Product Details

The COMP Cams 1418-12 Magnum Roller Rocker Arm Set delivers precision performance for 1988 and newer Chevrolet V6 and small block Chevy engines equipped with 3/8" rocker studs. These high-quality roller rocker arms feature a 1.6:1 rocker ratio, providing increased valve lift compared to stock 1.5 ratio rockers for improved airflow and performance.

Key Features:

  • 1.6:1 rocker ratio increases valve lift by approximately 7% over stock
  • Needle bearing roller tip design reduces friction and wear at the valve tip
  • Precision-manufactured steel construction for durability and consistent geometry
  • Full roller bearing trunnion for smooth operation and extended service life
  • Self-aligning design compensates for minor geometry variations
  • Fits 3/8" rocker studs commonly found on small block Chevy heads
  • Compatible with stock and aftermarket cylinder heads with correct stud spacing
  • Set includes 12 rocker arms for complete V6 engine coverage

COMP Cams Magnum Roller Rocker Arms are an excellent upgrade for street and street/strip engines, offering the performance benefits of increased lift and reduced friction without the complexity of a full shaft-mounted rocker system. The roller tip design significantly reduces side loading on valve stems, extending valve guide life while improving power and throttle response throughout the RPM range.

EXCELLENT PRICING, EXCELLENT ITEM, AS DESCRIBED, GOT IT VERY FAST, DEFINATLEY WILL DO BUSINESS AGAIN

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

My first order did not include all parts. I'm ordering a different part number now. The seller is giving me a discount due to this inconvenience. We will see how it goes.
