Fitted with B8 5100 front and rear shocks. Full of rubbish in my opinion! The boost pressure is so high that I turn the steering wheel to the right when I let go of it. Also, after installing the complete Bilstein kit, my truck started to rock and roll severely. I am afraid to drive a truck on wet roads or at high speed for fear of hitting a bump and going off the road. Believe me. Stay away from this brand and try something different. I wish I had!
