Thanks, gents. 390 ratio might not be enough improvement to be worth swapping in a 55-62 pumpkin, unless there are some out there with a higher ratio? Or, since it would need spring mounts anyway is there a good 6 lug rear end the right width that would have a higher gear?
I could find a 54 torque tube cheap, but that means a torque tube, and still only a 390 ratio
Where is Mother Trucker, or someone who sells the ring and pinion kits nowadays?
