Product Configuration

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.

The 2016 & Newer Tacoma is a fantastic vehicle, the new engine packs a punch into a fairly small displacement, and needs RPM's to operate efficiently and at peak performance. We have found the factory gearing to be inadequate even on stock vehicles in many cases. By re-gearing your diffs with a Nitro Gear Package you can restore performance and economy by optimizing the RPM range your engine runs at. We've already provided gears for hundreds of the 2016+ Tacoma, with excellent feedback and reports of much better drivability, performance, and economy. Many say that they love that their truck is not constantly shifting, and just feels “right".
