MASTERY MART 9 Inches to 13 Inches Gas Lift Cylinder for Most Office Chair, 4" Stroke, Heavy Duty 1000lbs, Office Chair Gas Lift Cylinder Replacement, Class 4 Pneumatic Piston (Not for 1KEA, Black)

Bought this to replace the piston in my aging Vertagear gaming chair. Perfect replacement. Gives the same lowest level with an extra 1inch/2.5cm of height. Easy to fit, well packaged and seems to work really well. Only time will tell on its longevity. TOP TIP: Be aware that there are varying low and height differences so be sure to measure your existing pistons lowest, highest, overall length and travel length. It's also a good idea to check the taper at the bottom of your existing pistons as not all pistons are equal in this area. This one sticks through the bottom quite a bit so if your wheel base is low to the ground it will probably hit the floor before the wheels. In that case go for one with less of a taper so not so much of the piston sticks out the bottom of your wheel base.

MASTERY MART 9 Inches to 13 Inches Gas Lift Cylinder for Most Office Chair, Fitted a Corsair T3 rush gaming chair which the cylinder failed. I believe the Corsair chair has had two replacements cylinders with the last one lasting around 6 months before failing spectacularly. This fitted the gaming chair perfectly and is a good replacement. I'm hoping this last far more than 6 months so will update the review if anything happens. Installing the cylinder was easy enough i couldn't salvage the base plate due to the damage so i also had to replace the tilt plate and base with the wheel. Overall This so far is good and fitted perfectly well, good value comparing to the original which in my opinion fails fairly quickly and the person isn't at all heavy.

really pleased with the ram , obviously cheaper than a new chair , the only problem so far was getting the old one off

Perfect fir for my chair and lift works perfectly. Once the old strut was out this was a really simple fit and feels well built. Nice Chrome outside which matches my chair perfectly.

Works and fit perfectly

Absolutely spot on. Delivery was very quick, it's a well made piece, excellent. Not much more I can say. BUT be prepared to have a nightmare getting your old one out. (obviously this is nothing to do with this, just a foreword to everyone replacing). I have found the best way is once you have the chair off, find a barrel, flip it upside down so the legs rest on the barrel. Then get a hammer and give it all you have. They are 'friction' connections (like a car wheel hub). Try not to lose you rag 👍

I bought this product as my gaming chair had broken and I was just about to replace the entire chair. I came across this item and it worked absolutely perfectly I've had saved me a fortune. Would absolutely recommend this

My girlfriend have 51 kg and this item has be broken after 2 tries

Es funcional, es lo que requeria

Great replacement cylinder! The size was spot-on, installation was straightforward, and it brought my chair right back to the height and stability it originally had. Smooth lift, solid feel, and no sinking issues at all. Exactly what I needed highly recommend if you’re repairing or upgrading an office chair.

Item arrived on time and as described. The fit is very well and it works very well as a replacement for the original hydraulic piston that had worn out.
