## Questions & Answers

**Q: No instructions...do I just jam it in, as it comes out of the box?**
A: if you have the old one out it should just be a matter of sliding it in where it needs to go reversing the process you did removing the old one and you probably don't want to jam it in. I had issues with mine as the old one didn't want to come out of the bracket on the bottom of the chair

**Q: Will this fit in a Razer Iskur chair?**
A: You need to check the measurements that they say. Diameter of the cylinder in the base, and the length of the shaft. I bought the long one it fit but the chair now sits a little higher when lowered and a lot higher when extended. Check the bottom Diameter in the base/wheels

**Q: I have a emerge vortex game chair (p/n 58293), will this cylinder fit?**
A: It would have fit my gaming chair but my old cylinder would not come out. I used everything but a torch to get it out. If you have one of the cheap Amazon chairs you might want to look at that first. I changed one in my drafting chair with no problems?

**Q: What is the difference between the two sizes? How do I know which one I need?**
A: One size (2.5) provides 2.5" of lift height, while the other (5.5) provides 5.5" of height variance. Which one you'll need depends entirely on how high you'd like/need the chair to be when you sit on it and how much you'd like that height to be adjustable when you work the hydraulics.

## Customer Reviews

### ⭐⭐⭐⭐⭐ De alta calidad
*by  on Reviewed in Mexico 4 January 2026*

Sin duda es el mejor cilindro de gas que he comprado, tenia uno que venia con mi silla gamer y que se descompuso (deja de subir el cilindro y se bajaba solo) Y compré este en su lugar. Antes que nada es mucho mas alto que los estándares y el recorrido que hace el cilindro al extenderse te da una altura mayor que a la de cualquier silla. Hasta ahora me ha servido y aguantada. Es muy resistente y si soporta el peso que dice. Por lo menos hasta donde yo se cerca de unos 150 kilogramos. Sin duda lo recomiendo y lo volvería a comprar. Además vienen de regalo unos guantes blancos de trabajo. Qué mas puedes pedir.

### ⭐⭐⭐⭐⭐ Deserves a medal for holding up the obese.
*by  on Reviewed in Australia 30 December 2024*

Give it ever medal known to man kind for being able to hold up a chair under an obese person.No seriously, DO IT.

### ⭐⭐⭐⭐⭐ Heavy-Duty and Reliable — Just Measure First
*by  on Reviewed in the United States 24 June 2025*

This replacement cylinder is a beast—strong, sturdy, and a great value for the price. It was easy to install and instantly made my chair feel more solid and secure. The product claims to hold up to 1000 pounds, and it really does feel that strong. No wobble, no slow sinking over time like my old one. My wife comes into my office and i'm not worried to have her hop onto my lap.That said, I made the mistake of not measuring beforehand. I was using this on a Lazyboy executive chair, and the new lift was taller than expected. Now my knees bump into the underside of the desk, which was on me for not double-checking specs. I’ve since ordered a shorter one, but I’m saving this for another chair because the quality is excellent.If you need a tall, heavy-duty gas lift and have the space for it, this is a solid choice. Just be sure to measure your setup first!
