This is our billet 40% gear reduction for the Honda Foreman 400/450. Internal case clearance/cutting needed for install. Our stiffer clutch springs are recommended for this reduction and can be found in the "Parts" section of the site listed as "300-450 Springs". **ES models will need a shift module to prevent electronic shift issues, also located in the parts section.
