TII Pivot Ball Swap

My5ABaby · 08-06-2013, 07:04 PM

I'm about to swap in a S4 TII tranny to my boosted N/A and will be using an ACT HD PP/6 puck clutch. I've read that they can break pivot balls so I wanted to go ahead and replace mine to reduce that risk. I've read that the S5 ones are stronger and would prefer to use one, but have read conflicting information on whether I can or not.

So, can I use a (TII) S5 pivot ball in an S4 tranny?

Thanks!

Been using the hd pp for almost 20k miles now and have had no problems with the pivot ball on my s4 turbo trans. I think it's the extreme pp that causes pivot balls to break
