Ratio Rockers for 25 & 36HP

Description

Upgrading to ratio rockers is a “tried and true” method of increasing engine power without having to rebuild your engine. They are perfectly suited to mild and stock cams.

If you are installing a speedwell supercharger these rockers are a great combination.

Modification to the valve cover are recommended or simply install the speedwell covers that cater for the extra clearance required.

Made of 4/40 cast steel, heat treated and nitrated, 30,000′ extra coating.

Sold individually.

Easy to install.
