Product Details

The COMP Cams 1608-8 Ultra Pro Magnum rocker arm set is specifically engineered for Small Block Chevy engines equipped with Twisted Wedge cylinder heads. This complete rocker arm kit features a performance-oriented 1.6:1 rocker ratio that increases valve lift compared to stock 1.5 ratio rockers, helping to improve airflow and engine performance without requiring a more aggressive camshaft.

Key Features:

  • 1.6:1 rocker ratio for increased valve lift and improved performance
  • Ultra Pro Magnum design with needle bearing fulcrum for reduced friction and increased durability
  • Precision CNC-machined from premium materials for consistent geometry
  • Application-specific design for Small Block Chevy engines with Twisted Wedge heads
  • Complete set includes all necessary rocker arms for V8 application
  • Self-aligning design compensates for minor geometry variations
  • Reduced friction compared to stock stamped steel rockers for improved horsepower

These roller-tipped rocker arms feature a needle bearing fulcrum that reduces friction at the pivot point while providing exceptional durability under high-performance conditions. The precision manufacturing ensures proper valve train geometry and reliable operation throughout the RPM range. Ideal for street performance and mild racing applications where increased valve lift is desired without changing the camshaft.

First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

The ordering process was very simple and the prices could not be beat. The processing time to ship the order was a little longer than usual, but for the price savings, it was well worth it!

cheapest price on the web thanks for the great value, shipping was <br>a little slow but it was free and came with a tracking number<br><br>Thanks<br>

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Great customer service, item shipped quickly. Very satisfied.

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

I couldn't find these ARP studs anywhere else for this price! $20 less than ANYWHERE! Definitely coming back to shop at Autoplicity.

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
