The RetroArms CNC Split Gearbox Shell V2 QSC is a high-precision upgrade gearbox shell for Version 2 AEG platforms, engineered for advanced builders and techs who demand top-tier durability, modularity, and performance. Featuring CNC-machined 7075-T6 aluminum — also known as aircraft-grade aluminum — this gearbox is lightweight yet exceptionally strong, capable of handling high-stress builds.
This split design allows easy access to the upper section of the gearbox for quick maintenance, while the QSC (Quick Spring Change) system enables tool-less spring swaps without fully disassembling the gearbox — saving time and hassle during tuning or upgrades.
Ideal for serious builders running high-RPS, high-torque, or precision builds, the RetroArms CNC V2 gearbox shell is compatible with most V2 internal components and provides an unmatched level of rigidity and alignment.
