Diff questions

I also recommend locking the tranny in second gear, it wont take long before you to break some tranny gears when that sudden power from a brushless motor slams the tranny when shifting from 1st to 2nd.

When the tranny is locked in second and the diffs are shimmed & aluminum diff cups the savage drivetrain is easily as strong as any buggy / truggy that I have used in my experience.

[_paralyzed_]

after all the upgrades (alum. cups, diff housings and bulkheads, 4 spiders shimmed) i found the weak link to be the pinion shaft bearings, they went and I ended up shearing diffs, I haven't had that problem since I ran bocas on the pinion, its the only place I use spendy bearings, but so far they've held up to the o.s. .30
