What is the primary benefit of the Ultra Pro Magnum design?

The Ultra Pro Magnum design uses 8650 chromemoly material and an arched, web-like structure to provide increased strength and rigidity. This construction also helps reduce the moment of inertia for better dynamic balance and overall engine performance.

Can these rocker arms be used with aftermarket valve springs?

Yes, these rocker arms feature optimized retainer and valve spring clearances. This allows for use with most common diameter springs, retainers, and +.050" locks without clearance or fitment issues.

What kind of warranty comes with these rocker arms?

COMP Cams offers a lifetime warranty on the rocker bodies against breakage. This warranty reflects the well-built nature and durability of the product.
