Review on Enhance Suspension Performance with Air Lift 52440 Air Lift Spacers by Dave Willis
So far so good for shocks, struts and suspension
They worked great on my 2015 Sierra 2500 Denali HD with a Fabtech 6" lift. My 6" factory lift that was installed over an ALC lift has 4" lift blocks in the rear and I had to cut the stops that were part of the block to fit the unit and the 57538 Load Lifter 7500 XL pneumatic lift to mount.
Pros
- Lots of positive vibes
Cons
- Protection
