Hendrickson’s prototype HNP factory-installed trailer wheel end delivers a lightweight option ideal for flatbeds, dumps, dropdecks and other vocational trailers, the company says. Constructed of ‘austempered’ ductile iron, which is said to match aluminum for weight while delivering twice the strength, the HNP on Hendrickson P90 spindles provides the ability to switch between duals and wide-based single tires.

The HNP features a unique locknut system (patent pending), and with the parallel P90 spindle it provides even lubrication levels and requires only one standard bearing size. Furthermore, Hendrickson’s patented axle ventilation system protects against contaminants to enhance wheel-end life, the company says.

HNP units are pre-assembled and sealed in the factory to help ensure proper bearing adjustment, internal cleanliness, and seal performance.

HNP wheel ends will come with a limited five-year warranty for on-highway applications. They give truck operators one source for parts, service and warranty from suspension through wheel end, the company says. Plans call for a production launch next year. Contact Hendrickson at 866-743-3247.
