We will try to keep this list updated but if you do not see your engine listed here please ask!  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.

Jeep 2.4 engine found in the longitudinally oriented Liberty KJ and Wrangler TJ; to be sure that you have the correct engine identified, the Mopar oil pan part number is 53010491AA.

Dual steel crank scraper with balance shafts left in place, operating or not:  $114.95; Teflon bladed version $244.95.  This part replaces the stock oil pan gasket.

Dual steel crank scraper with balance shafts removed: $124.95; Teflon bladed version $254.95. Again, this part replaces the stock oil pan gasket.

If you have removed the balance shaft assembly, you have the option of adding a full windage tray assembly.  This is a triple layer tray with louvers, directional screening and a grated bottom level.  There is an anti-slosh baffle with a trap door and Teflon collar for the pickup tube.  The tray has been designed to use the stock oil fill quantity of 5 quarts.  The windage tray assembly requires the dual scraper frame -- it is suspended in the pan by the scraper.

The dual scraper design and windage tray assembly have been well proven over the past nine years in racing and on the street.  Feedback and dyno testing: click here

Steel dual scraper and windage tray assembly: $474.95

Teflon bladed dual scraper and windage tray assembly: $604.95

Mopar oil pan part number 53010491AA


The oil pickup tube is being held in place by jigs so that you can see how it fits within the assembly: it is not included with the kit.
