Airlift1000 to replace my Firestones.

 

That is where I ordered my Airlift bags from. I also ordered a .75" spacer from top gun today to slide in there when I have the springs out.

 

I went ahead and ordered the air lift kit and an on-board compressor.

 

Got 10,300 miles on the truck and now the 3rd set of airlift failed today at 10,300 miles, first 2 sets failed on drivers side, 1st was on top from bag being pinched between fill block and a coil ring at 7200 miles, 2nd set failed on drivers side on bottom of bag at 7200 miles, 3rd set Airlift changed to the longer version bag at 11.5" with 1/2" nylon filler block, it fits inside the coil saddle rubber but that set failed today on the right side at bottom of bag. lots of pics on last 2 sets during install and after fail.
Factory is hopefully sending 4th set tomorrw, but I am really getting tired of changing them but have it down to a science now, i pull the coils to do it, simpler and less likely to damage the bag. Kit 60818 on all 3 but the first 2 had the short bags at 8.5" with the 3" black filler blocks, last set was longer bags at 11.5" with 1/2" nlon filler block that fir nicely inside the saddle boot.
Hope this helps, I am not giving up on Airlift but hope they help me get it fixed, or find a set of firmer coils and voila no more air issues
