damn! so according to bobby long his axles are almost twice as strong as my birf elim kit!
Although I will never discrete an axle breaking machine in terms of marketability and live product demonstration, remember this is just a machine providing an increasing load to the shaft, which may or may not be the same as the actual loading characteristics of the shaft in service.
I am not discrediting the fact that higher numbers means higher yield strength, I am simply saying that in my opinion the only thing an axle breaking machine is good for in the public's eye is for marketing, people wanna see those numbers even if they don't know what it means. Also, was that a brand new D60 axle that was tested, or was it a wrecking yard axle with xxx,xxx miles on it? Regardless if it was new, if I only see a chart with numbers, as an outsider looking in, I would assume the Longfield is new and the D60 is used.
That means that the numbers just sold me in terms of marketing.
Having said this, if Marlin Crawler some day got a breaking machine would I fully use it to our marketing advantage? Oh you can count on it!
I just don't trust those numbers as much as I would a real world test in a real axle housing loaded beneath a real truck.
Do I believe a Bobby long 30-spline axle is stronger than a stock D60 axle? Despite what the numbers from the machine say, I really don't think so in my opinion. Both are very strong in deed, but its just the shear size difference that gets me.
I have NEVER been a fan of the birfield eliminator kit because I own a Toyota and I am going to keep Toyota style parts on it. This too means that I would choose a 30-spline Longfield over a D60 conversion ANYDAY
