WesB is right. I actually geared down to 2nd, rather than unlocking the coverter as usual. Its the first time I've really tried it. It helped me gain several feet, but its hard on parts. I knew I was playing with fire. The next night when I tried to do the same and as soon as I geared down to 2nd I busted the rear ring and pinion :doh: I was running 4.88s but decided to try out a set of 5.13s. Ordered a set for the front and rear today from Haisley. I wasn't really planning on making a gear change, but since the rear is broken and the 4.88s are so much more expensive than any othe ratio, I decided I'd try a different set.
