I think @Bighead440 would disagree. He's the friend I was talking about in my previous post. I tagged him so maybe he'll chime in. There are strength differences, but the 8 1/4 is stronger than you quote. He has pictures to prove it. 350HP won't hang the tires in the air.
I’m just going off of what the suregrip unit is rated for that Dr. Diff sells. I’m sure you could always build a stronger one but you will probably have alot more money and customs parts involved.
