C.E. Smith Hub Kit 5x4 1/2" 1" to 1-1/16" Tapered Spindled 1.79" Seal - 13517

C.E. Smith Hub Kit – 5 x 4-1/2" Bolt Pattern, 1" to 1-1/16" Tapered Spindle, 1.79" Seal – 13517

Keep your boat trailer rolling smoothly with the C.E. Smith Galvanized Trailer Hub Kit (13517). Designed for trailers equipped with a 5 x 4-1/2-inch wheel bolt pattern and a 1-inch to 1-1/16-inch tapered spindle, this replacement hub kit offers a durable solution for maintaining your trailer's wheel hub assembly.

Featuring a galvanized finish, the C.E. Smith 13517 provides corrosion resistance for demanding marine trailering environments. Whether you're transporting your boat to the lake, launching at a coastal ramp, or performing routine trailer maintenance, this hub kit is designed to withstand the challenges associated with repeated water exposure.

The hub is specifically configured for a 1-inch to 1-1/16-inch tapered spindle with a 1.79-inch grease seal inner diameter. These dimensions are essential for proper fitment, helping ensure compatibility with the trailer axle and wheel assembly.

A reliable wheel hub is an important part of safe and efficient trailering. Replacing worn or damaged hubs can help restore proper wheel rotation and reduce the risk of bearing-related problems when the complete assembly is correctly installed and maintained.

The C.E. Smith 13517 Galvanized Hub Kit is an excellent choice for boat owners, trailer repair shops, and marine service professionals looking for a replacement hub with precisely specified spindle and seal dimensions.

The galvanized construction, bolt pattern, spindle configuration, and seal dimensions are confirmed in model-specific product listings.

Product Specifications

Trailer Hub Compatibility

Before purchasing, verify the following measurements on your existing trailer:

Important: Matching the wheel bolt pattern alone does not guarantee compatibility. Confirm spindle bearing journal dimensions, grease seal size, hub length, bearing specifications, and axle load requirements before installation.

The manufacturer-specific package breakdown was not confirmed in the available listings. Verify whether bearings, races, grease seal, dust cap, lug nuts, cotter pin, and grease are supplied before installation. Do not assume components included with other C.E. Smith hub models are included with this specific kit.

Why Choose the C.E. Smith 13517 Galvanized Hub Kit?

The C.E. Smith 13517 combines application-specific fitment with a galvanized finish that is especially useful for boat trailers regularly exposed to wet conditions.

Its five-lug bolt pattern accommodates compatible trailer wheels, while the tapered spindle configuration and 1.79-inch seal specification help simplify replacement selection.

For boat owners performing preventive maintenance or replacing a damaged hub, choosing the correct assembly helps maintain reliable trailer operation and protect critical wheel-bearing components.

The galvanized finish also offers an advantage over basic painted hubs in environments where moisture exposure is common.

Installation Note: Inspect the spindle for scoring, heat damage, or excessive wear before installing a replacement hub. Use the correct bearing components and grease, follow the applicable bearing adjustment procedure, and torque wheel lug nuts to the trailer or wheel manufacturer's specifications. Verify the assembly's load rating before towing.
