Slot Car Raceway is Australia's specialist slot car parts store.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eJP JP37 37T Gear\u003c\/strong\u003e is a precision slot car drivetrain gear designed for use with \u003cstrong\u003e3mm axles\u003c\/strong\u003e in both \u003cstrong\u003esidewinder and anglewinder configurations\u003c\/strong\u003e. With 37 teeth, the JP37 provides racers with a versatile gearing option for tuning the final-drive ratio of a 1\/32 scale slot car.\u003c\/p\u003e\n\n\u003cp\u003eWhether you're building a competition car from the ground up, replacing a worn gear or experimenting with gearing to suit a particular motor and circuit, the JP37 is a practical addition to any serious slot racer's parts collection.\u003c\/p\u003e\n\n\u003ch2\u003e37-Tooth Gear for 3mm Axles\u003c\/h2\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eJP37\u003c\/strong\u003e features a \u003cstrong\u003e37-tooth gear\u003c\/strong\u003e designed for \u003cstrong\u003e3mm axles\u003c\/strong\u003e. Its compatibility with both \u003cstrong\u003esidewinder and anglewinder\u003c\/strong\u003e drivetrains makes it particularly useful for racers who work across different chassis and motor configurations.\u003c\/p\u003e\n\n\u003cp\u003eThe 37T specification provides another gearing variable when setting up a car. Changing the crown gear tooth count alters the final-drive ratio and therefore the balance between acceleration, motor loading and theoretical top speed.\u003c\/p\u003e\n\n\u003ch2\u003eSidewinder \u0026amp; Anglewinder Compatible\u003c\/h2\u003e\n\n\u003cp\u003eUnlike gears intended for only one specific motor orientation, the \u003cstrong\u003eJP JP37 is suitable for both sidewinder and anglewinder applications\u003c\/strong\u003e. This gives builders greater flexibility when selecting drivetrain components for different chassis designs.\u003c\/p\u003e\n\n\u003cp\u003eFor anglewinder applications, ensure the gear is paired with a compatible anglewinder pinion and that the motor, pinion and crown gear are correctly aligned. Proper gear mesh is essential for quiet running, efficiency and long component life.\u003c\/p\u003e\n\n\u003ch2\u003eDesigned for 3mm Axles\u003c\/h2\u003e\n\n\u003cp\u003eThe JP37 is specifically intended for \u003cstrong\u003e3mm axles\u003c\/strong\u003e, making it suitable for slot car drivetrains using this larger axle standard. The correct axle diameter is critical when selecting a gear: a properly matched gear should run concentrically on the axle without excessive play.\u003c\/p\u003e\n\n\u003cp\u003eWhen installing the gear, ensure it is correctly positioned and securely fixed before running the car. Check lateral axle movement and gear mesh carefully, particularly on high-performance builds.\u003c\/p\u003e\n\n\u003ch2\u003e37T Gearing for Performance Tuning\u003c\/h2\u003e\n\n\u003cp\u003eGear selection is one of the most effective ways to alter the character of a slot car without changing the motor itself. The \u003cstrong\u003e37-tooth JP37\u003c\/strong\u003e can be combined with different pinion sizes to achieve the final-drive ratio required for a particular motor, tyre diameter and circuit.\u003c\/p\u003e\n\n\u003cp\u003eA larger crown gear relative to the pinion generally produces shorter gearing, increasing torque multiplication and acceleration while reducing theoretical top speed. Conversely, a smaller overall ratio generally favours higher theoretical top speed. The optimum gearing is ultimately determined by the motor, track, tyre diameter and class regulations.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eJP JP37\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e37-tooth\u003c\/strong\u003e slot car gear\u003c\/li\u003e\n\u003cli\u003eFor \u003cstrong\u003e3mm axles\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompatible with \u003cstrong\u003esidewinder\u003c\/strong\u003e configurations\u003c\/li\u003e\n\u003cli\u003eCompatible with \u003cstrong\u003eanglewinder\u003c\/strong\u003e configurations\u003c\/li\u003e\n\u003cli\u003eIdeal for 1\/32 scale slot car builds and race cars\u003c\/li\u003e\n\u003cli\u003eUseful for replacement, maintenance and gearing changes\u003c\/li\u003e\n\u003cli\u003eSuitable for performance-oriented slot car setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eJP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct code\u003c\/td\u003e\n\u003ctd\u003eJP37\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\u003ctd\u003eSlot car gear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTooth count\u003c\/td\u003e\n\u003ctd\u003e37T\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAxle diameter\u003c\/td\u003e\n\u003ctd\u003e3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor configuration\u003c\/td\u003e\n\u003ctd\u003eSidewinder \/ Anglewinder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScale\u003c\/td\u003e\n\u003ctd\u003e1\/32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eSlot car drivetrain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eGearing \u0026amp; Pinion Selection\u003c\/h2\u003e\n\n\u003cp\u003eThe final-drive ratio is determined by the relationship between the \u003cstrong\u003e37T crown gear\u003c\/strong\u003e and the mating pinion. For example, a 37T gear paired with a 10T pinion gives a \u003cstrong\u003e10:37 gearing combination\u003c\/strong\u003e, while a 12T pinion gives \u003cstrong\u003e12:37\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eWhen tuning a car, consider the motor's RPM and torque characteristics together with rear tyre diameter and track layout.
