Anyone a mortgage broker?
D60.....or D44? It depends on what you're doing......as well as how you are doing it. In a relatively lightweight rig with a mild V8 or smaller displacement engine, it would be more of a penalty than a benefit to run a D60 over the 44. If you can make a D44 live, it's no brainer to do so. With all other things being equal, the rig with the D44 will be more capable, faster, and economical than the one with a D60.......until it breaks, and alot of breakage issues can be avoided by upgrading the D44 to stronger aftermarket shafts, which is much cheaper than a D60.
I'm not knocking the 60, I want one.....but for 39s, I think it's overkill and a waste in most instances.
