The AndyMark EVO Shifter am14u Family Hex Shaft, StageA 3 Stage - 06.86:1 Ratio 1.14:1, StageB 3 Stage - 12.41:1 Ratio 1.14:1 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 seamless 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 output shaft selection.

The gearbox features several improvements over previous models, including a robust 1/8" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides added strength and lubricity. The shift block assembly is reinforced 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 gear ratios, with the option to swap between them as needed.

The EVO Shifter employs a pneumatic shift method, powered by a spring-extend pneumatic cylinder, allowing for gear changes even during acceleration or deceleration. The gearbox is designed for easy assembly and disassembly, with cluster gears featuring identical characteristics on both sides. Weight reduction features have been integrated into the gears and plates, optimizing performance without compromising strength.

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