  • Offers compatibility with CIM or NEO motors

The AndyMark EVO Shifter Short Hex Shaft, StageA 3 - 45.33:1 Ratio 2:1, StageB 3 - 15.11:1 Ratio 2:1 represents a significant advancement in shifting transmission gearboxes. This two-speed, shift-on-the-fly gearbox incorporates an enhanced 4-tooth dog shifting mechanism, allowing for smooth and efficient transitions between gears. It is compatible with two CIM or NEO motors and can be configured with either two or three interior stages, offering flexibility in performance. The gearbox is shipped assembled, though motors are not included.

The design improvements include a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides increased strength and lubricity compared to previous stainless steel designs. The gearbox features a super-strong shift block assembly with a larger bearing and threaded steel housing, enhancing durability. The input stage utilizes 32 DP gears and a 15-tooth pinion gear, achieving a high first stage reduction of 85:15. Users can independently select high and low ratios and swap them as needed, providing greater control over performance.

The EVO Shifter employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder for reliable operation even under varying conditions such as acceleration or deceleration. The gearbox is designed with aggressive weight reduction features and includes various encoder options, such as the US Digital E4T. It can be mounted to an AM14U family chassis or a 2"x1" box tube frame using existing mounting plate holes.

Note: Ensure proper greasing and break-in procedures are followed for optimal performance and longevity of the gearbox.
