We now offer a nice EXTRA THICK reproduction of the very hard to find rear sump truck oil pan. This was originally sold as Chrysler part number 3577640 and 4027236. Factory Chrysler Oil pans, and the "made in Taiwan" reproductions on the market are usually made from steel which is about .049" thick. We've reproduced these in our EXTRA THICK steel, which is about .083" thick, or about 70% thicker than normal. The extra thickness not only helps to keep the pan more rigid and the pan rails straight and flat, but it also helps if you accidentally scrape the pan on that odd speed bump or driveway. These are about 6" deep and hold 6 quarts of oil, plus one in the filter, for 7 quarts total. Will not fit stroker windage trays, can be used with stock stroke windage trays only. We also carry the matching oil pickup (111-1002), dipstick (111-1001), and dipstick block hole plug (109-1560), all of which are required to use this pan.
