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!
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.
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!!!

The Harley-Davidson oil pressure gauge! Tough, beautiful & accurate. This Stainless bodied 1 1/2" liquid filled oil pressure gauge is awesome!
This is my TC88 over the pond here in the UK, with an ERT SP-TC super pump kit fitted. Even after upgrading to the newest spec oil pump, cam carrier and hydraulic cam tensioner set up the ERT pump kit still improved and stabilized the oil pressures and I get 10-12psi on tick over. A wicked low cost awesome upgrade for any Harley.
Cheers ERT 👏🏻👍🏻👊🏻I
The springs arrived today and all I can say is OMG! Before I changed the spring I had 4 lbs. of pressure at idle with a cold engine and 18 lbs. at 2500 rpm. When the engine warmed up I lost all pressure at idle with the red warning light on and the gauge showing 0 lbs and got 15 lbs at 55 mph. The engine also rattled and ticked at idle badly. I installed the blue spring and took it for a drive. I now have 12 lbs.at idle and 35 lbs at 55 mph or faster. I am amazed! This is for sure the best thing I've bought for my bike yet and I'll be telling any and everyone who'll listen about what your product did for my Harley!
I installed the PJ-2 Pro-Just on my Evo custom. It works like a dream. I have all the oil pressure I need now. It is a pleasure to finally buy something for a Harley that works. Thanks a lot for your help. I will be telling all the Harley guys that I know about your stuff!
The unit is great! And with the aid of the oil pressure gauge, I have brought up the oil pressure to the correct levels using the PJ-2. I can now ride in peace, knowing that the most vital part of my engine( most vital part of any engine, OIL ) is being fed to all the necessary moving parts. Thanx again for sending it.
