DUST CAP

This is a Spicer SPL90 series dust cap designed for a slip yoke or drive shaft assembly on heavy-duty trucks. It seals out dirt, moisture, and debris from the splined connection, preventing contamination that can cause premature wear or corrosion. Replacing a damaged or missing dust cap helps maintain proper lubrication and extend the life of your drive shaft. It is commonly replaced when the dust cap is lost, cracked, or during driveline rebuilds.
