EVOLUTION STRAIGHT CUT 23 TOOTH 1275 PRIMARY GEAR

Modern EVO Straight Cut Drop Gear for 1275 Performance Builds

This Evolution straight cut 23 tooth primary gear is part of the latest Mini Spares EVO drop gear range, designed to bring classic Mini transmission parts up to modern performance standards.

Suitable for 1275cc A-Series applications, this gear helps improve transmission efficiency by reducing power loss through the gearbox and drop gears. It is ideal for performance road, competition, and high-output engine builds where strength and accurate gear matching are important.

Evolution Gear Design

EVO straight cut drop gears feature updated tooth profiles, shot peened finishing for extra strength, and two-ring identification markings. These improvements provide better durability and quieter operation compared with older straight cut designs.

Important Fitment Note

Evolution gears are not interchangeable with earlier drop gears, as they use a different tooth profile. They must be used only with matching EVO primary, idler, and input gears.
