mossy74 Posted December 9, 2008 Share Posted December 9, 2008 I'm going to buy a quaife lsd for my R180 but I need to know what ID ring gear I have, I'm pretty clueless with this sort of stuff so is there an easy way to measure this?

zcarnut Posted December 9, 2008 Share Posted December 9, 2008 What you need to measure is the circle diameter of the ring gear [securing] bolt pattern. This is not the ring gear outside diameter measurement. Nissan changed the bolt circle diameter of the R180 ring gear from the 110mm to115mm in August of 1976. Since the LSD differential housing bolts to the ring gear the R180 LSD changed as well. In addition the method of securing the axle shafts into the LSD changed from a bolt to an internal C-clip.
