Hub Seal M/C 1978-88

The ALLSTAR PERFORMANCE Hub Seal M/C 1978-88 is an inner lip bearing seal engineered for front hub applications on GM A-Body and G-Body vehicles spanning the 1978–1988 model years. This critical sealing component prevents bearing contamination and lubricant loss, maintaining the integrity of your wheel bearing assembly under street and light-duty racing conditions.

Precision specifications make all the difference in bearing seal performance. This seal features a 2.566-inch outer diameter, 2-inch inner diameter, and 0.22-inch thickness—dimensions that match OEM hub cavities for a secure fit without modification. The dual-material construction combines rubber flex properties with steel reinforcement, allowing the lip to maintain contact pressure against the bearing race while resisting wear and heat cycling. Proper sealing prevents water ingress and grease migration, both critical to long-term bearing life.

This hub bearing seal is essential for any restorer, street rodder, or performance builder working with first-generation A-Body (Chevelle, Malibu) or G-Body (Regal, Grand Prix, Cutlass) platforms. Whether you're rebuilding original suspension geometry or upgrading to modern brake and wheel combinations, proper bearing sealing prevents the premature failure that results from contamination. ALLSTAR PERFORMANCE's focus on chassis components makes this seal a reliable choice for stock restorations and custom builds alike. Each seal is sold individually, allowing builders to purchase exactly what their project requires.
