Make Your LS Swap Happen Without the Hassle

There is no denying the appeal of the LS swap. GM’s LS family of engines is compact, lightweight, and makes great power. They are plentiful and cheap, and can be found in every RWD application GM has offered since the late ’90s, including performance cars like the Camaro, Corvette, GTO, and G8, and vans, SUVs, and trucks like the Trailblazer, SSR, and Silverado. Furthermore, the aftermarket has embraced the engine family, making an LS swap literally a weekend affair with such LS swap kit bits as engine mounts, headers, cooling system pieces, and more. Perhaps the most popular LS engine is the 5.3L truck offering, as they are the epitome of cheap and plentiful. Most are iron block, though there are aluminum block variants found in certain applications. When swapping most any LS engine you will more than likely need to update the oil pan for proper fitment into the chassis you are swapping into, but especially so with LS truck engines and their deeper oil pans. Our steel LS swap oil pan kit is the perfect solution to your LS swap fitment needs, whether you need an LS3 low-profile oil pan, LS7 oil pan, or any other Gen III or Gen IV LS V8 engine.

Built from The Best Materials to Last

The factory LS oil pan is cast aluminum, and while generally a strong alloy to create automotive components from, you will find excessive casting ribs and bosses to aid in that strength that can be troublesome for fitment in a swap situation. Not to mention if the pan hangs down too far and hits something the usual result is a shattered pan and loss of the sump’s contents and a ride home on the roll back. We make our LS swap oil pans from steel. The steel is just as strong as aluminum without all of the fitment issues, and creates a lower profile while providing for increased sump capacity. If you do happen to strike something with the pan it will most likely leave a dent instead of shattering, allowing you get home under your own power without loss of oil. You will find anti-slosh baffles and four trap doors inside our LS swap oil pan. This creates a diamond-shaped area around the pickup, keeping the oil in place for hard driving like road racing or autocross. So, know a baffled oil pan is preferred over an open design. Our swap pans feature factory-fit pan rails with reinforcement strips that use the stock LS oil pan gasket, a full-flow oil drain with ½-20 threaded drain plug that uses a replaceable nylon sealing washer, and our pans even retain the stock dipstick setup. With just a 6-inch sump depth our LS swap pans are roughly 2-inches shallower than the GM truck pan, and with the pan kickout design we use you get a full 7-quart oil capacity for your LS conversion! Lastly, we coat our LS swap oil pan in a rich black EDP coating for corrosion protection and lasting good looks.

A Direct Replacement Kit for Your LS Swap

Upgrading your LS V8 engine to make your LS conversion happen could not be easier. Our steel LS swap oil pan is a direct replacement for the cast aluminum factory pan found on Gen III and Gen IV LS engines. Due to the shallow sump design we added for additional ground clearance, our pans do require a specific oil pump pickup tube assembly, which is included in our swap kit. This is a direct replacement for the stock pickup, allowing our pan to bolt on easily. While the LS engine’s oil pan gasket is designed to be reusable, and can be reused with our steel pan, we include a brand-new OE-style reusable gasket to ensure your LS swap starts off and stays leak free.

Finish Your LS Swap Faster and Get on the Road

Don’t get stuck on the side of the road with a busted aluminum oil pan! Update your LS V8 engine’s oil pan to one of our strong steel oil pan swap kits before you drop that LS V8 swap into your ride! It is the perfect time to swap oil pans when your LS is on the engine stand getting dressed with your other LS swap kit parts for your swap, so pick up one of our LS swap oil pan kits today and get to swapping this weekend!
