Coatings:

The top coating is a high temperature thermal barrier coating(ceramic).

The skirt coating is teflon and helps prevent scuffing and galling.

Notes:

We recommend that all piston kits be installed by a competent professional.

Small end rod bore should be honed out to .907". Any competent machine shop can do this for you. Stock size is ~.906"

These are special order and may take up to 2 weeks.
