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.

Very comfortable. I like the moveable armrests and lumbar support.

As someone who spends a lot of time sitting and designing, I can't recommend this company enough to anyone looking for a new chair. My old cheap chair was wrecking my back, even when I tried to maintain good posture. I ended up sitting in awkward positions just to feel comfortable. I never realized how much a firmer chair could make a difference. A friend recommended this brand, and after using my chair for over a year now, I can't imagine going back.
