Axles

I’m thinking of putting some insurance on my axles and not sure what to go with on my daily for the street class! It’s a 01 dodge with 32 spline up front, I am hoping to be in the 600-700hp range and got a Detroit locker in the rear that we made work with 355 gears. I think Haisleys up front my be over kill and Yukon maybe a cheaper route and be planny strong enough for me. In the rear I may go with haisleys but I’m not sure if I even need them there either?

Or I could get my stock stuff cryogenically treated and be ok?

If I used stock stuff I could use my 35 spline locker I got and wouldn’t have to buy a 37!

What do u guys think?

The proven setup all us limited pro stock guys that used to be 2.6 used to use for years was chrome-moly 35 spline stuff up front (Yukon) and 37 spline 300m in the rear from either Branik or Haisley or someone like that. The Yukons don't hold up in the rear. We would still break that stuff but it seemed to hold up best

I don’t know why you would upgrade at this point unless you have unlimited funds, but still a waste.

Well the main reason in the front I need to replace seals and got take diff out and thought it be a good time to put a locker in! And don’t really want to do what I did on the rear with stock axle size in case I step up later.

And I’m afraid if I brake a rear it will ruin my locker!

And the ones that has put a locker up front how does it do on the street?
