Greddy Nissan S14/S15 1995-1998 240SX Aluminum Differential Cover
The Greddy aluminum differential cover replaces the stock unit on 1995-1998 Nissan 240SX S14 models. It boosts rear differential oil capacity while adding cooling fins and internal baffles to maintain fluid supply during aggressive cornering acceleration and braking. This design supports track or street performance by reducing heat buildup and preventing oil starvation.
Key Features
- Cast Aluminum Build: A356 aluminum construction resists warping and handles high heat for reliable long-term use.
- Cooling Fins: External fins dissipate heat faster than factory covers keeping differential temperatures lower during extended runs.
- Internal Baffles: Baffles direct oil flow to the pickup tube avoiding cavitation in high-G maneuvers.
- Increased Capacity: Holds more gear oil than stock for improved lubrication and thermal stability.
- Magnetic Drain Plug: Captures metal particles during oil changes extending gear life.
Product Notes
- Supplied with neoprene gasket for leak-free seal.
- Drain existing differential oil before installation.
- Packaged in sturdy box for safe transit.
Installation Notes
- Professional installation recommended.
- Bolt-on replacement using factory hardware.
- Torque bolts to Nissan specifications after gasket placement.

Diff Covers
Differential covers protect the ring gear, bearing caps, and gear oil inside your axle housing. Upgrading from a factory stamped-steel cover to a cast iron, billet aluminum, or fabricated steel unit adds extra fluid capacity for better cooling and provides significantly more impact protection on trails and tracks.Popular Diff Cover UpgradesTop sellers include Dana 44 and Dana 60 covers from Yukon Gear and ARB, deep-sump covers for GM 8.5-inch and 10.5-inch axles, high-clearance covers for Jeep JL and JK axles, and aFe Power COVER axle covers for Ford F-150, Ram, and GM truck platforms. Many billet covers add fill-plug temperature ports for monitoring fluid temps under tow.Do aftermarket diff covers actually help?A thicker-walled cover increases gear oil capacity by one to two quarts on most axles, reducing operating temperature under sustained load like towing or trail driving. Reinforced covers also resist rock strikes that would crack or bend a stock stamped unit, keeping your dif...
