One size fits all, I think.
Seems like a universal fitment. Worked perfectly for me. Measure your old gas cylinder and ensure its the same height. I removed the black case because my chair had a different design however the silver part was standard size and fits well. There's small parts inside the black cylinder so be careful not to loose anything

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!

Fits well, make sure to measure the travel of old one as majority on here were actually shorter. Need hammer/mallet and a pipe wrench to remove old one. Simply mallet hit bottom to loosen from cylinder and years of sitting in chair, top chamber pipe wrench needed to spin about to loosen from chair. Then simply remove the new cap on the new cylinder and place in the feet and then top chair and sit on chair and move up and down a few times and then it’s like new

I can't say enough about how incredible this product is. I bought a very expensive showroom demo office chair for $100. I then realized that it is possible to use this product to revive the chair to 'like new'! I suggest you don't throw out your beloved office chair and just put in a new lift. It takes some elbow grease getting the old one out, but you'll feel accomplished and pleased with this product. Give your chair some surgery and don't kick it to the curb😿

Bought it an year ago, still working fine. Slightly expensive than from local vendors but it shows in quality.
