Product Details

The COMP Cams 1452-16 Magnum Roller Rocker Arm Set delivers precision valvetrain performance for Pontiac V8 engines from 265 to 455 cubic inches. Engineered with a 1.65:1 rocker ratio, this complete set provides increased valve lift compared to stock rockers, improving airflow and power potential throughout the RPM range.

Key Features:

  • 1.65:1 rocker ratio for enhanced valve lift and performance
  • Roller fulcrum design reduces friction and wear for extended durability
  • Precision needle bearing rollers ensure smooth operation and minimal side loading
  • CNC-machined from high-strength aluminum alloy for accurate geometry
  • Designed for 7/16" rocker studs (standard Pontiac configuration)
  • Compatible with Pontiac V8 engines 265-455 cubic inches
  • Complete set includes rocker arms for all cylinders

These Magnum Roller rocker arms are ideal for street performance and mild racing applications where reduced friction and improved valve control are essential. The roller fulcrum design minimizes friction compared to traditional stamped rockers while maintaining durability and precise valve actuation. Proper installation requires 7/16" rocker studs and may require valve length adjustment to achieve correct preload or lash settings.

Easy to use website. Thanks

Great price, exactly what I needed. I will definitely return to Autoplicity for future autoparts orders! Thanks!

My son lives about 1500 miles from me. He had asked me to get him an Industries SuperFlow Hi-Volume Air Compressor for Christmas. <br>With a couple of click on my computer, the compressor was ordered to be shipped to him and was paid for. He had the exact compressor he requested within five days.(and that included the weekend)<br>One word sums up my experience---EASY

Wanted to buy my parts on another audtion site but found the price much better on Autoplicity, and the service seems friendly.

Very quick service and lowest price.
