I have a 2019 Z21. The gas spring in my port side rod locker popped off and then the piston would no longer close. Meaning like it seized and I could no longer get the piston to slide in. I contacted Pro's Choice where I bought the boat and they sent me a new one. Well when I received the one they sent it would not close either. So I sent it back and they sent another. Guess what same thing the new one will not close. Tried a third time and same result. I am talking all my weight on top of it and it will not budge. Very frustrating. So I contacted Signature to see why this would be happening. I gave them the model number and they said the last number is the pounds of pressure which is 120 and that you would not be able to close that by hand even with all your weight on top of it. But it did work at one time so that doesn't make much sense. Checked my other rod locker and it has the same model number. So I am stumped. 120 pounds of pressure does seem very high to me. I thought they are usually about 40 or 50. Can someone check their rod locker and check the serial number preferably on a newer same model boat? Anyone else have this happen? Not sure what to do next. Thanks
