Harley Twin Cam Oil

This Harley Twin Cam Oil Pressure relief valve spring kit from E.R.T. Products is designed to increase oil pressure on all 1999 and up Twin Cam engines. Increase your Harley Twin Cam Oil Pressure and performance by replacing the stock oil pressure relief spring ( Harley # 26210-99 ) in the oil pressure relief bore, (Twin Cam pop off valve) in the cam support plate.

By using the SP-TC, your Twin Cam performance is increased, the engine is quieter and oil temp. is dropped by an average of 20 degrees. A simple solution that is guaranteed to work!!!!
