I considered the Air Lift 1000s until I learned they have to be inflated BEFORE any weight is loaded (all guess work).
I went with the Timber Grove and I'm extremely pleased. The Timber Groves are top quality, easy installation and outstanding support. It's the owner/designer who answers the phone and is most willing to help and suggest with your questions or needs.
I used the single air line as it is considered more stable. For example, in a dual air line system if one side fails it creates an unbalanced & unstable condion. If in a single line system an air line fails you merely lose the effects of the air bags, no off balance or instability.
I have a dual Firestone system on my 2006 Ford F350 and have never had to air up one side differently from the other, have always aired them the same. So, on my Ram, for safety and eae of airing, I went with the recommended one line system.
I connected the Timber Grove system to an Air Lift WirelessOne Compressor System, # 25870.
With this setup I can raise or lower the rear end with a wireless remote controller, anytime, loaded or unloaded.
This system at idle (5psi in bags) raised the rear end 1".
I raised the front end with Hell Bent Steel's 2" top quality spacers, # 125-200-001 .
My Ram has a metal plate on top of the strut, I also included the plate that comes with the HBS kit. Total front rise is 2 1/4"
I am extremely pleased with the quality, usefulness and effectiveness of these modifications.
Timber Grove and Hell bent Steel were very helpful and knowledgeable whenever I called them.
