Product Details

The COMP Cams Ultra Pro Magnum Rocker Arm Set delivers professional-grade valve train performance for Chevrolet big block 396-454 engines equipped with 7/16" rocker studs. Featuring a precision-engineered 1.7:1 rocker ratio, this set increases valve lift and duration compared to stock 1.5 ratio rockers, maximizing airflow for improved horsepower and torque throughout the RPM range.

Key Features:

  • 1.7:1 rocker ratio for increased valve lift and enhanced engine performance
  • Ultra Pro Magnum design with full roller construction for reduced friction and wear
  • Precision needle bearings at fulcrum and valve tip contact points
  • CNC-machined from high-strength aluminum alloy for durability and light weight
  • Self-aligning roller tip maintains optimal valve stem contact throughout lift cycle
  • Compatible with 7/16" rocker studs on Chevrolet 396, 402, 427, and 454 big block engines
  • Complete 16-piece set includes all rockers needed for V8 application

COMP Cams Ultra Pro Magnum rockers are designed for street performance and racing applications where durability and precision are critical. The full roller design minimizes friction losses while the lightweight aluminum construction reduces valvetrain mass for improved high-RPM stability. Each rocker arm is manufactured to strict tolerances ensuring consistent geometry and reliable operation under demanding conditions.

Fast and Simple!

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 experience, good price, item arrived within 4 days of purchase, would do business with again in future !

Easy order placement, fast shipment
