The NP205 has limited vulnerabilities but its compact size doesn't allow use of low gear sets. JB Conversions has a solution with its LoMax 205 Conversion. The LoMax 205 uses a nodular iron casting that features additional internal ribbing and a thicker case wall. The conversion also features a stronger-than-stock 3.0:1 gear set that uses wider-than-stock teeth. The LoMax 205 also retains the stock overall case dimensions.
