84720FourWheel Posted April 1, 2015 Report Share Posted April 1, 2015 I was curious about any differences between the early hardbody axle and the 720 axle. I'm looking to invest in an ARB air locker, and don't want to drop a grand to see if it fits. http://store.arbusa.com/ARB-Air-Locker-Nissan-C200-R200a-29-Spline-All-Ratios-RD202-P3504.aspx This is the locker in question. Thanks in advance. 1 Quote Link to comment
ggzilla Posted April 1, 2015 Report Share Posted April 1, 2015 There are differences in the axle, but not in the differential. Quote Link to comment
84720FourWheel Posted April 2, 2015 Author Report Share Posted April 2, 2015 But the 720 axle is 29 splines and the same diameter as the hardbody axle? Quote Link to comment
datzenmike Posted April 2, 2015 Report Share Posted April 2, 2015 Both the 720 and the D-21 have C-200 and H-190 differentials. The 720 has 29 splines. I tried comparing the side gears that the axles slip into. I figured if they are the same, the axle has to fit. It was confusing as hell. The H-190 is the same for sure even up into the Xterra. My head started hurting and I had to stop. :lol: I can try again tonight after work. I will say it looked promising. Quote Link to comment
Stoffregen Motorsports Posted April 2, 2015 Report Share Posted April 2, 2015 The bast source of info for this question would be ARB. They sell a lot of these in the southern hemisphere. Quote Link to comment
84720FourWheel Posted April 2, 2015 Author Report Share Posted April 2, 2015 Sent ARB an E-mail (still waiting on a reply) but I figured somebody on here has dealt with swapping differentials out and would have some info. Quote Link to comment
84720FourWheel Posted April 2, 2015 Author Report Share Posted April 2, 2015 (edited) ARB replied with this: "I show a footnote to verify the ring gear bolts at 12mm for that diff and it may be that is why it is not listed for the earlier rigs. It is the right spline count and diff model though." This is in reference to the thread diameter. Anybody know offhandedly? Edited April 2, 2015 by 84720FourWheel Quote Link to comment
