I researched a lot of chairs and saw many YouTube videos where it's suggested to buy a good office chair but I suggest the opposite. This is a superior chair in my opinion.

I have a Racing Model chair from 2020. The Drifting lift cylinder was the replacement part I was told I needed. It works great, and following a few steps, it was easy to install. However, I do want to point out that it is a good bit taller than the original part, they do not swap out exactly.

Dxracer's has the best chair I have bought. It's worth the money, it's comfy and you sit for hours without any discomfort. Plus, It comes with a 3-year warranty, which you can extend for another 2 years, giving you a full 5 years of coverage! Customer service is responsive and genuinely helpful. Don't look further get yourself a dxracer.
