We have teamed up with JBConversions tobring you the absolute strongest parts currently available to make our complete Rock Box, Using our billet machined case and JB Conversions 32 spline shafts and 4:1 LoMax gear set.
JB Conversions 4 to 1 LoMax gear set has been designed to achieve maximum gear strength and the lowest possible reduction ratio for the Jeep Dana 300 transfer case. For over 2 years, the LoMax gear design effort has been an independent project of JB Conversions, Inc. and bears no affiliation with any other aftermarket gear manufacturer. The LoMax design features that set it apart from others are incorporated into all areas of the gears. Tooth volute shapes and face finish, gear hub thicknesses, and manufacturing tooling & processes yield a gear set far superior to any other gears being produced for the Dana 300. The LoMax gears were designed as a complete 5-gear "set" from the very beginning. This means there were no strength-limiting tooth size restrictions forcing the new gears to mesh with smaller stock gears. As you will see in the accompanying photo comparisons, the result of this "clean slate" philosophy is a set of gears with massive, helical gear teeth with tremendous strength capacity.
