Designed for builders tackling custom K-series engine swaps, these K20/K24 oil pan flanges eliminate the most difficult and time-consuming part of fabricating a custom oil pan. In many rear-wheel-drive and non-standard swap applications, off-the-shelf oil pans simply don’t clear the subframe, steering, or crossmembers—making a custom pan the only real solution.
The flange is the critical foundation of any oil pan, and getting it right is often the hardest part. These flanges are precision-cut from 4.5mm thick steel and are ready to weld, allowing you to easily build the rest of the pan to suit your exact clearance, capacity, and pickup requirements.
Once welded, you can design the pan depth, shape, and baffling exactly how your setup demands—without fighting fitment issues or modifying factory pans.
