Re: Still Concern on Quadra-Lift in 2014?
The only real common "issue" is that not being of metal, you do have wear and tear. Ain't nothing you can do about that. On the other hand, steel springs do wear out eventually too.
My '11 with QL has had no QL issues at all, it works awesome and I wouldn't buy one of these without it unless I planned to do a big lift kit or something.
