I do have the co's, but not the upper a-arms. I only run about 1.5" of lift and no aftermarket bumper. So far I've been very pleased since I got a great deal on them (only $500 brand new) If you're going to spend the approx. $750 or more buy the Hoe's, just my 2cents. I live in AG, so if you want a ride or want to check them out pm me.
