The 2.25\" ball gives a noticeably stiffer, more confidence-inspiring hold — especially important on boats that run in rough water or at higher speeds. It's also the correct base when a customer is replacing or expanding an existing D-series RAM setup. Always confirm the customer's arm is a D-series before ordering — the 2.25\" ball is not compatible with standard 1\" or 1.5\" ball arms.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199445139492,"sku":"170-RAMD202U","price":63.89,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/170-RAM202_7949d9c3-f8da-475e-8af0-1d4ed9c470b3.jpg?v=1785605540","url":"https:\/\/marisolmarine.com\/products\/ram-ramd202u-2-5-round-base-2-25-ball","provider":"Marisol Marine Company","version":"1.0","type":"link"}
