The AndyMark EVO Shifter Short Hex Shaft, StageA 3 - 09.54:1 Ratio 2:1, StageB 3 - 32.74:1 Ratio 2:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox is designed to accommodate two CIM or NEO motors, offering flexibility in motor input. The gearbox is shipped assembled, though motors are not installed. It features a robust design with a 4-tooth dog shifting method, enhancing strength and durability. The dog gear is crafted from AMPCO® 18 Bronze, providing smooth shifting due to its lubricity. A new shift block assembly with a larger bearing and threaded steel housing further enhances its robustness.
The gearbox allows users to independently select high and low ratios, providing versatility in performance. It supports two or three interior stages, with an optional third stage offering additional ratio choices. The design includes aggressive weight reduction features, and the gearbox can be mounted to various chassis configurations. The EVO Shifter employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder for efficient shifting during acceleration, pushing, or deceleration.
For optimal performance, the gearbox requires proper greasing with Red Tacky Grease after a recommended break-in period. The gearbox's encoder ratio is 3:1 for two-stage versions, facilitating precise programming for encoders. The design improvements and material choices make this gearbox a robust and versatile option for various applications.
