Use these components to maximise performance and reliability. Roller rockers are designed to operate the valves with less resistance and more efficiency. The power increase with the use of these rockers is approximately an extra 10bhp.
The aluminium rockers are made with needle roller inserts and have solid spacers ready fitted; the end roller tips are made in high quality steel for long life. The roller rockers are also designed to give a higher lift ratio, 1.65:1 against the standard ratio of 1.5:1. The design is also specially strengthened against deflection at any time in the operating sequence.
This conversion must be only be used with full race valve springs and the corresponding valve caps. It goes without saying that uprated push rods are used with this conversion.
