Hub Seal Sportsman Hub

The Hub Seal Sportsman Hub from Coleman Racing Products is a precision wheel hub seal engineered for high-performance racing applications, particularly Wide 5 bolt pattern sportsman-class vehicles. This rubber and steel composite seal is designed for drivers and mechanics who demand reliable containment of bearing grease and protection against moisture and contamination in demanding track environments. Whether you're running a weekend warrior at your local dirt track or competing in sanctioned sportsman events, a quality hub seal is foundational to consistent wheel bearing performance and safety.

The Hub Seal Sportsman Hub features a dual-material construction combining elastomeric rubber with a steel reinforcing ring, a proven design that provides both flexibility and structural integrity under axial and radial loads. The seal lip geometry is optimized to maintain contact with the hub bore while allowing controlled bearing preload adjustment without excessive drag. Measuring 3.9 x 0.5 x 4.45 inches and weighing just 0.12 lbs, this compact seal fits standard Wide 5 hub applications without modification. The material composition resists thermal cycling, fuel exposure, and abrasion—critical concerns in racing where bearing temperatures can exceed 200°F and centrifugal forces stress traditional seals to their limits.

This hub seal is ideal for sportsman-class racers running Wide 5 bolt pattern wheels on dirt, asphalt, or drag racing platforms. Installation is straightforward: the seal seats into the hub bore ahead of the bearing assembly, creating a barrier that keeps grease in and debris out. Proper bearing preload and seal seating ensure extended service life between rebuilds. Mechanics should verify hub bore condition and cleanliness before installation, as surface irregularities can compromise seal effectiveness. Coleman Racing Products' reputation for manufacturing consistency makes this seal a dependable choice for competitors who cannot afford mid-season bearing failures.
