Easily to replace for right shock
I bought these by mistake 35Lbs was to strong for my tool box. I returned them and got the 10" 10lbs ones and works great. Great company easily fix my problem, Fit great , good price, instructions and mounting hardware included

Just what I needed
These worked great, and we're very easy to install. They appear to be of good quality and the pressure is evenly distributed. And the price was great

Fixed the saggy old gas struts in my safe
I bought these to replace the worn-out stays on my Sentry Safe, and they’ve made a huge difference. I was worried they might be too stiff or not fit the original mounting points, but they snapped right into place without any hassle. The 35lb tension feels just right—the lid stays open securely now without me having to worry about it slamming shut on my fingers, but it’s still easy enough to close. It’s a much cheaper alternative to buying "official" replacement parts from the manufacturer, and honestly, the quality feels just as good, if not better.

Love these
These struts work very nicely on my truck toolbox. They are easy to install and work great. I have needed these for quite sometime, so I have to get used to having them now. I love that now the lid to my box doesn’t come close to hitting the back of the cab anymore as well..

weak brackets for the spring load
The slotted ball stud brackets are not stainless steel and bent under the pressure of the 40lb gas springs. The springs themselves are working normally so far.
