spc performance upper control arms
 

Any one running this control arm on c10. The muscle car guys are love them. I want to see if anyone had any input. im looking at getting a set. They will fix all the bump steer and caster issue.

Caster possibly but how are they supposed to help bumpsteer?

Re: spc performance upper control arms
 

caster and camber from their web site

In a car, yes. The truck set-ups would be different. Do they now make them for the C10 applications? (I have the SPC upper arms/Stage-2 set-up for a G-body).

they don't show it but they do you have to call them and talk to the application guys in the back office. you have to order it in a cpl of pieces. cross shaft is #93400 which is a 5" mounting hole which is what mine measured out to. You will also need #92021 which is all the hardware for one with delrim bushings. ball joint plate is a 94004 for gm truck which is the bolt in one, that the same one you can get for the 1' tall ball joint too. then its math. we both did that and we can up with need a 5" adjuster for the rear and a 6" adjuster for the front which is 92050 and 92060.

I got approx 7° caster w/stock upper truck arms & shifting the lower BJ forward. I guess the SPC arms would work too.

Re: spc performance upper control arms
 

how did you shift it forward. are you on springs or air ride.

Re: spc performance upper control arms
 

I originally re-drilled the locating divot on the lower shaft to push the lower arms forward .750". The I went to bags but the pockets I made in the lower arms were too close for comfort. So I purchased a set of Porterbuilt 1" forward Lower arms to speed the process.

Re: spc performance upper control arms
 

so do you have stock upper arms. if so can you send me a pic of your ride height and then one with the air out.

They're on my build thread in the 73-87/builds sub-forum (my 89 CC project double wide).
