The original Ultra-Gold Aluminum Rockers changed the way racing and high performance street engine builders approached valve train design. Now, COMP Cams is revolutionizing valve train performance again with the next generation of Ultra-Gold ARC Series Aluminum Rocker Arms, featuring an Arced, Recessed, Contoured design. Using cutting edge design techniques and manufacturing processes, Ultra-Gold ARC Rockers increase engine power, enhance valve train stability and improve oiling while fitting under stock valve covers.

Ultra-Gold ARC Rockers feature a new extrusion based on improvements developed through FEA analysis, resulting in an even stronger, stiffer body without compromising mass. A new arced channel and contoured top, similar to a bridge design, give the rockers the best strength-to-weight ratio possible. The body has additional CNC contouring to improve clearances for valve covers and springs. Manufactured entirely in the U.S.A., all Ultra-Gold ARC Series Aluminum Rocker Arms feature a spring oiler channel through the body for improved lubrication. Trunnion retaining clips have been replaced with an ultra durable spiral lock type clip, similar to what holds a piston pin in place. Stress relieving radii have also been added to areas of the body, trunnion and pushrod seat insert. Even the included locking nuts have been revised to increase surface area to better maintain lash and eliminate wear.

    Key Features:
  • Next gen Ultra-Gold Rockers increase engine power, enhance valve train stability & improve oiling while fitting under stock valve covers
  • New extrusion based on improvements developed through FEA analysis, resulting in an even stronger, stiffer body without compromising mass
  • Arced channel & contoured top give the rockers the best strength to weight ratio possible
  • Exclusive spiral lock type clips replace retaining clips
  • Proven to withstand extremely aggressive spring pressure & valve lift
  • Lifetime Guarantee
  • Made In The USA

Important notice.

If you’ve read our warning on engine builders using low grade no-name rods and cranks, a very similar situation exists in the roller rocker market. We do not use or sell off-shore, (no-name) roller rockers, period. They have proven to be faulty in many ways. The center trunnions are not polished, nor is the center of the roller tip true to size or polished. Metal fragments are often left inside the trunnion housing and will cause destruction of the needle bearings. The aluminum alloys used are never aircraft aluminum alloys as are used in all USA made roller rockers. They often mention the alloy as being 6061, and that is a very soft form of aluminum. The 6061 alloy used on these will assure rocker-flex on any higher than stock spring pressures, and this will affect performance. The pins and keepers that hold the parts together are often of poor quality and improperly installed. The front roller will usually scoot along the valve tip, as it can't roll properly due to rough internal surfaces.

We have honestly seen valve tips that were scalloped out due to the front roller dragging across them. This will cause the valves to side-load against the valve guides in the heads and surely cause damage to them if run like this for very long.

We have scrutinized these products in the past and found all of the above problems, and I can tell you there are most likely many more. We would not use them in an engine under any circumstances. You will also see many of these rockers made from stainless on the market. They use a very low grade stainless that actually has a near non-existent amount of nickel in them, but that's not the real problem with them, as stainless steel has no advantage over high grade heat treated steel when it comes to a roller rocker. The lack of hardness of the rocker body is the real problem. The problems with these stainless rockers are the same as mentioned above. These are the roller rockers you see on the market for around $119 and up to $169 for the so called stainless ones. They are pure junk, in our honest opinion. They could possibly be used on a budget back yard stock build up that has a very low spring pressure, with a cam that has very low lift, but then you would be better off with the stock stamped rockers on such a build.

We have heard of many engines using these rockers that came apart and spilled needle bearings into the engine, only to end up in the oil pump. It seems like some engine builders do not care how long the parts in your engine last, or they simply don't know this. I can tell you for sure that using such low grade, "no-name" roller rockers is asking for trouble.

We use Comp Gold Arc, Scorpion, and Comp Ultra Pro Magnum rockers in all of our engines. The difference in these compared to the low grade no-name rockers on the market is huge. Do a Google search on this subject and you will know then what we’re talking about.
