i finally found a place to make stronger shafts for my 04 silverado so i can put bigger tires on it. correct me if i'm wrong but i was told that with 35" tires and any power these things break alot from what i've been told. has any body found a place to make stronger shafts. they said they should be good for 750whp. something about 300mm chromoly steel shafts and something else didn't catch it all i was just happy when i heard yes i can do it and 750whp. any thoughts on this??
