Review: Well worth the money. Fantastic ride quality. - These shocks are awesome. My truck rides some much better now. I had to replace the original shocks on my 2003 GMC Sierra 2500hd. The old ones were completely worn out. These were a little difficult to install alone. As it takes both hands just to compress these while laying under a truck.

You can’t go wrong with Bilstein shocks. Would recommend these over the lower quality Bilstein series.
