I would recommend these to anyone
Big improvement from original shocks on my 04 Dodge Ram 1500 with 130,000 miles. I tow trailer with lawn eguipment and also loads of mulch, dirt, gravel, and atv's. These shocks make a difference without having to change or add to your suspension. Took the bounce out of the rear of my truck and made a very smooth ride. These shocks really show how solid my truck should have felt all along. I drive up and down a gravel hill and over potholes and bumps all the time and really noticed a big difference right away. I couldn't believe how worn out my original shocks were until I changed them.

Got squeaky in a short time
I ran these shocks on a 06 Dodge Ram 4x4, replacing OEM shocks. Initially very good performance. They make a difference when under load. However, like a review I read on here. One of my shocks, got squeaky. The rubber bushing on the top of the shock got pushed down and out the way, causing the spring to make contact with the housing. I only carried a ton of wood pellets. I never off-roaded the truck. The shocks were on the truck for about 4 months. I exchanged the shocks for Sensa-trac shocks, they were worse and leaked in under a year. I settled on KYB Monomax and so far so good.

Much needed boost for trailering
These shocks are a much needed boost when towing heavy loads, or just hauling a tongue heavy trailer. The Dodge 1/2 tons have pretty weak leaf springs, and this just gives a little extra UMPH to the suspension. However as someone else has posted, be prepared to work to get these puppies in there.
Bottom Line Yes, I would recommend to a friend
I would buy these again.
Verified Buyer -
Great shocks for price, improved ride, quick install, be ready to have a jack to compress the shock for install cause they are strong. THERE ARE 2 SHOCKS, IT IS A PAIR.
Much better
Verified Buyer -
The springs are kinda squeeky in back. I hope this wears off over time...very annoying. High quality product, much beefier than stock.
Bottom Line Yes, I would recommend to a friend
