Gearbox Shell V2 QSC Retro ARMS
Gearbox Shell V2 QSC Retro ARMS (Quick Spring Change) is part of the "7075" gearbox series from Retro ARMS.

The gearbox is entirely made at high precision CNC machines. Compared to other aluminum gearboxes, Retro ARMS products are made of a solid block of aircraft aluminum (Dural) AW EN7075 T651 to enhance durability and corrosion resistance.

This type of aluminum is used predominantly in the aircraft parts industry, rockets, components such as valves, gears, fuses, but also for bicycle frames and terrain vehicles, because has higher strength (590MPa), than common construction steel (390MPa).

Therefore, an aluminium block of 1550 g molded at CNC machines turns into a gearbox shell of only 143 g.
The strength and durability of the material used in manufacturing these gearboxes has been tested with M160 springs without any signs of wear.

The gearbox is suitable for 8 mm bearings, the bearings are not included in the package.
Another advantage of these gearboxes is the QSC, Quick Spring Change system,that allows the user to change the spring without opening the gearbox.
