Review on 1 Pack MOOG 81649 Coil Spring Set - Enhance vehicle performance and reliability by Jonathan Ulsth

I bought these to replace my old (125,000 miles) factory rear springs. I also planned on using a Firestone Coil-Rite auxiliary air spring to keep the truck level when towing. Well, MOOG springs have thicker springs and more coils than standard springs (I believe they match OEM spring specs) which makes the inner diameter too narrow for air assist springs. I had to choose between installing MOOG or Air Helper springs and chose the latter. I wish I could do both.
