Upgrade your boat trailer setup with the CE Smith 4-Inch Bow Roller Assembly Kit, designed specifically to fit 4-inch wide mounting brackets. This all-in-one replacement kit features a heavy-duty 4-inch black thermal plastic rubber bow roller paired with matching 4-inch end bells to cushion your boat's hull, guide it smoothly onto the trailer, and protect against marring during loading and unloading.
 
Complete with high-strength mounting hardware—including a 1/2"-13 x 6" zinc-plated hex bolt, two hot-dipped galvanized flat washers, and a 1/2"-13 Magni-coated nyloc nut—this durable assembly delivers long-lasting corrosion resistance in harsh marine environments.
 
Pro Tip: Always measure the exact inside width between your bow roller mounting supports before ordering to guarantee a seamless fit.
