I'm quite partial to BDS. Got the 4 incher on my Sub to replace the 2 inch Rough Country lift. The name is quite accurate! Rough Country bounced the vehicle around sooo much. Put on the BDS with their shocks and it really made a night and day difference. The ride is still firm yet comfortable, hard to describe. The vehicle also became a lot more controllable. The BDS kit and shocks do not transmit every imperfection in the roadway to the cab like the RC kit did. It really seems to take on the bumps at a higher rate speed and still remain in control.
I could really tell the difference because I had the RC kit on for 10 years so I "knew" the ride before installing the BDS about 3 years ago.
BTW, I've got the BDS new 4" springs in the front, 4" blocks (with my 3/4 ton factory springs) in the rear with their add-a-leaf just to bring up the rear a little more.
Their quality is top notch along with customer service. Although the white paint on the shocks started flaking and rusting pre-maturely. Still function but ain't pretty to look it. Good luck. Check out thier website.
