DOZYANTGas Lift Cylinder Replacement,Hydraulic Pneumatic Shock Piston Heavy Duty (450 lbs) Universal Size Fits Most Executive Office Chairs, Highest End Class 4

Worked perfectly, was worried I needed to buy a new chair, this was def a economical way to preserve this office chair a little longer. Removal of the old ram is tough, but a hammer and a punch and some anger I was able to get it knocked out without too much pain. Installation was about as easy as it could get.

Bought this for my home office chair when my last one developed a leak. Easy to replace the old one. New cylinder works VERY well with easy adjustments and strong--not sloppy-holds well. Saved alot of $$ by replacing the cylinder instead of the whole chair. Good quality.

When the gas lift on my office chair started giving out, I was on the brink of buying a whole new chair. That’s when I stumbled upon the DOZYANT Gas Lift Cylinder, and I decided to give it a shot. This decision turned out to be a game changer! The installation process was incredibly easy, and it fit my executive chair like a glove, thanks to its universal size design. It's evident that this cylinder is built to last, supporting up to 450 lbs with a seamless and smooth operation, making it feel like I've got a brand new chair. The hydraulic pneumatic shock piston operates flawlessly, providing the perfect amount of lift and stability. What impressed me the most is how it has transformed my seating experience at work, ensuring comfort throughout my long hours at the desk. This product is a lifesaver for anyone looking to fix their office chair without breaking the bank. The DOZYANT Gas Lift Cylinder is a high-quality, durable solution that I would highly recommend to anyone facing similar chair woes. It’s truly a top-notch product and the highest end of its class!

It is a good product, but MEASURE.I got for a Sealy Hensley. It was too long, resulting in the lowest position leaving my 6ft-2in frame with feet dangling 4 inches off the ground.Also, don't use a Pipe Wrench to remove the old one - use the extraction rings available on Amazon or bundled with another Cylinder product. The pip wrench stripped metal shard needles off the old cylinder, only to be picked up by bare feet.

These chair cylinders are nowhere near as easy to remove as some videos show. Usually they're wedged in there unbelievably tight, but there are ways to win the battle. I checked other online videos for removal techniques and soon afterwards, this part was a great replacement. It fit perfectly, drops right in, appears to be better built than the original and so far has held up very well despite my above average build. Definitely worth the price and a little effort! Highly recommended!

The gas lift cylinder arrived well-packaged and in perfect condition. It was easy to install and works perfectly so far. It’s sturdy and brought my office chair back to life. Really happy with how it turned out.

Worked perfectly in my Quantum 9000 office chair. I unclipped the old canister from my old chair, and removed it from the seat, and then just used the canister (not the exterior black housing that comes with this) in my chair. It fits perfectly, and works without problems. Since I'm using the housing from my chair, rather than the black housing this comes with, everything looks identical to how it did before.

It worked well and was easy to install.
