I just got some Rancho Quicklifts in today and I figured I might as well replace the rear shocks while I'm at it. I drive highway a good bit during the school year and when I go to work I go over a couple of real rough railroad tracks. Would I be better off with the Bilstein HD series or the Rancho RS9000XL shocks?

 

If you have Ranchos on the front, I would stick with Ranchos on the rear. Bilsteins could have a different setup, making a difference between front and rear very noticeable and make for a lousy or dangerous ride.

 

The RS9000XL are also 9 position adjustable.
