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.

PRODUCT OVERVIEW:

Designed for the 2011-2019 Chevy/GMC 2500 and 3500. A Nitro gear change will help get that performance and economy back!

If you've fitted larger tires to your vehicle then you are likely experiencing a loss in performance, fuel economy, and more constant transmission gear “hunting" - This is because the larger tires reduce your engine's RPMs below the optimal power band. Re-gearing the differentials in your vehicle is the only way to get your vehicle back into its optimal operating RPM range, thus improving performance and reducing strain on your vehicle's drivetrain. This is especially important for today's vehicles as they feature tall factory gearing and overdrive transmissions which are less tolerant to increase in tire size or the weight of added accessories.
