{"product_id":"losi-los3691-motor-mount-insert-13-21","title":"Losi LOS3691 Motor Mount Insert 13\/21","description":"\u003cp\u003eThese motor mount inserts are precision-engineered replacement components for the Losi 5IVE-TE 3.0 platform, designed to work with a 67-tooth spur gear. Machined from 6061-T6 aluminum, the inserts feature 13 and 21 tooth mesh positions that let racers fine-tune pinion gear spacing and gear mesh without swapping the entire motor mount assembly. Proper gear mesh is critical on high-torque 5IVE-TE builds, since excess slop accelerates gear wear while too tight a mesh causes binding and heat buildup; these inserts let owners dial in the correct spacing for smooth, efficient power transfer. The 6061-T6 aluminum construction offers strong resistance to the vibration and heat generated by the electric drivetrain, holding its shape and position over repeated use where lower-grade materials can deform. This is a direct factory-spec replacement matched to the original 5IVE-TE 3.0 motor mount design, not an aftermarket redesign, so it installs using the stock mounting hardware and hole pattern. The package includes four mounting inserts along with the hardware needed for installation, giving builders everything required to complete the swap in one step. This part is ideal for maintaining consistent gear mesh on a 5IVE-TE 3.0 running the 67T spur gear setup.\u003c\/p\u003e","brand":"Losi","offers":[{"title":"Default Title","offer_id":55906281849154,"sku":"LOS3691","price":24.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5063\/8402\/files\/LOS-3691_A0_979CR71S.jpg?v=1786573075","url":"https:\/\/www.powerhobby.com\/products\/losi-los3691-motor-mount-insert-13-21","provider":"PowerHobby","version":"1.0","type":"link"}
