+1 2008 jeep GC.
to the above poster--- match them-- the sensatraks valve differently than reflexes. I had sensatraks on my last jeep and was happy with them. they are a little more civilized on the hwy-- they give more at flat ride height, which the reflexes don't do. mine is lifted, so the sensatrak wouldn't work in this application. don't mix sensa's and reflexes.
both are good.
btw - reflexes feel as stiff to me as KYB GR2s. However, the GR2s handled things like speed bumps and potholes better. Like.... Reflex feels like a good truck shock that handles multiple weights but focuses on control more and vehicle dynamics less. GR2s would be better if the vehicle was not subject to hauling different weights around-- was more finely tuned.
