CE Smith Trailer Hub Kit 13515, Galvanized 1-3/8" to 1-1/16" Tapered Spindle, 5 x 4.5" Stud

The CE Smith Trailer Hub Kit (13515) is a complete, pre-assembled hub replacement for boat trailers, designed to take the mess out of bearing installation. Each hub arrives with bearings pre-greased and installed, so it mounts directly onto the axle without the usual pack-and-fit hassle. The kit is built with a galvanized finish that resists corrosion in the wet, salt-exposed conditions boat trailers regularly face.

This hub kit is sized for a 1-3/8" shaft that tapers to 1-1/16", with a 5 stud x 4.5" bolt circle diameter, making it a direct fit for trailers built to that hub pattern. It carries a 1750 lb capacity and is rated for wheels up to 15" in diameter. The hub itself has a 1.98" inner diameter and a 6-1/2" wheel flange diameter.

Everything needed for the swap is included in the box: a carry case for storage and transport, a dust cap to keep contaminants out of the bearing area, a cotter pin, and lug nuts. This makes the 13515 a practical choice for routine hub replacement or as a spare kept on hand for trailer maintenance.
