SCS QUICK CHANGE GEAR SETS SCS Professional Series Quick Change Gears are made from aircraft steel for maximum strength. Each gear has a shaved finish to minimize backlash and run out, and is broached for proper 10 spline shaft fit. The SCS Extra 5 step heat treating process yields maximum gear life for high stress applications. Gears have a black oxide finish, and the faces have been lightened to reduce rotating weight without sacrificing strength.
