This 4-speed transmission comes completely assembled with all gears  shaft and covers intalled for a quick straight-forward installation. It accepts original primary drive with clutch and the chain sprocket cover. Looks the same as a 3-speed unit  the only extra part required is a 4-speed shifter gate. The original 3-speed transmission has a large gear ratio difference between 1st and 2nd  (2.47 to 1.57:1) with a consequent big rpm drop. The 4-speed version with its extra gear allows you to stay in the power band  which is much better for performance. The shift pattern is: 1st gear is forward  neutral  3rd and 4th gear are back towards driver as seated on motorcycle. \n\u003cbr\u003e Tech Notes: Suggested to use with #18-0782  45 Clutch Pack Kit Suggested to use with #21-0894  Servi-Car Shifter Rod Kit\u003c\/p\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n1941 Harley Davidson G\u003cbr\u003e\n1941 Harley Davidson WL\u003cbr\u003e\n1942 Harley Davidson G\u003cbr\u003e\n1942 Harley Davidson WL\u003cbr\u003e\n1943 Harley Davidson G\u003cbr\u003e\n1943 Harley Davidson WL\u003cbr\u003e\n1944 Harley Davidson G\u003cbr\u003e\n1944 Harley Davidson WL\u003cbr\u003e\n1945 Harley Davidson G\u003cbr\u003e\n1945 Harley Davidson WL\u003cbr\u003e\n1946 Harley Davidson G\u003cbr\u003e\n1946 Harley Davidson WL","brand":"Motorshop","offers":[{"title":"Default Title","offer_id":55915580031144,"sku":"17-5500","price":6279.95,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/8273\/6552\/files\/17-5500a.jpg?v=1787813971","url":"https:\/\/speedguyscanada.com\/products\/45-w-4-speed-transmission-gear-assembly-unit","provider":"THE SPEED GUYS CANADA ","version":"1.0","type":"link"}
