Product Details

The COMP Cams 928-1 Race Sportsman dual valve spring is engineered for high-performance racing applications requiring precise valvetrain control. This premium dual spring design features a 1.550-inch outer diameter and is designed for a 1.880-inch installed height, providing reliable valve control at elevated RPM ranges.

Key Specifications:

  • Dual spring construction for enhanced valvetrain stability
  • 1.550-inch outer diameter
  • 1.880-inch installed height specification
  • Race Sportsman series design for performance applications
  • Sold individually (1 spring per package)

COMP Cams valve springs are manufactured to exacting tolerances using high-quality spring steel to resist valve float and maintain consistent pressure throughout the RPM range. The dual spring configuration helps prevent valve spring surge while providing the necessary seat pressure for aggressive camshaft profiles. Proper installed height and valve spring pressure should be verified during installation to ensure optimal performance and engine longevity.

Excellent prices

Hello, Good price, almost as low as Amazon, but Amazon shipped me a broken headlight switch :( twice! :( So for my order# 602429, please bubble wrap it really, really, really well please, and then I will be ordering more parts from Autoplicity. Thank you! Jeff

Great products. Great service.

very good so far

Website is well laid out and prices are excellent

product just as described, received in 3 days

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good price, fast delivery, just charge a little bit high on the shipping cost. Will refer friends to shop here.

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
