I also have a 141" SW. The only 141" track currently available, as far I have found, is the one ply Back Country 1.75" track. I have had this track on my sled since new as the 2019 X-TX LE came from the factory with it. The Back Country on my sled has been excellent and amazingly durable. The only other track option is to install a 144 2.52" pitch track as there are a lot more options. To change from a 141 to a 144 you will need to install 2.52" drivers as the 141 uses 3.0" drivers. I have all the components and a 144" Ice Cobra 2 ply track needed to convert mine but I have hesitated to do it as the Back Country track has performed so well for my riding use.
