Rated 5 out of 5 by Easy Installation. Replaced worn shocks on '05 Excursion. These were an easy install with a few wrenches and sockets/ratchets. Note: have a breaker bar or extension ready for existing bolts and nuts. September 4, 2016

Rated 4 out of 5 by Front shocks for my 2500 MB sprinter Good price for the product, quality is not bad for half the price of an OEM one. Works great just had them put on my 2011 sprinter 2500. August 8, 2016

Rated 5 out of 5 by Easy Instalation & Major Improvement at a great price Gas powered Monroe shocks have made a huge improvement in my vehicle overall handling. April 30, 2015
Rated 5 out of 5 by Excellent Shocks! Great shocks at a great price! Was able to install these shocks and they just continue to get better on my vehicle. Huge improvement over my stock KYB shocks. April 30, 2015
Rated 4 out of 5 by product worked everything was in the package that was needed. December 27, 2014
Rated 5 out of 5 by Ood product So far i have only the rear installed. Smoother ride ever. My car is a heavy 99 expedition so the shock does hold wonderfully. December 19, 2014
Rated 5 out of 5 by Fixed front end vibration On a 2005 Excursion Diesel, these shocks fixed my front end vibration. I thought I had ball joints going out but it was just shocks. So far they are a nice ride and the truck drives so much better. November 7, 2014
Rated 5 out of 5 by Great Shock, Really improved the ride I purchased a pair of Monroe Gas-magnum shock absorbers for my 1994 F-150 and got a great shock at a great price. The truck rides and handles so much better. October 18, 2014
Rated 3 out of 5 by OEM level ride at a decent price Front better than rear on ride. Rear better than front on installation. These Monroe Gas Magnum shocks give approximately the original OEM shock level of ride at a decent price. I'm sure better riding shocks exist, but they seem to cost 4 times as much. If you have an SUV and do towing, I would recommend load leveling shocks instead of these Gas Magnums. If you just drive, even offroad, but no towing, these seem OK. August 15, 2014
Rated 5 out of 5 by Monroe shocks have always been tops in my book I was an ASE certified mechanic and have installed shocks of every brand and type in my time. Monroe Shocks have always been the best and have stood the trials of time. I remember installing the Monroe Magnum on many trucks and HD vehicles so it was a natural choice for my Ford Expedition. I feel very confident with this brand and expect many smooth miles in the future. January 1, 2014
Rated 5 out of 5 by Excellent Gas-Magnum Shock Abosorbers for 2012 Ford E-150 Passenger Van These shocks are amazing and made a huge difference to the quality ride of the van. I was hesitant to rather keep the existing manufacture shocks that came with the van or upgrade them to the monroe gas-magnum for the longest time, but since pep boys had the 20% off deal I decided to switch them. Boy, take my words from it. The ride feels like from a 1970's Hyundai to a brand new 2014 Bentley. That 's how big of the high quality these shocks make to the ride. Get them!!!!!! September 30, 2013
Rated 5 out of 5 by Shockingly good I bought a 2002 Dodge 1500 with 74000 miles. I found that it still had the OEM shocks on it, whick explained the pogo stick like ride. I put a set of these Gas Magnums on the rear and it really settled things down. I plan to do a set up front too and that should improve the steering stability. These are great shocks! August 18, 2013
