Manufacturer: Black Knight

Type: 4mm Shaft Gear Set

Includes: 4mm Gear Set 8mm Bushings And 4mm Shims

This gear set has a 4mm shaft instead of the standard 3mm. Because of this the 4mm shafts are a lot stronger then the standard 3mm. Also another advantage of 4mm shaft is the increased contact surface which greatly increases durability and reduces friction.
