SilverPath Posted June 15, 2014 Share Posted June 15, 2014 I have a 1999.0 with a manual tranny and 4.3 gears and 33s, suffice to say I wanted my umph back. I was looking at upgrading gears to say 4.9 so I could bring my highway manners and torque back close to stock. I was told I could simply use Xterra gears and move on with life, I recently came into possession of a front and rear R&P set in the 4.9 flavor. For starters, the Xterra and WD21 R200 front diff are a low pinion setup, this was the first big sign that they were not going to work, however being I had to swap in my lokka anyway we decided to dismantle my case and investigate further. The R50 gears are in fact reverse cut, however that is only because it is mounted in a high pinion setup, the axles still spin the same way when turned. Here is a X pinion and my R50 pinion next to each other for comparison sake. Link to comment Share on other sites More sharing options...
