Systema Energy Torque Up Gear Set
With hollowed out structure, the sector gear employs the use of Dry Carbon Panels to reinforce the composition and with the addition of the highly reputable Chrome Molybdenum Steel cut motor pinion as a set, this allows a greater slow down ratio as compared to conventional models.
With a combination of this gear set and a Systema Energy Motor, the use of either the M120, M130 or M140 spring is the most suitable for maximum performance.
These gear sets already have shim adjustments completed for each gear. ONLY when using the Systema CMB case in conjunction with this gear set, shim adjustments are not necessary. For ALL other gear box cases, please read instructions or seek the help of an Airsoft Extreme gun tech for assistance.
