Description
Prevent costly bearing failures and protect your wheel ends with this premium, heavy-duty unitized commercial hub seal.
The Traction private label HD Plus Part Number 1056HD (replaces Dexter factory code 010-056-00) is a high-performance, unitized trailer wheel seal engineered explicitly for maximum-duty commercial operations. Featuring a two-part rubber and metal body construction, the internal sleeve stays locked to the spindle surface while the outer casing rotates seamlessly with the hub. This specialized design prevents typical seal-walk, reduces friction wear, and guarantees airtight oil-bath retention inside heavy-haul trailer hubs.
