The best brand of shocks for vehicles and is what I installed on my truck are the Monroe brand of shocks.
Monroe shocks are very comfortable riding shocks for trucks and other vehicles and they are a good quality of shocks as well.
I installed the Monroe MA822 Max-Air Adjust Shock Absorber and I've read great reviews on the Bilstein (24-186742) 5100 Series shock absorber.
Getting quality shock absorbers for your vehicle will be well worth the cost as it will give you a nice comfortable ride.
I always pay for quality shocks and after about 10 years I replace them as the shocks seem to get worn out and then the ride gets less comfortable.
The bushings seem to wear out overtime and I replace the shocks and the ride quality improves.
