    upper a-arm length?

    i'm going to be bringing a ford front stub mod back to life (these are very similar to a late model front) wondering what length upper a-arms your late model cars are running. Everyone pretty much on the short RF upper? if so how short? how long on the lf?

      lot of lookers... any late model guys care to comment. i saw on the mastersbilt site they have anywhere from 7 3/4 to 9in looks like. Rocket didnt have all the options.

        depends on geometry and roll centers. GR is using i think 13 and 11 inch uppers, rocket has like a 10 3/4 and a 9". it just varies by brand.

          dont forget the latemodel guyts have different length lowers too, us modified guys are more limitied with having to run the stock lower control arms.....we have to run a way longer lf and shorter rf upper to get the same camber curves as a latemodel
