REM treatment results in a smoother surface. The end result is less friction, less heat, and less wear. Any machined part has high and low areas left over from machining, grinding, etc. Those high spots become the initial contact points which in turn can become localized hot spots. Those localized hot spots can take the temper out of the heat treated area of the surface and then become a pit. REM reduces that possibility.

Other benefits include elimination of stress risers on the edge of parts and less friction on any metal on metal surfaces.

Suffering from poor performance and reduced fuel economy resulting from oversized tires? A Nitro gear change will help get that performance and economy back! It is a common misconception that lower gears are only for hardcore off-roading, in actuality the average daily driven vehicle can see huge improvements in both performance and economy by properly matching their vehicles gear ratio to their tire size all while reducing strain on the vehicles drivetrain. We at Nitro Gear and Axle realize the difficulty for the average consumer or install shop to compile the list of parts and prices required when doing a gear change. To make it easier for everyone the experts at Nitro are introducing an industry first- Gear Packages for many popular 4x4 applications. One part number. One price.
