Are the front upper and lower, and rear control arms bolt on for our birds. If not then what is needed and what are the benifits? I need front suspension and my bird in a bad way and was looking to upgrade in the process. Thanks for all of the help guys, JOE:)

Only the rear control arms are aluminum, a little lighter than the cast ones. You'll need spring perches to make them work with springs instead of airbags. The front stuff bolts on, but there are no benefits in using the Mark ones.

Yep, you'll need a set of these made up.

If you go with the Mark aluminum rear control arms, be sure and keep all the hardware when removing them. Some of the bolts are longer than the SC rear control arm bolts.

The rear upper arms I have seen from a Mark have holes cut in them (for making them lighter, I guess). I would go with the rear SC upper control arms.
