5100 Shocks
Very impressed at how much better the ride quality felt after initial install. The reason I’m only giving three stars is because a week after install, they started feeling just as bad as the old worn out stock shocks. Unfortunately for me I am outside of the return window, so not much I can do. Regardless of my issues, I would still recommend these shocks.
5100 shocks
Very impressed with the ride quality and construction for the price, got rid of the floating/bouncing feeling of the tired factory Chevy shocks.

Questions and Answers

I have a stock 06 duramax. If I install the Bilstein 5100 shocks front and back can I go to bigger tires. $$
View Staff Answer 
Aftermarket shock absorbers will not raise the vehicle. In order to run larger tires you will have to either level or lift the truck.

I have an 02 duramax. It has an add a leaf and measures 24 1/2 extended. Are these the right ones?

For an 01-10 GM 2500/3500HD 4WD truck with a 4" lift, you would require this Bilstein Shock found HERE.
