The LoMax 205 transfer case truly stands in a class by itself. The original New Process 205 has always been recognized as The King of brute strength in transfer cases. The LoMax 205 retains all of the benefits from the original NP205 and goes several steps further. The LoMax case is a nodular iron casting machined to exact tolerances taken from the original New Process drawings. Aside from the stronger nodular iron recipe, the LoMax case offers more internal ribbing and wall thickness than the original NP205.
The 3:1 gear set offered in the LoMax transfer case is stronger than the original New Process gears. The tooth width is wider than stock yet the overall case dimensions are equal to stock New Process design. This means there are no modifications required to your truck. Driveshafts, shifters, etc. are retained in their original form.
Is 3:1 enough?
Consider going from 3.72 to 5.58 AXLE GEARS. This is the same percentage of gear reduction you are getting with the LoMax transfer case gears.
The chosen ratio of 3:1 was dictated by customer demand. Consideration was given to a 4:1 case however our customers were concerned over loosing too much wheel speed at the sacrifice of gear ratio. For this reason, 3:1 has proven to be the best ratio for all-around performance in the big truck class.
