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

Windage tray sump cover:

A triple layer windage tray is available that mounts to a 4.0 girdle.  The windage tray acts as a rearsump cover to shield the oil from pulses of air.  There are louvers and directional screening with an additional lower layer.  These design elements are borrowed from the successful SRT4 tray set. Copyright 2002-2023 © All rights are reserved on our product designs. $254.95

There are two options: 1) have the full length girdle included; 2) the girdle can be shortened so that only the last three brackets are used.

Here are some things to consider:

The main bearing brace was added by Mopar in 1996 on the 4.0.  It is important to realize that the oil pan was also modified to allow room for it so if you add it to an earlier engine that is an additional item that needs to be modified or changed.  Also, if you are using a 258 crank in your 4.0 block, the increased stroke will not clear the brace without the use of spacers, which makes the fitting issue with the pan larger.

If you choose the shortened version you will have far fewer fitment issues on earlier oil pans and for larger stroke crankshafts.  Also, if you plan on shortening it anyway it will save money on shipping cost.
