KIT RACE STEERING
The seat ring and steering ring are manufactured with import 40Cr steel ant its hardness reaches at 50-55HRC. Meanwhile, the steel ball is made with Gr15 bearing steel through special carbonizing processing, which makes the thickness of carbonized layer reach at>0.6mm and the surface hardness of the steel ball at 48-53HRC. The part is processed through import equipment while the proceeding is precise in order to ensure durability and smooth steering.
