About Allstar Performance

Allstar Performance is America's leading circle-track racing parts manufacturer. From aluminum panels and chassis components to brake hardware, steering boxes, and oval-track shock packages — every Allstar product is born from sprint car and modified racing experience.

Optimize Crankcase Pressure with Lifter Valley Vents

Manage internal crankcase pressure effectively with the Allstar Performance Lifter Valley Vents. Designed specifically for Small Block Chevy engines, these 1/4in NPT vents help equalize pressure between the lifter valley and the crankcase, reducing windage and improving oil drainage. This set of eight clear-anodized aluminum vents offers both functional performance and a clean, professional look for your engine bay.

Technical Specifications

  • Material: Lightweight, high-quality aluminum with a clear anodized finish.
  • Size: 1/4 inch NPT threads for secure mounting in the lifter valley.
  • Design: Hex head for easy installation using standard tools.
  • Quantity: Sold as a complete set of 8, perfect for a full engine build.

Proper crankcase ventilation is key to unlocking horsepower and extending engine life. By allowing air and oil to move freely, these vents prevent pressure buildup that can cause oil leaks and power loss. Upgrade your SBC with these precision-engineered components to ensure your engine runs at its peak. Find these vents and other premium engine accessories at GGCRACING.
