2008 ml 350 4matic struts replacement

It definitely makes all the difference in the quieter riding and not to mention every bumb is absorbed with the new Bilstein replacements..They are as I thought they would be, excellent..after all they are Mercedes benz's brand for struts.good as new...The next thing I will be replacing are the bushings on the control arms,to solidify my cars longevity,wanted to sell the car before the replacement but now,more than likely I'm good to enjoy for sure and save for another 2 years and several years for the owner after that.thanksshock plus...and their delivery was prompt,was a bit concerned when the 3 arrived,but looking on the tracking of the shipping,it quickly let me know that there other was on its way...was a perfect fit...thank God for these guys..

Perfect fit

Bad

The wrong parts were sent, and when I returned the shocks, I was not told they were out of stock of what I needed. Then, you did not refund the total purchase price.

Received on time

No issues with fit, matched up with the original on my 2017 Buick with 86k, however I was expecting a smoother result but the ride seems the same, don’t know if the need a break in time or not
