COMP Cams Ultra Pro Magnum Rocker Arms
Utilizing years of valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (dyno and Spintron), COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level. The most noticeable advancement centers around their nearly unbreakable investment cast 8650 chromoly body. The arched, web-like design delivers a nearly 29 percent increase in strength and rigidity, while reducing the moment of inertia and optimizing the dynamic balance. The resulting rockers maximize lift and valvetrain control at high rpm. The increased retainer and valve spring clearances of the new design enable the use of large-diameter valve springs, retainers, and locks, without clearance or fitment issues. The new black oxide exterior finish offers a distinctive appearance, along with long-term corrosion resistance. The COMP Cams Ultra Pro Magnum rocker arms feature an oversized trunnion and precision-sorted needle bearings designed for use with high-load valve springs. These unique rockers also feature hardened roller tips for reduced friction and elimination of the valve stem "side loading" that causes premature valve guide wear. The COMP Cams Ultra Pro Magnum rocker arms feature a fully rebuildable design, which means that they very well may be the last rocker arms that you ever have to purchase.

When in a pinch, even Monaco couldn’t tell the difference.
Size: XX-Large, Color: Navy
Here’s the revised review with the updated final paragraph: --- **When in a pinch, even Monaco couldn’t tell the difference** There I was, stranded in the Swiss Alps, of all places, when an urgent call came through—a last-minute invite to a charity gala in Monaco. You can imagine my predicament. No tuxedo, no time to fly back to Dutchess County to retrieve the one I had custom-tailored in Sardinia by Fabrizio, the island’s finest (and only) tailor. Fabrizio’s tuxedo, you see, wasn’t just any suit. I had it made after a rather *unique* incident involving a chess tournament, a peculiar art heist, and the world’s finest pecorino cheese. But I digress. With no time to return to Dutchess County—or even Sardinia—there I was, frantically searching for something that wouldn’t make me look like an underdressed disaster among the crème de la crème. Amazon to the rescue. I stumbled upon this navy blue tuxedo with a black shawl collar and, in a state of mild desperation, ordered it around midnight. It arrived before I even woke up the next morning. Amazon’s overnight delivery, an absolute lifesaver. I put it on, and, to my surprise, the fit was near perfection—almost as if Fabrizio himself had secretly slipped his measurements to the manufacturer. The deep navy color was striking, and the black shawl collar gave just the right amount of contrast. It looked like a tuxedo far more expensive than the one I’d ordered in a slight state of panic. At the event, the tuxedo didn’t just blend in—it stood out. More than a few people took notice, including a former diplomat who, with raised eyebrows, asked if I’d had it custom-made in Milan. I simply smiled and let the mystery linger. The tux held its own through hours of mingling, dancing, and even a few strategic maneuvers to avoid the advances of a rather persistent heiress. And by the end of the night? Not a wrinkle to be found. Now, about the fit—be warned. It's tight. Very tight. If you decide to give this tux a try, order two or even three sizes up. And unless you have time to see a tailor, the trousers will almost certainly need hemming. In a real pinch, fabric tape will do the trick. But once you’ve got the sizing sorted, it’s all smooth sailing from there.

Tricky Fit
Size: 3X-Large, Color: Black
First order returned - pants fit, jacket & vest too small. Reordered a size up - pants too big, jacket & vest fit. The pants had to be hem and waistband taken in. And still need suspenders. My advice, give yourself enough time for alterations.

Good quality
Size: 3X-Large, Color: Black
Loved the quality for the price. Fit is more for a size under what is listed. The pants are hip huggers not waist high.
