Got two of these to replace the rear cooler struts on my Chaparral 256SSI. Perfect replacement.

Attwood Gas Springs are barely doing the job
by John from Fort Mill, South Carolina on March 05, 2016
I installed the new gas springs, just two months ago, and they are not working as well as I had hoped. I have to lift the cover all the way up by hand and it sinks down roughly 2 inches, when I let go. If didn't know any better, I would think that I had installed them 8 years ago because the previous set that I installed had lasted roughly 10 years. It feels like I will need to purchase new springs in the coming year. I do not know if that is typical for this brand.
