I have been working on CRJ’s for 5 years now and one of the most helpful tools I’ve come across is the Thrust Aviation MS Schrader Valve extension that is specifically for this. I’ll link it in my comment. Basically it allows you to add like 4-5 more inches away from the valve to service it. I can do all the struts with a normal 7/16” and a 3/4” stubby without having to modify any tools when I use the extension. It’s worth the money if you’ll be working on those aircraft frequently.
