Part of the TH400 inefficiency results from the fact that the direct drum counter rotates, spinning backwards in 1\u003csup\u003est\u003c\/sup\u003e Gear, brakes to a complete stop on the 1-2 shift, then goes from 0 RPM to input RPM on the 2-3 shift. Significant energy is wasted through this cycle that robs power, upsets traction on the shifts and contributes to broken internal parts.\u003c\/p\u003e\r\n\u003cp\u003eCompared to aluminum direct drums, the Smart-Tech drum module reduces the weight of the counter-rotating components by over 3.3 lbs! And more significantly, because the weight of the Sonnax counter-rotating parts is closer to the centerline, there is a 68% reduction in energy required to stop and restart during the 1-2 and 2-3 shifts. The benefits are increased wheel horsepower, better acceleration, less shock on the shifts and improved durability.\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eComplete kit replaces both forward and direct drums and includes everything from intermediate sprag to the pump; a selection of inputs shafts is available separately\u003c\/li\u003e\r\n\u003cli\u003e100% new content, no used core pieces\u003c\/li\u003e\r\n\u003cli\u003eIncludes larger-diameter, 36-element sprag and sprag race that works with OE intermediate clutches\u003c\/li\u003e\r\n\u003cli\u003eIncludes six-friction forward clutch pack and seven-friction direct clutch pack\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"part-accordion cb spaced-vertical\"\u003e\r\n\u003ch2 id=\"components\"\u003e\u003cspan style=\"font-size: 12pt; color: #ff6600;\"\u003e\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents Include:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\r\n\u003cdiv\u003e\r\n\u003cdiv class=\"accordion-content\"\u003e\r\n\u003cdiv class=\"container\"\u003e\r\n\u003cdiv class=\"col-12 col-md-4\"\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eForward Piston Housing\u003c\/li\u003e\r\n\u003cli\u003eForward Piston\u003c\/li\u003e\r\n\u003cli\u003eForward Piston Return Springs (16)\u003c\/li\u003e\r\n\u003cli\u003eForward Spring Retainer\u003c\/li\u003e\r\n\u003cli\u003eForward Snap Ring\u003c\/li\u003e\r\n\u003cli\u003eO-Ring \u003cem\u003e1.674\"\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003cli\u003eLip Seals (2)\u003c\/li\u003e\r\n\u003cli\u003eDirect Housing Assembly\u003c\/li\u003e\r\n\u003cli\u003eDirect Piston\u003c\/li\u003e\r\n\u003cli\u003eSprag Retainer Screws (4) \u003cem\u003e6-32 x 5\/16\"\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"col-12 col-md-4\"\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eDirect Piston Return Springs (26)\u003c\/li\u003e\r\n\u003cli\u003eDirect Spring Retainer\u003c\/li\u003e\r\n\u003cli\u003eDirect Snap Ring\u003c\/li\u003e\r\n\u003cli\u003eO-Ring \u003cem\u003e2.737\"\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003cli\u003eSprag Shaft\u003c\/li\u003e\r\n\u003cli\u003eFront Sprag Retainer Plate\u003c\/li\u003e\r\n\u003cli\u003eHeavy Duty Sprag \u003cem\u003e36 Element\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003cli\u003eOuter Sprag Race\u003c\/li\u003e\r\n\u003cli\u003eRear Sprag Retainer Plate\u003c\/li\u003e\r\n\u003cli\u003eSteel Clutch Plates (4) \u003cem\u003e.060\"\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003cli\u003eSteel Clutch Plates (11) \u003cem\u003e.077\"\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv class=\"col-12 col-md-4\"\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eQuad Ring Seals (2)\u003c\/li\u003e\r\n\u003cli\u003eAnti-rotation Seal Rings (2)\u003c\/li\u003e\r\n\u003cli\u003eDrum\u003c\/li\u003e\r\n\u003cli\u003ePressure Plate\u003c\/li\u003e\r\n\u003cli\u003eOuter Snap Rings (4)\u003c\/li\u003e\r\n\u003cli\u003eBearing \u003cem\u003eSmall\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003cli\u003eForward Clutch Hub\u003c\/li\u003e\r\n\u003cli\u003eBearing \u003cem\u003eLarge\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003cli\u003eDirect Clutch Hub\u003c\/li\u003e\r\n\u003cli\u003eFriction Clutch Plates (13) \u003cem\u003e.080\"\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003cli\u003eClutch Separators (60) \u003cem\u003e.103\"\u003c\/em\u003e\n\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e","brand":"SunCoast Converters","offers":[{"title":"Default Title","offer_id":57273851347317,"sku":"34555-01K","price":3200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/7656\/2037\/files\/F198648894.jpg?v=1780954006","url":"https:\/\/wickeddieselva.com\/products\/sonnax-th400-smart-tech-drum-module-34555-01k","provider":"Wicked Diesel VA","version":"1.0","type":"link"}
