The 5 mm bore fits directly onto standard 5 mm motor shafts found on many 1\/10 and 1\/8 scale electric cars, trucks, and buggies, allowing secure attachment with the included set screw. Heat treatment and nitriding of the steel improve surface hardness and corrosion resistance, which increases wear life under the high torque demands of brushless power systems. The gear’s tooth profile and pitch are engineered for smooth, consistent power transfer while minimizing drivetrain lash and noise. Face width and overall length are designed to clear motor housings and maintain proper mesh without interfering with adjacent components. Installation only requires aligning with the spur gear, seating on the shaft, and tightening the set screw with a hex wrench, with optional thread locker for added security. This pinion is suitable for tuning gear ratios to balance acceleration, top speed, and motor load in competitive or recreational setups.\u003c\/p\u003e\n\u003cp data-start=\"1196\" data-end=\"1914\"\u003e• 25 tooth 32 pitch gear matched to standard 32 DP spur systems \u003cbr data-start=\"1309\" data-end=\"1312\"\u003e• CNC machined hardened steel for durability and wear resistance \u003cbr data-start=\"1414\" data-end=\"1417\"\u003e• nitrided finish increases surface hardness and corrosion resistance \u003cbr data-start=\"1524\" data-end=\"1527\"\u003e• 5 mm bore fits directly on most electric motor shafts \u003cbr data-start=\"1620\" data-end=\"1623\"\u003e• included M4x4 mm set screw for secure mounting \u003cbr data-start=\"1709\" data-end=\"1712\"\u003e• optimized face width for smooth mesh and minimal interference \u003cbr data-start=\"1813\" data-end=\"1816\"\u003e• suitable for tuning performance and replacing worn gears\u003c\/p\u003e","brand":"Hot Racing","offers":[{"title":"Default Title","offer_id":49776637083935,"sku":"210000007983","price":10.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/0426\/8063\/files\/eslsnqz1faxkk7frxmvd.jpg?v=1757150063","url":"https:\/\/newsunracing.com\/products\/nsg3225-25t-32p-5mm-pinion","provider":"New Sun Racing","version":"1.0","type":"link"}
