Quites your Lifters
Harley-Davidson has had excellent hydraulic lifters since the Evos! Problem is, you have to have oil pressure for them to operate properly. Great news, we at E.R.T. Products, Inc., have the solution for Harley oil pressure problems !! When your lifters are quite, they are working properly!
Cools your Engine
Would you like to lower your operating oil temperature without installing an oil cooler? Of course you would!! By using our products & having proper oil pressure, you will average a 20 degree F. drop in warm engine oil temperature.
Increases Horsepower
When your lifters are working properly, they follow the camshaft profile. This means that your valves open and shut in time and stay open for the length of time that the cam was designed for. Highly Accurate Lift and Duration! This will make a serious increase in performance.
