Product Details

The COMP Cams Ultra Pro Magnum XD Roller Rocker Arms deliver professional-grade performance for high-performance Ford big block and Boss engines. This 8-piece rocker arm set features a 1.8:1 rocker ratio, providing increased valve lift for improved airflow and power output compared to stock rockers.

Key Features:

  • 1.8:1 rocker ratio for enhanced valve lift and performance
  • Precision roller tip design reduces friction and valve guide wear
  • Heavy-duty extruded aluminum body with steel reinforcement trunnions
  • Needle bearing fulcrum and roller tip for maximum durability
  • Designed for 7/16" rocker studs
  • Compatible with Ford Boss 302, 351 Cleveland, 429, and 460 engines
  • Self-aligning design accommodates varying valve stem heights
  • CNC-machined for precise tolerances and consistent geometry

The Ultra Pro Magnum XD series represents COMP Cams' premium rocker arm line, engineered for high-RPM racing applications and aggressive street/strip builds. The roller tip design minimizes side loading on valve stems while the needle bearing fulcrum provides smooth, friction-free operation. These rocker arms are ideal for performance enthusiasts seeking maximum reliability and power gains from their Ford powerplant.

This copany shipped my order promptly. I would do business with them again.

Quick process, best price

Fast& easy checkout, unfortunately no option for faster than ground shipping that I really need for this purchase. I will be vertu impressed if it gets sent out this morning & to me tomorrow

Fast and quick.

Great prices and simple Amazon account checkout.

A fluid interface coupled with an easy to manage mobile platform has made the shopping experience thus far pleasing. After receiving my package, in a timely fashion, I was very pleased!

Quick and easy and the best prices around the net thanks. Very Happy.

Autoplicity has great prices and customer service. Shipping is fairly fast too. Ordered product on Monday and it was shipped on Wednesday. Will make future purchases with this company.

Fast shipping, good customer service!

Fantastic site! Received exactly what I ordered in a very timely manner. Customer service is outstanding, will be doing business again!

Very nice service

Had to call technical service for a question. Hold time was very long but once connected the technician was friendly and helpful.

So far so good

Shopping was easy and being able to pay via Amazon is convenient. I do have to say autoplicity shipping emails and tracking webpage is behind. By the time they notified me that it shipped I had already received the products 2 days before. That's not a bad
