I honestly just purchased Fox and Bilstein's. I have the Fox's on mine, and the Bilstein's are going on my brother's suburban.
I got a crazy a$$ deal on the Fox Shox, which is honestly the only way I would have ever ended up with a set. I picked up a set of Fox 2.0's for $150 used but in great shape.
So far, I am super happy with the Fox's. My buddy with some Bilstein's said the Fox's felt smoother than his.
