Are my shocks still good?

I have some adjustable 5100’s I took off my truck 4 years ago. They been sitting in my garage set on the middle setting. Do y’all think the shocks are still good? Does the shock fluid go bad from just sitting in there. The shocks have about 10k on them.

I just found a website that had some rear 5100’s in stock and bought them. Want install the fronts and rears next week but not sure if I should use the fronts or purchase some new ones whenever they become available.
What are your guys thoughts?

 

I’d totally throw them on. After all, they have a lifetime warranty, so if one leaks you can then get it replaced under that warranty.

 

I really want to get 6112’s but we all know how hard it is to find any in stock. Since I have these I’ll run them till I can get some 6112’s. Thanks for your input fellas.

 

They are fine man, throw them on and have some fun!

 

Yeah! I’m over thinking it.

 

I'd throw them on and send it!

 

Ok, I got another doozy for you guys lol What size tire would make me lose more HP, Torque, and mpg?? 295/70r18 Nitto G2 in stand load that weighs 50.5lbs
Or 275/70r18 Nitto G2 E load and weighs 53lbs this is my 3rd Tundra so I don’t care about mpg more so HP and Torque
