Tire Valve Stem Extension Adaptors for 2020 3500HD Sierra Dually


Recommended Posts

I ordered two Tire Valve Stem Extension Adaptors from Amazon and just returned from NAPA Auto Parts after looking at part no. 90330 (https://tinyurl.com/y5btdspp). While both products are long enough (7"-10" in length), neither will permanently attach to the exterior (not inner) ALCOA wheel on my dually.  Has anyone modified the rear inside tire valve to accommodate easier access? This is the part I received from Amazon:  https://tinyurl.com/yyj9kljf  Thanks all!

I owned duallies for 24 years, with both steel and aluminum wheels.  All I ever needed were regular valve cap extensions that could measure and fill air through the cap (like these:  https://www.amazon.com/AUTOHAUX-Extension-Extender-Adapter-Plastic/dp/B07V3QQ6SY/ref=sr_1_18?dchild=1&keywords=valve+cap+extension&qid=1601320430&sr=8-18 ) and a dual head gauge (https://www.amazon.com/Milton-S-927-Dual-Truck-Gauge/dp/B000COS0R4/ref=sr_1_7?dchild=1&keywords=dual+head+tire+pressure+gauge&qid=1601320576&sr=8-7 ).  Had no trouble measuring or filling the 4 rear tires with those.
