Billet input shaft in aftermarket Transmissions...Needed?

[blackcloud2k]

Im getting ready to do a full rebuild on the tranny in my truck. The truck has 80k miles on it of hard towing at slow speeds up and down oil field roads. It is starting to slip more than I would like it to. The question is, are you guys putting billet input shafts in, or is the stock input shaft good enough? Im going to be going with the suncoast super duty rebuild kit, suncoast converter, with mag hytec deep pan, and additional tranny cooler. Just didnt know if I should spring for the billet shaft or not. Thanks.

I have sun coasts billet input and would recommend it. For the price why not upgrade it.

Thats the way I was looking at it, its pretty cheap so why not do it. But I figured it the stockers were holding in these trucks running 275 and 310 tunes then I might just save the money on the shaft and throw an airdog 2 under the truck. Anyone else have any opinion on this?
