Product Details

The COMP Cams Ultra Pro Magnum rocker arm set delivers precision performance for small block Chevrolet engines. Engineered with a 1.6:1 rocker ratio, this set provides increased valve lift compared to stock 1.5 ratio rockers, enhancing airflow and performance potential without requiring camshaft changes.

Key Features:

  • 1.6:1 rocker ratio for increased valve lift and improved engine breathing
  • Designed for small block Chevy engines with 7/16" rocker studs
  • Ultra Pro Magnum construction with roller trunnion bearings for reduced friction
  • Precision CNC-machined aluminum body for strength and weight savings
  • Self-aligning design compensates for stud and valve tip variations
  • Includes poly locks for secure installation and valve lash adjustment
  • Compatible with both hydraulic and solid lifter camshafts

This rocker arm set is a popular upgrade for performance street engines, offering durability and precise valve train control. The roller trunnion design minimizes friction and wear while the aluminum construction reduces reciprocating weight for higher RPM capability. Ideal for enthusiasts looking to extract more power from their small block Chevy without major camshaft modifications.

Best pricing on the web for Dorman product line!

good

Quick delivery, great product

Very pleased with timely delivery and product.

No problemo

I'm very happy with it.

Best price I found anywhere!

Very simple checkout

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.

Great price on the gas jugs

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

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.
