I installed one of James' sheaves this summer. After speaking with him ordered the sheave, weights, and gold spring. I purchased the compression tool and went at it.
Easily the best modification I have have done to my Rhino. Off the line acceleration is much better, throttle response is improved, climbing feels much better. Really wakes the lazy throttle of the Rhino up.
James at JBS is a great resource and a top shelf guy to deal with. I even called him in the middle of my conversion, he took the time to make sure that I was doing it correctly, and gave me a couple of tips.
Had the work done in about an hour, and have not looked back. If you purchase one of James kits, you wont be disappointed.
