The new upper a-arms (pics soon) now also feature ball joint moved rearward for caster and the new a-arm design updated for maximum suspension travel. Our new adjustable upper a-arms offer the most travel of any a-arm design on the market.
Lower a-arms now offer 1 degree of caster, uppers 1-3 degrees for a total of 2-4 degrees of positive caster. When used together the spindle pin does not move. Pictures of uppers coming soon.
Ryan and Ramey - I have a question on these.
I see you offer these with Roto-Joints as well. I have the Roto-Joint/Poly combo on my rear adjustable LCAs and Panhard Bar from you guys and they are quiet and work very well on the street. Would it be worth it to upgrade to the dual roto-joints for the boxed lower A-Arm for a street car? Or would the dual rod-ends be okay?
I'm thinking to finish off my suspension (for now) would be the Road Race K-Member, Boxed Lowers with Roto-Joints, and the Non-Adjustable Uppers with the Poly bushings. I drive on the street but am wanting to get back into some Auto-X with it this year. But I want the weight savings for when I drag race and the additional clearance to work on the car. So goodness all the way around.
