The 29-tooth count offers a balance between acceleration and top speed in electric builds such as drag cars, buggies, and trucks. Machined aluminum construction reduces rotating mass compared with heavier steel gears, helping the motor spool up quicker under throttle. Precision cut 48P teeth ensure smooth mesh engagement with matching spur gears for efficient power transfer in performance-oriented setups.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e48 Pitch with a 5mm pinion bore for larger 4-pole drag motors\u003c\/li\u003e\n\u003cli\u003eMachined from aluminum and given a hard anodized for durability\u003c\/li\u003e\n\u003cli\u003eEtched tooth size for easy identification\u003c\/li\u003e\n\u003cli\u003eLess rotating mass\u003c\/li\u003e\n\u003cli\u003eQuicker motor spool up\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ProTek RC","offers":[{"title":"Default Title","offer_id":49798151274783,"sku":"210000017818","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/0426\/8063\/files\/lagthxgy1xbcvetjaw5l.jpg?v=1731623459","url":"https:\/\/newsunracing.com\/es\/products\/ptk8649-48p-lightweight-hard-anodized-aluminum-pinion-gear-5-0mm-bore-29t","provider":"New Sun Racing","version":"1.0","type":"link"}
