Right now my Crown has a 4.68 ratio rear end and I want to improve my milage and top speed. The lowest ratio I've seen is 4.11. Although this would help it isn't the increase I want. Is it possible to find something around 3.75 or do I need to go for the 4.11 and change my 24" tires to 26"?
I have a Cummins 220 with a turbo added (should be about 262hp now) and a Roadranger 10 speed. |
