      Replacement shock on Mach 1

      These are a good all around beginner entry level replacement, as they are Non adjustable. You can buy cheaper shocks but you get what you pay for. For my Mach1 and what I do with the car they are great, ride is drastically improved along with handling. I also replaced the lower and upper control arms.

      Rear shock

      A little to stiff for me. Was looking for a smoother/comfort ride.

      Big difference

      Before I replaced my rear shocks with the Bilstein shocks every time I would hit a bump or a small speed bump the rear end would always bottom out. But with the new shocks that I've ordered replaced my ride is way smoother now.

      Bilstein HD Rehocks

      I have a 1998 GT with HandR Super Sport Springs. I had koni str.t rear shocks and on my car they just were not enough. I wish I would have got these at first! The Bilsteins HD are so much better in everyway you will love these things!

      mach 1 rear shocks

      I wanted the best product available to me in the aftermarket. I am in mgt in a parts supply store in Tucson and am not a stranger to suppliers/quality/price , I am happy with the American muscle support , they considered a request for sale price matching on a order placed near a sale after ordering prior to sale - great job. the shocks ordered were installed , I am satisfied with their performance and will look forward to ordering the front struts to match. I could have purchased Monroe/kyb product through my store - but want the best for my mach , thank you am mus for your customer support , we at merles are doing the same everyday , nice to receive , after giving everyday. thank you guys !!!

      Great Shocks Worth The Money

      I purchased mine on Cyber Monday, so I got a heck of a deal on them, but I'll go back with these at normal cost when these wear out, they are great, and I've tried a couple diff ones. Hands down worth the money, they are stiff but not harsh, it's a subtle stiff, comfy.

      Great replacement shock for big improvements

      My rear shocks and struts were shot on my Mustang, so I bought these to not only fix the issue, but help improve the handling, and boy did it do just that. It rides firm, yet not harsh, and the handling is way better. I can turn into corners significantly faster and it takes the bumps well.

      Cheap and easy

      I bought these along with bilstein quad shocks and removed stock and installed all 4 things in about an hour, immediately there was a ride differnce, felt more stiff, confident on the road. One of my favorite modifications I've purchased from AM. Thanks! And of course the shipping was great along with quality. 2 day shipping.. cant beat it.

    • Unfortunately, this Bilstein HD Series Rear Shock is designed for 94-04 GT, V6, Mach 1 and 94-98 Cobra, it will not fit a 91 LX Mustang.
