Product Details
If you're looking to get a little more performance out of your GM LS3 engine without changing the camshaft, these Ultra Pro Magnum rocker arms from COMP Cams are a solid option. They're designed to increase the rocker arm ratio and stiffness compared to your factory parts, which can lead to improved lift and better valve control. This is a popular upgrade for LS engines found in a wide range of vehicles, including the Chevrolet Camaro, Cadillac CTS, and GMC Sierra.
These rockers are made from 8650 chromemoly steel with a black oxide coating, giving them the strength to handle up to 850 lbs of spring pressure. The 1.8 ratio is a notable increase over stock, helping to open the valves further and for longer, all while fitting onto the pedestal mount style heads found on LS3, L99, and L76 engines. They come with the necessary bolt for installation, making it a straightforward swap for many LS applications.
