How we measure Spring Forks. NOTE: Measurement is from the triple tree where stem and lower bearing sits  to the axle position. This is the effective length  as it is the legnth from the lower bearing cup on the frame to axle. Installer can slide a pipe or solid bar thru the bearing cups and measure the length that may be needed for the desired frame height. This Spring Fork assembly accepts a 3\/4inch axle for custom applications. As rockers are not offset (as on replica Spring Forks). 1inch stem utilized tapered bearings for ease of installation. *NOTE: UPS may consider this part as packages inchoversizeinch for shipment  as compared to the actual weight  which will result in higher shipping costs. \n\u003cbr\u003e Instructions: http:\/\/www.vtwinmfg.com\/Instructions\/49\/49-2402.pdf\u003c\/p\u003e","brand":"V-Twin","offers":[{"title":"Default Title","offer_id":67611421966521,"sku":"49-2402","price":3373.99,"currency_code":"USD","in_stock":false}],"url":"https:\/\/www.thespeedshopusa.com\/products\/18-inch-inline-spring-fork-assembly-black","provider":"THE SPEED SHOP USA","version":"1.0","type":"link"}
