Modern Muscle Xtreme doing the heavy lifting on getting this new Smith Innovation gear drive tested.

It’s already made a 7k rpm pull and performing flawlessly. More pulls coming up next week and then a check of the gear wear. BTW, it’s not crazy loud like some have claimed it would be.

I will step aside and let MMX post up video when they are ready. We are very excited about this product and the new products in our pipeline. It’s a good time to be a Hemi guy/gal.
