whats the point of a birfield eliminator kit???
all that is is a d44 that is narrow.
by the way mine is the 8 lug d44 and i have a 69.5 WMS to WMS. and i love it.
i have a great center of gravity and 12 inches of lift and i am going bigger and what not with bigger tires.
i dont think wider is goofy looking at all. wait till he gets his 37's on his d44 and it will not be wide enough.
here is an example. friend A has a toy axle with longfields, arb, 5:29's. he breaks 3 birfields in 3 trips. (2 longs and one stock) . his outer lugs on his tire measure 81 inches exactly what mine measures. he has 1.5 inch spacers. and the most back spaced 10 inch rims i seen. he also has 35x15.50x15's. and hes breaking birfields left and right. i also forgot he has hydro assist.
now my setup. d44 3/4ton 37x12.50x17. i have broken 2 ujoints an due to one ujiont and axle shaft. in the last year of about 15 wheeling trips. mine measures 81 inches outside lug to outside lug on out tires.
point being. you can make a toy axle wide with certain qualitys. like his truck. but you put so much stress on the birfs you tend to break them. as far as being too wide. well i think in 90 percent of trails and obstacles you want to be wide and a narrow light body.
unsprung weight is nice
by the way Friend A has a d60 up front now 69.5 wms to wms.
