Maxima Copolymer GF4
This shiftknob is hand-made from solid acetal copolymer. This material is a hard plastic that will not absorb heat in the summer and won’t freeze in the winter unlike typical metal knobs. This provides an extremely comfortable knob all year long.
A cross between a piston and a sphere shape, the "GF4" style was designed by an early customer of mine, George Friedrich. This is the 4th iteration of the style, hence the initial name of the knob. This knob provides a vertical shifting position for your hand, while maintaining a curved ergonomic top for your palm to rest on.
A custom-made brass threaded insert provides more weight and stronger threads. This insert is automatically included on this item.
