what brand are the shock absorbers?
gary l on Jan 14, 2016
BEST ANSWER: I don't remember the brand but I'm pretty sure they weren't a major name like Monroe or Gabriel. Having said that, the air bags were a pain to change but the shocks were super easy. I have had zero problems with the performance or reliability of these components since installed. I would trust buying them again.
