already have the slicks in my garage and i'm ordering the lsd for the tranny so the 4g63 will be able to hold up if i start boosting more??

 

The stock 7 bolt is good for 400-425 hp and the stock 6 bolt can handle 425-450 hp.

 

thats awesome but what are the stock axels rated at???

 

you shouldnt have any problems with the stock axles. But remember you cant get the lsd inserts because they suck, they wont handle more than . You must either get a quiafe lsd or go to sheptrans.com and get a fully built tranny
