{"product_id":"losi-los257007-4x8x3mm-ball-bearing","title":"Losi LOS257007 4x8x3mm Ball Bearing","description":"\u003cp\u003eThis is a set of four 4x8x3mm ball bearings, a precision rotating component used throughout Losi RC vehicles wherever a shaft or axle needs to spin smoothly with minimal friction, such as in gearboxes, wheel hubs, and drivetrain assemblies. Built with hardened steel races and shielded construction, these bearings are designed to keep dirt, dust, and debris out of the rolling elements while still allowing free rotation, which helps reduce drivetrain drag and extends the service life of surrounding components. Precision-ground tolerances keep runout low, supporting smoother power transfer and quieter operation compared to a worn or damaged stock bearing. As a genuine Losi replacement part, this bearing set is intended to restore worn-out or contaminated bearings to factory specification rather than serve as an upgrade over stock hardware. The bearings press directly into the original bearing bores using standard tools, making them a simple drop-in fix for routine maintenance across compatible Losi platforms. Four bearings are included in this package.\u003c\/p\u003e","brand":"Losi","offers":[{"title":"Default Title","offer_id":55906259075394,"sku":"LOS257007","price":16.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5063\/8402\/files\/LOS257007_A0_OGOQ97NQ.jpg?v=1786570534","url":"https:\/\/www.powerhobby.com\/products\/losi-los257007-4x8x3mm-ball-bearing","provider":"PowerHobby","version":"1.0","type":"link"}
