Description
Product Overview
The telfair Front Strut Hub Seal Sleeve is engineered as a premium replacement component for the front strut assemblies of utility terrain vehicles (UTV), side‑by‑side (SXS) and all‑terrain vehicles (ATV). Constructed from high‑grade steel with a precision‑machined inner surface, the seal provides a robust barrier against contaminants while maintaining the exact dimensions required for a seamless fit. The silver‑finished exterior not only resists corrosion but also matches the factory aesthetic of the original part. With a manufacturer part number of 5222193, this hub seal aligns with the specifications set by KING AUTOPARTS, ensuring that every dimension from the 5 × 5 × 1 inch package to the 3.2‑ounce weight meets the rigorous standards of off‑road equipment.
Designed for direct replacement, the seal eliminates the need for additional adapters or custom machining, allowing technicians and DIY owners to swap the old component with minimal downtime. The internal geometry is calibrated to preserve the original hydraulic pressure within the strut, which helps maintain ride comfort and handling precision even after extensive use on rough trails. By preventing water, dust, and mud from infiltrating the strut housing, the seal extends the service life of surrounding bearings and bushings, reducing the frequency of costly maintenance cycles. Its steel composition also offers superior tensile strength compared with polymer alternatives, delivering consistent performance across a wide temperature range from sub‑zero winter mornings to scorching summer afternoons.
The product is specifically matched to the 1989‑2009 Big Boss Sportsman series, a popular line of recreational off‑road machines that demand reliable suspension components. Compatibility charts from the manufacturer confirm that the seal fits model numbers 5222193 and the equivalent KING part number KINGOT001724, making it a versatile choice for owners who may have sourced parts from different suppliers. The fitment type is listed as a direct replacement, meaning the seal occupies the same mounting points and dimensions as the OEM part, eliminating the risk of misalignment. This level of interchangeability is especially valuable for fleet operators who need to keep multiple vehicles operational with a single inventory item.
Installation of the telfair seal is straightforward and can be completed with common hand tools in under thirty minutes. The process begins by removing the existing strut hub, cleaning the mating surfaces, and inspecting the surrounding components for wear. The new seal slides into place, guided by the pre‑drilled holes that align perfectly with the factory bolt pattern. Once seated, the strut assembly is re‑mounted, and torque specifications are applied to ensure a secure fit without over‑compressing the seal material. This user‑friendly approach reduces labor costs and minimizes vehicle downtime, which is critical for both recreational riders and professional service shops.
Beyond its primary sealing function, the component contributes to overall vehicle stability by maintaining consistent hydraulic pressure throughout the suspension cycle. When the seal performs as intended, the strut delivers predictable rebound and compression characteristics, which translates into smoother handling on uneven terrain and improved rider confidence. The steel construction also resists deformation under heavy loads, making it suitable for high‑performance applications such as racing, hill climbing, and heavy‑duty work where the suspension is subjected to frequent impacts. In addition, the silver finish helps dissipate heat generated by friction, further protecting the strut internals from premature wear.

Each telfair hub seal undergoes rigorous testing before leaving the factory, including pressure endurance, corrosion resistance, and dimensional accuracy checks. Samples are subjected to cyclic loading cycles that simulate thousands of miles of off‑road operation, verifying that the seal maintains its integrity under repeated compression and expansion. The quality assurance team records all test results, and any unit that falls outside the tight tolerance bands is rejected. This systematic approach guarantees that every seal delivered to customers meets the same high standards of performance and reliability.
The steel alloy used in the hub seal is formulated to resist both rust and wear, even when exposed to salty road treatments or coastal environments. Its surface treatment includes a phosphate coating that further inhibits corrosion while providing a low‑friction interface with the strut housing. This dual‑protective system ensures that the seal continues to function effectively after prolonged exposure to moisture, sand, and chemical de‑icing agents. As a result, owners experience fewer unexpected failures and enjoy a longer service interval between maintenance checks.
