Product Details

The COMP Cams 1604-16 Ultra Pro Magnum rocker arm set delivers professional-grade valvetrain performance for Small Block Chevrolet engines. Engineered with a 1.52:1 rocker ratio, this set provides increased valve lift compared to stock 1.5:1 rockers, improving airflow and power potential without requiring camshaft changes.

Key Features:

  • 1.52:1 rocker ratio for enhanced valve lift and performance
  • Designed for SBC engines with 7/16" rocker studs
  • Ultra Pro Magnum series construction for durability and precision
  • Roller tip design reduces friction and valve guide wear
  • Includes 16 rocker arms for complete V8 valvetrain setup
  • Direct replacement for stock stamped steel rockers

These rocker arms are ideal for performance street builds and mild racing applications where increased lift is desired. The roller tip design ensures smooth operation across the valve stem, reducing friction and extending component life. Perfect for enthusiasts looking to maximize their camshaft's potential with a simple bolt-on upgrade.

Great price and easy checkout.

I was very impressed by Autoplicity's customer service and excellent pricing on brand name products. Also, they provided lightning fast shipping even as the holiday weekend approached.<br>As much as I want to see everyone in this world to "live long and prosper," I was especially pleased to deal with a company that did not export their customer service to another country. <br>I look forward to doing business again with Autoplicity.

Item shipped 5 days after order was placed. Worth the wait for the great price however. Order Number: 18722

I was shopping for a bed cover for my truck and found that autoplicity had the lowest price when I was ready to buy. After I placed the order, I got an email notifying me that my order was shipped and got a tracking number. Seamless transaction so far. Very happy.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere
