{"product_id":"aisin-az6-6-speed-gearset","title":"Aisin AZ6 6 Speed Gearset","description":"The Speedtek Auto Racing Aisin AZ6 6 Speed Close Ratio Dog Engagement Gearset is engineered to upgrade the performance and reliability of the factory Aisin AZ6 transmission found in Mazda MX-5 and RX-8 models. This comprehensive kit addresses common weaknesses in the stock gearbox, providing all necessary proprietary components. Included are gears, shafts, dog rings, hubs, a specific input shaft for the application, a main shaft, and specially designed custom bearings in key areas.\n\nThe gearset is constructed from Billet 6061 Aluminium and is designed for rapid, quick shifts, offering a distinctly different driving experience compared to the stock synchronized transmission. The kit features a close-ratio gearset with the following ratios: 1st: 2.88, 2nd: 1.97, 3rd: 1.52, 4th: 1.25, 5th: 1.00, and 6th: 0.85. This differs from the stock MX-5 6-Speed ratios (1st: 3.70, 2nd: 2.19, 3rd: 1.54, 4th: 1.17, 5th: 1.00, 6th: 0.83) and includes a reverse ratio of 3.43.\n\nDesigned for ultimate strength and performance, this gearset is rated to withstand up to 600 BHP (measured at power to the transmission). A race-spec lockout shifter, which prevents accidental engagement of first gear when shifting from second to third, is also part of the offering. The company offers a solid 6-month unconditional warranty on all manufactured gearsets, with an extended warranty program available. Pre-orders are strictly non-refundable, and completion is estimated for mid-2026.","brand":"Speedtek Auto Racing","offers":[{"title":"Default Title","offer_id":52866384396600,"sku":"AZ6DOGKIT-MX5","price":4725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687687962.webp?v=1787906948","url":"https:\/\/store.motormia.co\/products\/aisin-az6-6-speed-gearset","provider":"MOTORMIA","version":"1.0","type":"link"}
