{"product_id":"sequential-sequential-shifter-conversion-kit","title":"Sequential Sequential Shifter Conversion Kit","description":"The S1 Sequential R154 is a conversion kit designed to transform your standard Toyota R154 5-speed H-pattern gearbox into a true sequential operation. It provides repeatable, lightning-fast shifts, even under heavy racing loads.\n\nThis sequential shifter's push-pull design significantly enhances driver coordination during high-G maneuvers by making it physically impossible to select the incorrect gear, preventing costly mistakes like accidental 2-5 upshifts or damaging 5-2 downshifts. It offers precise mechanical feedback, a clear indication of gear engagement, a mechanical reverse lockout for added safety, and the ability to select neutral between any gear.\n\nKey features include a direct-mount design that attaches to the gearbox housing, not an extended factory bracket, which may require trimming the transmission tunnel for clearance. An optional Shifter Surround is recommended for a clean seal of this modification. Available upgrades include a Gear Position Sensor for data logging and gear-based boost control, a Digital Gear Indicator for dash display, and various lever options like the Direct High Lever and High Linkage Lever to adjust shift position while maintaining a short throw.","brand":"S1","offers":[{"title":"Default Title","offer_id":52689381523768,"sku":"R154","price":1699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687660523.jpg?v=1784905988","url":"https:\/\/store.motormia.co\/products\/sequential-sequential-shifter-conversion-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
