HJ75 Diff Gear Ratio
Posted: Fri Aug 19, 2011 11:44 am
Hey guys, i'm looking up putting a set of 37's on my hj75 cruiser. just wondering if anyone has any idea what ratio diff gears i should use with this size tyre to get everything back to the factory (ish) ratio. its got 35's on it now and factory 4.11's and she lugs a bit uphill on the highway and the speedo is miles out (obviously). Nitro does 4.88's and 5.29's so i've been looking at these. cheers
