Product Details

The COMP Cams GP959-KIT is a complete dual valve spring and retainer kit engineered for Briggs & Stratton performance and racing engines. Designed to accommodate camshaft lifts up to .380 inches, this kit provides the increased spring pressure and valve control necessary for high-performance builds where the stock single spring setup falls short.

Key Features:

  • Dual valve spring configuration for improved valve control at elevated RPM
  • Designed for .380" maximum valve lift compatibility
  • Includes matched retainers for proper spring seat geometry and secure keeper engagement
  • Engineered specifically for Briggs & Stratton engine platforms commonly used in karting, racing, and small engine performance builds
  • Manufactured by COMP Cams to precise tolerances for consistent spring pressure and rate
  • Helps prevent valve float and improves throttle response at higher engine speeds

COMP Cams is a trusted name in valvetrain performance components. The GP959-KIT is an ideal upgrade for competitors and enthusiasts looking to maximize the potential of their Briggs-based powerplant with a reliable, race-proven valvetrain solution.

All around good experience. Easy ordering, quick delivery, and great price for quality product.

I had to contact autoplicity as the website had the wrong description of the item. The person that was able to assist was very knowledgeable and assured me that the description would be changed. That was last week and as of today, the description remains as is. However, and more importantly, I received the gauge quite quickly and it is the one I needed. So on that they did a great job!!!

Very simple and easy... Great prices

Wow the quick service and low prices at autoplicity helped me and made it easy to find which car parts retailer is the best!

Fast connection with Amazon

Great price, fast shipping, excellent customer service. I will definitely do business with them in the future.

Pretty simple and easy to use. Shipping is confusing as the selection wasn't reflected on the invoice and didn't update on my order. The product came to my house and said at warehouse on the tracking.
