i went with these only because i wanted the bilsteins, i wanted the HD's but they only are available for stock to 1" lift. not 2.5" like i have so i needed to step up to the 5100's

i put bilsteins on my 95 with 130k on stock shocks, and they were noticable smoother ride. i'm ordering same shocks for my 01 with 70k on it monday.

great to hear. another positive!
