Galvanized Corrosion Protection for Boat Trailers

Boat trailers face challenging operating conditions, including water exposure, road debris, humidity, and frequent temperature changes. These conditions can contribute to corrosion and premature wear of trailer components.

The C.E. Smith 13317 Galvanized Hub Kit features a protective galvanized finish designed to improve corrosion resistance and help extend the service life of the hub when properly maintained.

This makes it an excellent replacement option for boat owners who frequently launch and retrieve their vessels in freshwater or saltwater environments.

The C.E. Smith 13317 is designed for trailer applications requiring a 5-lug, 4.5-inch bolt circle and 1-1/16-inch straight spindle.

When correctly matched to the trailer's spindle, bearings, seals, and axle requirements, this hub kit helps restore dependable wheel operation for transportation to and from the boat ramp.
