Re-splined axles

Kim is right,If you are pushing 600-true and hooking up,I can't understand trying to save money on axles.No disrespect but maybe you could use them on the street with a little less horse?

No I wasn't trying to save money. I bought the rear this way. It's Mad Dart's 4 link he built for his pre-turbo setup. I'm going to be using 325/50/15 MT ET's so it should hook pretty hard. I don't know what the true hp this motor is pushing. It's a 15:1 416 motor with worked W2 heads.
