Hypertune LS Swap Retrofit Aluminum Oil Pan Kit — Low-Profile Rear-Sump (302-1) for 1955–1987 GM

This aluminum oil pan kit was engineered for classic GM muscle cars, trucks, and restorations that convert to LS-series engines and need extra chassis clearance without sacrificing oil capacity or durability. It offers a 5.5-quart sump volume (6.0 quarts total with a stock filter), a cast-aluminum construction for light weight and corrosion resistance, and a layout intended to accept a full-length windage tray and up to 4.25" crankshaft stroke. The kit ships complete with gaskets, pick-up tube, sump baffle, oil filter stud and hardware so you have the main pieces required for many swaps.

Will this oil pan fit my 1955–1987 GM swap project?

The pan is made to mate with LS Gen III engines and many Gen IV conversions in classic GM RWD chassis originally designed for small- or big-block Chevys. It is optimized for rear-sump applications and specific LS engine offsets. Verify vehicle- and engine-specific clearances before ordering.

• Compatible with LS1, LS2, LS3, LS6, LSX 4.8L–6.2L (NOT for 5.3L Gen IV)
• Designed for 1955–1987 GM cars and trucks with traditional rear-sump pans
• Maximum crank stroke supported: 4.25"
• Part number: 302-1 — confirm fitment with your engine and chassis

How does the Hypertune pan improve clearance and weight for a swap?

Cast aluminum construction reduces weight compared with many steel or factory pans and offers a low-profile shape that increases clearance to crossmembers and subframes. The exterior is styled cleanly to clear chassis components while preserving enough sump depth for oil control during spirited driving.

• Lightweight aluminum lowers front-end mass for better handling
• Low-profile rear-sump design maximizes chassis clearance
• Cast finish resists corrosion and sheds heat faster than steel
• May require minor engine repositioning (fore/aft or height) in some swaps

What comes in the kit and what might I still need?

The kit includes the oil pan plus a full set of commonly required components for installation, but some vehicles need different filter studs or pickup shapes. It’s sold as a complete retrofit set but you should check the oil filter stud size and dipstick compatibility for your specific build.

• Included: oil pan, gasket, sump baffle, pick-up tube, sump plug, oil filter stud, oil passage cover and gasket, O-ring, 23 bolts
• Oil capacities: 5.5 qt sump; about 6.0 qt total with standard stock filter
• Note: universal pickup tube may require modification for certain engine layouts
• Note: original factory dipstick may not work with this pan without replacement

How does this pan handle durability and oil control?

The cast aluminum pan resists corrosion, dissipates heat effectively and supports a full-length windage tray to reduce oil splash and windage losses. Internal baffling and the supplied pickup tube are intended to keep oil available at high cornering or acceleration loads, though some installations may need custom pickup alignment.

• Anti-corrosion cast aluminum body with durable surface finish
• Sump baffle and pickup tube included to improve oil control
• Designed for windage tray use and increased crankshaft stroke tolerance
• Rapid heat dissipation helps stabilize oil temperature under load

Who is this for? This Hypertune LS Swap Retrofit Aluminum Oil Pan is aimed at restorers, hot-rodders and professional builders converting 1955–1987 GM chassis to LS Gen III (and compatible Gen IV) engines who need a low-profile, durable rear-sump solution. Choose this kit if you require improved chassis clearance, lighter weight, and a largely complete hardware package — but confirm filter stud size, pickup tube routing and dipstick compatibility for your specific engine and chassis before purchase.
