Top Street Performance – Satin Aluminum Low-profile Retro-fit LS 5.7 Quart Oil Pan with Added Clearance (Part No.81075)
from
$262.99
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 low-profile, 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. With a different take on our 81073, added cut-outs make the 81075 a great fit with the OEM Ford Fox Body K-member and rack and pinion. This pan also features a boss on each side for an oil return for turbochargers.
