Stihl 021 Chainsaw Parts


The Stihl 021 is another very popular Stihl chainsaw, currently branded as the MS210 – both models are nearly identical, simply the name was changed. Slightly lighter then it’s big brothers, the Stihl 026 and Stihl 024 models, the Stihl 021 is a great choice for lighter work such as trimming trees, thinning bushes, or cutting up firewood – the perfect saw for those dealing with small trees and doing mostly trimming, but wanting something more substantial than a hedge trimmer or shears.


At HL Supply, you’ll find a full line of Stihl 021parts to help you repair and refurbish your saw. From the Stihl 021 carburetor to replacement bars and ignition coils, we offer almost every part for the Stihl 021, all guaranteed to meet or exceed OEM specifications.


Repair your saw today with the leader in aftermarket Stihl parts and components – browse our products below and get the Stihl 021 chainsaw parts you need to slice through the competition!
