Product Details

The COMP Cams 1833-16 Ultra Pro Magnum XD roller rocker arm set delivers professional-grade performance for Ford small block engines including 289, 302, and 351 Windsor models. Featuring a 1.7:1 rocker ratio, this complete set increases valve lift beyond stock specifications for improved airflow and enhanced engine performance.

Key Features:

  • 1.7:1 rocker ratio for increased valve lift and performance
  • Ultra Pro Magnum XD construction with roller fulcrum for reduced friction
  • Precision CNC-machined aluminum body for strength and light weight
  • Needle bearing trunnion design for durability and reliability
  • Designed for Ford small block 289, 302, and 351W engines with 3/8" rocker studs
  • Complete 16-piece set for 8-cylinder applications
  • Self-aligning roller tip reduces valve guide wear
  • Compatible with aftermarket roller camshafts and performance valve springs

The Ultra Pro Magnum XD series represents COMP Cams' premium rocker arm technology, combining lightweight aluminum construction with heavy-duty needle bearing components. These rocker arms are ideal for street performance, street/strip, and racing applications where reliability and consistent performance are critical. The roller fulcrum design reduces friction compared to traditional stamped steel rockers, improving efficiency and reducing valvetrain wear.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.
