The Smooth gear set utilizes integral 7mm ball bearings on all of the axle shafts. This allows you to achieve effortless revolutions on traditional non bearing bushing mechboxes. The Smooth gearset is compatible with reinforced gearboxes due to the newly engineered chassis/bracket system which allows for "pre-shimmed" drop in installation while not interfering with the reinforced gear area of the mechbox. The chassis features an ARC cut out which allows the bevel gear to conform to the position of the bushing holes in a variety of mechboxes. Includes: Modular Gear Set with 2pcs of 7mm Ball Bearing for each 3 gear, with Stainless Bushing*1/ Anti-reversal latch*1/ Gear Key*1 (Option) Compatible with Marui series Ver.2/Ver.3 gearbox. Including the reinforced Ver.2 gearbox
