LS engines are among the most popular for swaps for their low expense and great power potential. Unfortunately, stock LS oil pans can’t always fit where you want them to. That’s where TSP’s retro fit oil pan comes in. Composed of lightweight cast aluminum, it is designed to allow for increased clearance to the ground and chassis. It will fit many GM rear-wheel drive applications originally equipped with a small or big block Chevy engine and factory rear sump pan. Meticulously designed, it will mount perfectly to any wet-sump LS engine and take the stock oil filter.
