Yup. Those go in the diff, and you’ll want to have some grease in hand but that’s it.

How about the portal OD gearset? Or will that be too much?
Together??
Anyone know what?

Lots of options since there are 3 different portal gear ratios available now, so you can really fine tune how much OD you have. I feel like 20-25% is the magic amount of OD for me, and since I already have OD R&P, adding HR portal gears would put me in the zone. GeorgeNada made a handy chart for comparison's sake (I ommitted the Capra transmission part of his chart):

Thats exactly where I was going.....I thought by using two I could get the higher OD, exactly as you've done

That list of gearing is nice, but it's for the Capra so it doesn't take into account the transmission gearing for straight axles in the SCX10 III. So another section could be added for those gears as well.

Did Both the axial and HR portal. I'm now running at 23%...seems perfect with my stubby. I did go to 70wt in the rear shocks, this now climbs fantastic
