{"product_id":"5th-gear-set-658-ratio","title":"5th Gear Set .658 Ratio","description":"The Cascade 5th Gear Set is an aftermarket transmission upgrade featuring a .658 ratio, designed to replace the stock .756 TDI 5th gear. This popular modification is ideal for drivers who maintain highway speeds of 65-70 MPH, providing a typical RPM reduction of about 450 revolutions per minute. The gear set is manufactured in Germany and is compatible with 1990 and later 02A and 02J-based transmissions.\n\nWhen replacing your 5th gear, it is recommended to also change the gear oil and transmission seal. For installation, ensure the gear is heated to 100ºC during both removal and re-installation to prevent damage. Applying blue Loctite® to the small gear pinion shaft is also advised.\n\nNote that vehicles equipped with a BEW engine code may experience a loss of cruise control functionality unless this modification is paired with a compatible tune.","brand":"Cascade","offers":[{"title":"Default Title","offer_id":52687353119032,"sku":".658-5th-AFT","price":349.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660191738.jpg?v=1784883141","url":"https:\/\/store.motormia.co\/products\/5th-gear-set-658-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
