***THIS REDUCTION REQUIRES ENGINE DISASSEMBLY AND MAJOR CASE MODS!
**Price includes a $50 core charge on the stock parts. Please send in your original parts and include a copy of the original purchase receipt for the core refund.
This is our billet 80% gear reduction for the Honda Foreman 400/450. Extensive internal case work (cutting and case welding) needed for install. Our stiffer clutch springs are also needed 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. Pic is an example and may not show the correct size.
