Finally....roller rockers for the 4L enthusiasts!
Our roller rockers are available in bolt-on/adjustable, or for ultimate racing with screw in studs & proper guide plates for the application.
What makes these roller rockers unique, is the exclusive designed lifters. The lifters are the better choice, to keep the rockers properly lubricated by channeling the oil through the push rod, to the rockers.
Your original rockers are 1.5:1 ratio, on top of not being a roller rocker. By installing 1.8:1 roller rockers you will gaining over 0.080 lift, at the valve, while not changing the duration at all, which will increase the air flow ratio coming into the engine, as much as a cam would do, but without the added expensive of upgrading your camshaft, upgrading your engine management system, and adding additional and costly shop rates, as many can install these themselves.
You can expect 25 hp and 35 lbs torque gains (Flywheel)
