Review on 💪 (2) 20 Inch 60 lbs Gas Prop Lift Springs for Rod Struts Heavy-Duty Tool Box Lid Top RV - Pair by Cedric Edwards

. There are some differences. They have 1/4" rods instead of Watkins' 5/16". The pressure cylinder (the black, thicker part) is also smaller in diameter than the original Watkins. Both these and the originals are 20 inches long and 60# tall. They cost about $25 a pair; Watkins - $75 each. I decided to try these and they worked great. They might not last as long as the originals, but considering the price difference, they're worth installing.
