I am getting ready to but a set of superior axles and ctm u joints for my rig and was wondering if it would be worth it to step up to 40 spline inners? My rig has a 79 ford high pinion Dana 60 under it. I already bought new bearings and brakes for the front end so i want to stick with 35 spline outters for now but i am going to buy a new ARB. I want to know if it would be wise to buy the 40 spline ARB ( extra 400$) and forty spline inners that way if i do start breaking stub axles i will just have to buy the forty spline outters, hubs, spindles etc but not a new lockers or inners? is there any extra work if i buy 40 spline inners and 35 outters? do i have to change anything besides the locker for the new inners? Will this make the outters weaker than normal?My rig is a single seater with a real healthy big block chevy, 250 shot of NOS, Turbo 400, ORD doubler and 49" Iroks. I also really like the skinny pedal.
