Tested and proven good! Northern Sledparts recommends ⭐⭐⭐⭐⭐
This kit contains products we have personally selected and tested. Therefore, we confidently recommend this product package! We have tested the kit's functionality in numerous 550F engines over the years. After years of testing and examining many seized 550F snowmobile engines, we can conclude that there is always a clear reason for seizing. Therefore, we recommend checking the snowmobile's fuel supply and any possible intake leaks before installing a new piston kit!
