Description
Hamilton 103 Pound Valve Spring Set 98.5-18 Dodge Ram 5.9L / 6.7L CumminsStock 24v springs allow the intake valve to completely blow open at 50psi on the bench, but still start to open at 35psi. This is a major problem and it is intensified as RPM increases. With high drive pressures your engine might even be experiencing reversion, when the exhaust valve blows open on the intake stroke contaminating the intake charge. Get control of your valves with a set of Hamilton springs. Stock springs have 78 82lbs of pressure seat

Thing is absolutely garbage. Ball didn’t make it back once! Broke in half

Good toy for dogs
This is a great toy! I do wish the handle was a little longer because I do not have a lot of upper body strength due to health issues. I can still throw with this further than I can without the launcher so my dogs really love it and get excited any time I get this out!
