We recommend installing new Terache Super-Grip clutch discs with your gear reduction (only use Terache clutches or new OEM). Always remove the OEM crankshaft primary gear washer. 45% reductions include stiffer clutch springs. Always install the Terache primary gear thrust washer onto the crankshaft. Always use motor oil with a JASO-MA rating. Older air-cooled Foreman models require case modifications to fit these gears.\u003c\/p\u003e","brand":"Terache","offers":[{"title":"45%","offer_id":45447778238646,"sku":"TE-GRHC045","price":649.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0078\/7595\/2758\/files\/clutch-basket-billet45-updated.png?v=1789482157","url":"https:\/\/www.terache.com\/products\/nbs-45-billet-reduction","provider":"Terache","version":"1.0","type":"link"}
