Those videos really do belong on BYT, Im sure the guys would appreciate seeing how powerful BL power is when its done right- love that truck.

I'm not sure if a bushing would work better or not. We're dealing with really huge side AND thrust loads at that point.

Thanks for the Compliements.

I'm trying to reprocess on the setup actually. Is there a way to eliminate the ring and pinion? We've just about eliminated everything else with this setup.

How about a center mounted motor that spins the front and rear spider cups with a ribbed drive belt? Such as seen in alot of on road cars. I wonder how tough the belt setup is?

Hmmmmmmm.............thinking thinking

I am sure that the secondary drive belt from a harley would be able to hold up to the power, may be a bit overkill though...

You could do a chain drive, put some hardened steel spur gears on the diff cups, and use a bicycle chain, that is the correct size (would have to be smaller than the bicycle chain, but you get the idea). Then drive the center of the chain with another steel gear that mount to the motor. Only problem may be the sizes of the gears. You currently have 10/43 gearing. Finding a slightly larger steel spur for the diffs will not be an issue, a 46 would work and not be too big. But you would have to use an 11t pinion on the motor and somehow make sure the chain would stay in contact, maybe some spring loaded idlers? Sounding kind off complicated now. Maybe investigate the possibility of a needle roller bearing in the correct size?
