Many automotive components endure severe frictional forces and elevated operating temperatures. These facts are particularly evident in rear axles, where unfavorable conditions combined with the lack of proper break-in procedures lead to severe damage and efficiency losses. The ISF Process creates a smooth, micro-textured surface for enhanced oil retention properties and is metallurgically safe.Having GearFX apply REM's revolutionary ISF® Process creates parts that last considerably longer and perform better than standard components.
