Ordered the 0.5" leveling coils for my 21' 3500 dually with the factory air assist and the truck turned out perfectly level clearing 35s with ease. Paired with Fox 2.0 resi shocks front and rear and the new track bar the truck now rides far better then stock. Thanks Zeb for the great info before purchasing.
The 2.5 level I got worked perfectly to clear 35s and rides a lot nicer driving around town. The kit was fairly easy to install and all the instructions where givin in clear detail
The product is great. Works perfect.
Fantastic customer service, amazing ride quality and was extremely happy to fit 37s.
This kit is awesome! On my truck, this kit made my truck sit dead even on all 4 corners and it rides tremendously better than it did stock. The only thing I could see being helpful is adding a template for cutting the fender liners when using the reservoir mounting brackets
