Product Details
Highlights
- New skirt coating technology is applied to the entire thickness of the piston-to-wall clearance for a zero install clearance; coating then abrades in on start-up to hone for the perfect fit per cylinder.
- Hard anodized top ring groove eliminates micro welding of the ring to the groove; this maintains a flat and smooth surface for the best ring seal and top ring groove.
- Skirt coating eliminates piston rock for the best possible ring seal with no piston slap noise.
- Hard anodized crown to aid in heat deflection and to reduce corrosion from alcohol fuels.
- Includes pistons, rings, pins and clips.
- Made in the USA.
