{"product_id":"02a-02j-5th-gear-set-0-658-ratio","title":"02A\/02J 5th Gear Set, 0.658 Ratio","description":"The Aftermarket .658 ratio 5th Gear Set is designed as a significant upgrade for 02A- and 02J-based Volkswagen and Audi transmissions. It replaces the stock .756 TDI 5th gear to offer a more economical cruising experience. This popular upgrade typically results in a drop of around 450 RPM at highway speeds (65-70 MPH), making it an excellent choice for daily commuters seeking better fuel efficiency and a more relaxed driving feel.\n\nWhen replacing your 5th gear, it is recommended to also change the gear oil and transmission seal. For installation, it is crucial to heat the gear to 100ºC both during removal and re-installation to prevent damage. Using blue Loctite® on the small gear pinion shaft is also advised. Vehicles equipped with a BEW engine code may experience a loss of cruise control functionality after this modification unless the vehicle is also paired with a compatible tune that accounts for this change.","brand":"GearH","offers":[{"title":"Default Title","offer_id":52688539353400,"sku":"658gearset","price":525.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663176963.jpg?v=1784890729","url":"https:\/\/store.motormia.co\/products\/02a-02j-5th-gear-set-0-658-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
