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.

The chair is very nice and is height adjustable for complete comfort. The armrests are also adjustable to keep them at the right height for the work table. Assembly was very easy following the instructions and it was assembled in 20 minutes.

This chair is is quite nice. It feels very solid compared to the cheaper chairs I've tried, and I don't feel like it's straining if I lean backwards.
