{"product_id":"six-speed-builders-kit","title":"Six Speed Builders Kit","description":"The Ultima\/Midwest Six Speed Builders Kit (P\/N: 98-902) is designed to upgrade Big Twin motorcycles from a 5-speed to a 6-speed transmission. This kit is compatible with most 1990-1999 models with minimal or no modification required.\n\nThe kit provides a 6-speed gear ratio with specific ratios including 1st gear at 2.94:1, 2nd at 2.21:1, 3rd at 1.57:1, 4th at 1.23:1, 5th at 1:14, and 6th at 0.86:1.\n\nInstallation considerations include the need for a speedometer recalibration unit on some 1996-2000 and all 2001 and later models. For 5-speed type 2000\/Later models, additional minor modifications may be necessary. The trap door on this kit is thicker than stock, potentially requiring modification for any trap door-mounted brackets. Additionally, all Touring FLT and FLH Models from 1993 onwards require an oil filler spacer (#89-14).","brand":"Ultima","offers":[{"title":"Default Title","offer_id":52664039637304,"sku":"98-902","price":664.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687157675.jpg?v=1784332329","url":"https:\/\/store.motormia.co\/products\/six-speed-builders-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
