Yea pretty much. The rear bearings on the b shafts don't get much oil so at high milesif you don't change the bearings out plan on them failing. I didn't change mine when I rebuilt my motor cause I'm an idiot and they failed. The failure smoked the rear journal on the pass side b shaft so instead of paying to get it fixed at the machine shop I just got rid of the b shafts all together. I was able give a before and after comparison and IMO I feel like my truck is faster off the line. 1st and 2nd gear are a lot nastier than they use to be but I don't have dyno proof on the matter so I can't really sit here and argue about it it's just my opinion. So yes I guess the delete something guys do for race motors or if they're just
out of luck and poor. Less moving parts is good too.
