Rated for up to 750 horsepower, this kit aims to provide quick, crisp, and dependable shifts by incorporating vital improvements and carefully selected components that have been utilized by Dirty Hooker Diesel for over 15 years.\n\nThis kit addresses common durability issues, such as enhancing the C2 hub diameter with a steel sleeve and machining the P1 Sun gear to accommodate it. It includes all necessary bushings and bearings, complete pressure control and spring combinations (including Mike L Trim Springs), and precisely spec'd clutch stack heights. Buyers must confirm clearances during installation. Professional installation support is available post-purchase.\n\nThe kit includes a wide array of parts, such as a complete bushing and Torrington bearing kit, pressure control and shift valve upgrades, various clutch stacks (Alto G3, Raybestos GPZ, OE Borg Warner), new Allison filters, a modified converter flow valve, and billet components like the shallow filter lock and PTO covers. It also features new LML style C3\/C4 molded clutch apply pistons and return spring assemblies.\n\nTo achieve the kit's 750HP rating, an upgraded torque converter is required; the DHD 100-450 Goerend Billet Stator Triple Disc Torque Converter is recommended. Installation may also require specialized tools such as a C3\/C4 Return Spring Compressor and a DHD Pressure Control Spring Installer. This kit is specifically for 5-speed Allison transmissions and is compatible with 2001-2005 Chevrolet Silverado and GMC Sierra 2500\/3500HD models with the 6.6L Duramax engine and Allison LCT1000 5 Speed Transmission (Glove Box RPO CODE M74).","brand":"Dhd","offers":[{"title":"Default Title","offer_id":52687687057720,"sku":"100-550","price":1899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664192789.jpg?v=1784886108","url":"https:\/\/store.motormia.co\/products\/allison-5-speed-diy-builders-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
