[QUOTE="Martin #6, post: 1092138, member: 3300"] [b]3.55's to 4.10's[/b] I'm thinking of doing this gear swap also. Looking at a gear ratio calculator I'd be at 1866 rpm's doing 65 mph with my 34" tires. Do you think these rpm's are too high for sustained hwy driving and towing a 12k 5th wheel? Also will this range of rpm's increase my chances of water pump cavitation that I should be concerned with? [/QUOTE]
