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:

Nitro Gear and Axle's complete 4.88 gear kit is designed to improve performance and fuel economy for the 2007-Current Toyota Tundra.

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.

The Tundra has a very tall overdrive in 5th AND 6th gear to turn low RPMS. If you are running 33” or larger tires, the 6th gear becomes near useless and all that great horsepower the 5.7L makes can be wasted. This also causes constant shifting, poor economy, and poor acceleration. By regearing you can bring the motor back to the RPM it was intended to run. This will improve Economy, Performance, and shifting. This is one of the most important modifications you can make after installing larger tires on your late model Tundra. This is the only way to properly compensate for the increase in tire diameter.
