### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Expect to work once installed, great price!
  

*by A***E on Reviewed in the United States on April 16, 2021*

Bought these for my 38 Dodge Truck 1/2 ton per someone's recommendation. Should be much better than the plain, generic ones still selling for my vintage truck. Can't wait to test them out once the restoration is done

    Quality rear truck shock
  

*by A***S on Reviewed in the United States on June 7, 2019*

My older Nissan 4X4 needed new shocks reading reviews the KYB is said to be reliable and high quality with a stock like ride characteristic. After installing them the ride is smooth empty bed or full load. Comfortable ride well made exactly want I wanted.
