Hub Seal Baby Grand

The Hub Seal Baby Grand from WINTERS is a precision inner hub seal designed for high-performance automotive and racing applications. This compact component is essential for anyone running a dedicated race car, performance street machine, or custom-built drivetrain where wheel bearing integrity and axle seal performance directly impact safety and longevity. Whether you're building a circle-track racer, drag car, or street rod, this seal helps maintain critical protection against fluid loss and contamination at the wheel hub interface.

Manufactured for durability, the Hub Seal Baby Grand delivers reliable sealing geometry and material composition designed to withstand repeated thermal cycling and high-speed operation. Weighing just 0.09 lbs and with compact dimensions of 3.9 x 0.45 x 3.95 inches, this seal fits tight hub packages while maintaining the pressure retention and wear resistance required in motorsports environments. The precision fit ensures minimal runout and consistent contact against the hub bore, preventing grease migration and water intrusion that can accelerate bearing wear.

Mechanics and fabricators working on rear-end assembly, independent suspension builds, or modified axle housings will find this replacement seal beneficial. Proper installation requires ensuring hub cleanliness and correct seating depth to maximize service life—using a seal driver tool is recommended for optimal results.
