i have a 2001 f150 with a fabtech lift. i just replaced the fabtech shocks with some new bilsteins 5100's. The new bilsteins are riding very rough. cornering is awesome but speed bumps make my cd player skip and everything its harsh. I thought these shocks were suppose to be awesome. which is why im wondering if i got the right shocks. the part numbers are be5 6138 t5 for the front and be5 6093 h5 for the rear. i got two retailers saying these are right. Are they?
