Summit Racing™ Digital GM High Energy Modules with Rev Limiters

1.0 out of 5 stars 4 Customer Reviews

Summit Racing™ offers GM high-energy modules with rev limiters that enable you to adjust the rpm limit from 5,000 to 9,500 rpm. They are high performance modules built for HEI distributors, producing 50 percent higher coil drive currents than the stock module. This saturates the coil faster, delivering more spark energy at top speeds. Your benefits are increased horsepower and rpm range, plus improved starting. GM HEI modules replace all 4-pin modules used in HEI distributors with a vacuum advance canister. They can be used with factory or aftermarket HEI distributors.
