Higher Quality Material

Higher silicon content means its expands less. Less expansion, lasts longer, lubricates better and runs cooler

Better-than-OEM Machining

Higher tolerances, more uniform, has a .003" taper from skirt to crown allowing it be be run harder at hotter temps. Saw modders, modders hot saw builders take note because you can push the limits of your saw builds more, with reduced scuffing risk.

Skirt Coating

The skirt coating is an ultra slick dry molybdenum disulphide coating. This helps during break-in but even after the cosmetics of it wear down there remains an imbedded microscopic layer in the skirt surface. You may not see it after 100 hrs but its still in the skirt alloy and still doing its job, lowering friction and heat.

Piston Crown Anodizing 

The crown has anodized thermal barrier, similar to a ceramic thermal barrier coating. It significantly reduces combustion heat from saturating the piston. This reduces the piston-heat induced expansion (cooler motor) and keeps the combustion heat where it belongs for more thorough combustion. Thorough combustion = better power.

Using Ceramic Hybrid Bearings In Your Chainsaw

Oh, if you have spent the cash and time to put a hot piston in your saw, consider our ABEC 5 hybrid-ceramic bearings. We would not bother to sell them if we believed they did not make a real difference. These are insanely smooth and a massive upgrade over the stock, $25-a-set, full-chrome ABEC 3 bearings. Trust me on this, 372's love to kill bottom ends, and with a hot top end, well, you get the picture. They spin faster, are lighter, have much lower friction and last much longer.
