i just picked up my super beefy shaft from RRO today. it was a couple bucks but well worth it since i am on my 8 or 9th broken or severely damaged u-joint on my rear shaft!!! this sucker had 6 inches of usable travel and is made of some heavy crap!! it probably weigh almost 30 lbs!!! anyway here is a pic , it has a ten spline slip yoke and these splines are huge for a samurai!!! the spline diameter is 2" and the whole shaft is almost the diameter of a spray paint can!!! big stuff with 1/2 ton u-joints!!
