Hypertune LS Swap Low-Profile Aluminum Oil Pan Kit for 1955–1987 GM — Rear Sump, 6.0 qt Capacity (302-1)

Hypertune's low-profile aluminum oil pan kit (part 302-1) adapts LS Gen III/IV V8 engines to 1955–1987 GM rear‑wheel chassis, giving a rear‑sump, compact solution with a 5.5 qt sump and 6.0 qt total oil capacity with a stock filter.

This complete retrofit kit is built to let LS1/LS2/LS3/LS6/LSX engines fit classic GM muscle cars, trucks, and other rear‑wheel applications originally designed for small‑ or big‑block Chevy pans. The pan is cast from aluminum for reduced weight and improved chassis clearance, and the package includes the hardware and internals commonly needed for installation. Check compatibility carefully—this pan is not for 5.3L Gen IV applications and the factory dipstick may not work with the new pan.

Will this oil pan physically fit my 1955–1987 GM vehicle with an LS swap?

The Hypertune 302-1 is intended for rear‑sump, rear‑wheel drive chassis that originally used small‑block or big‑block Chevy oil pans. Fitment depends on engine position, crossmember, and steering geometry, and some installations require slight engine relocation for clearance.

• Designed for 1955–1987 GM muscle cars, classics, and trucks.
• Compatible with LS Gen III and Gen IV V8s: LS1, LS2, LS3, LS6, LSX (not compatible with 5.3L Gen IV).
• Rear sump layout and accommodates up to 4.25" crankstroke with full‑length windage tray.
• Verify dipstick and oil filter stud compatibility before ordering.

What hardware and components come with the kit?

The kit supplies the main parts needed for most swaps so you don’t have to source many items separately. All components are new and supplied with a corrosion‑resistant finish on the aluminum pan itself.

• 1× aluminum oil pan and gasket
• 1× sump baffle, pickup tube, and sump plug
• 1× oil filter stud, oil passage cover, gasket, and O‑ring
• 23× bolts included to fasten the pan and covers

How does the pan's construction affect performance and durability?

The pan is cast from aluminum to reduce mass and improve heat transfer compared with typical steel pans, while offering a finished exterior for a clean look. It’s designed to resist corrosion and handle typical engine operating temperatures.

• Lightweight cast aluminum reduces overall engine weight and helps clearance.
• Aluminum surface forms an oxide layer to resist corrosion.
• Improved heat dissipation helps stabilize oil temperature during operation.
• High‑strength casting suitable for road and street use when installed correctly.

Are there installation caveats I should know before buying?

Some vehicle‑specific adjustments are common when retrofitting an LS engine into a classic frame. Pay particular attention to dipstick clearance, oil filter thread/size, and pickup tube alignment—the kit provides a standard pickup and filter stud that may not fit every layout.

• Original factory dipstick may be incompatible; oil level reading could be affected.
• Standard oil filter stud included; use original or an alternative if sizes differ.
• Pickup tube is universal in design but can require a different tube for some blocks or positions.
• Engine may need small positional changes (fore/aft or up/down) for clearance.

Who this is for: The Hypertune 302-1 oil pan kit is aimed at mechanics and enthusiasts performing LS swaps into 1955–1987 GM rear‑wheel vehicles who need a low‑profile, rear‑sump aluminum pan with most installation pieces included. It's well suited for street builds and classic restorations where reduced weight and improved chassis clearance are priorities. If your build uses a 5.3L Gen IV engine or requires the original dipstick, verify compatibility or source the appropriate filter stud and pickup tube prior to purchase.
