Hub Seal GM Metric Ultra Low Drag L/W Alum

The Hub Seal GM Metric Ultra Low Drag L/W Alum is designed for high-performance GM vehicles, focusing on reducing parasitic drag and rotational mass to enhance fuel economy and power delivery. This metric-sized seal is a direct replacement for OEM units in modern GM drivetrains, making it essential for builders and enthusiasts looking to optimize engine efficiency or prepare vehicles for track use.

Constructed from aluminum, this hub seal minimizes inertial losses while maintaining the necessary sealing geometry for rear differential or transmission applications. Its ultra-low-drag design effectively reduces friction at the seal interface, which is crucial in differentials where even minor drag reduction can lead to significant horsepower recovery and cooler fluid temperatures under load.

Ideal for vehicles where weight is a critical factor, this seal weighs just 0.07 pounds, making it suitable for everything from bracket-racing builds to road-course competition cars. Mechanics and engine builders upgrading differentials and transmissions will find this product particularly beneficial, especially in GM LS and LT applications where OEM seals often fail under high-rpm or high-load conditions.
