We can  do custom stroker or knife-edge crank designs.  We can provide templates for initial fitting and adjustment. Templates cost $100 and are a separate charge from the scraper pattern chosen.

We have included some representative pictures of the scrapers we make.  If you would like to see a picture of a particular scraper please ask -- we would be more than happy to send one through.

When available (please enquire) our zero-clearance Teflon® scrapers run an additional $130.00 to the cost of the standard steel scraper unless noted.

Remember, your vehicle may have an engine made by a different manufacturer so check both product lines.  If you are still unsure, please contact us.
