I was told if I re-gear to 5.29 and run 37's than my top speed in the truck will be only about 40 mph. Is this true? If it is there is no way im going to gear it that ratio becuase i am often on the highway and need to be going anywhere from 65 to 70 mph.
If you install 5.29's, and run 37's, you will be within 1% of stock gearing. Assuming your truck came stock with 4.10's and 29" tires from the factory.
Based on this assumtion, your gear set will give you a 29% reduction, and your tires will be 28% oversize, which trnaslates into 1% reduction in gearing from stock.
