CE Smith Trailer Hub Kit 13110 - 1 Inch Spindle, 4 Lug x 4 Inch Bolt Circle, 1250 lb Capacity

The CE Smith 13110 Trailer Hub Kit is a preassembled, pregreased hub and bearing unit built for boat trailer axles with a 1 inch straight spindle. It is designed for a 1250 pound capacity and uses a four stud, 4 inch bolt circle diameter pattern, making it a common fit for standard single-axle boat trailers that use this bolt pattern and spindle size. The hub is constructed from alloy steel for durability under repeated launch and retrieval cycles, road vibration, and exposure to water and road salt.

Because the kit ships fully assembled with pregreased bearings already installed, it is intended to simplify trailer maintenance: instead of packing individual bearings, races, seals, and dust caps separately, the whole hub goes on the axle as one unit. The hub has a 1.98 inch inner diameter to fit correctly onto a 1 inch spindle axle, a 5-9/16 inch wheel flange diameter, and supports wheels up to 12 inches in maximum size. The kit includes a carry case, dust cap, cotter pin, and lug nuts, so the components needed to complete the installation are included rather than sold separately.

This hub kit is intended for buyers replacing a worn, damaged, or leaking hub and bearing assembly on a boat trailer, or for those upgrading to a preassembled unit to reduce maintenance time. It suits standard trailers using a 1 inch spindle and 4 lug x 4 inch bolt pattern rated to 1250 pounds capacity.
