High-Capacity GTO Oil Pan for Precise Engine Oil Control
Swapping an LS powerplant into a 2004 to 2006 Pontiac GTO uncovers the factory pan's shallow sump and limited baffling. The GTO Oil Pan corrects these shortcomings with deep sump design, reinforced pickup tube, and integrated windage tray to maintain consistent oil scavenging during hard launches and cornering. Constructed from heat treated forged aluminum, it resists warping during prolonged heat cycles for reliable performance on street or track. Precision CNC machining to factory rail dimensions delivers a reliable seal and hassle-free fit with popular engine mounts and crossmember kits. Together these features protect bearings by maintaining consistent oil pressure under high engine load, ensuring reliable lubrication from idle through full throttle.
Precision CNC Rail Alignment for 2004 to 2006 GTO LS Engines
The oil pan is CNC machined to match the exact rail dimensions and bolt pattern of Pontiac GTO LS engine blocks from 2004 to 2006. This level of precision ensures a uniform seal that eliminates common leak paths and distributes fastener torque evenly across the flange. A consistent rail alignment reduces flange stress under load, so installers achieve a secure assembly without the need for repeated gasket filler or sealant. The result is stable oil pressure at idle and under full throttle, protecting critical bearings and supporting reliable engine performance over time.
Heat Treated Forged Aluminum Structure for Thermal Resilience
Constructed from heat treated forged aluminum, the pan resists distortion during prolonged heat cycles or rigorous track sessions. This material choice preserves the integrity of the sealing surface by withstanding temperature swings that would warp ordinary cast pans. A smooth internal finish further reduces turbulence within the sump, helping to suppress aeration and maintain a clear oil supply to the pump. By combining metal strength with careful forging and machining, the design delivers long lasting durability even under sustained high engine loads.
Integrated Windage Tray and Reinforced Pickup Tube Design
The built in windage tray works in concert with a reinforced pickup tube to counteract oil slosh and maintain consistent feed pressure during hard acceleration or aggressive cornering. The tray separates returning oil from the rotating crank, preventing it from being whipped into foam or starved away from the pump. Meanwhile the rigid pickup tube holds its position against lateral forces, ensuring the pump never draws air during sudden G loads. Together these components preserve a steady oil column, safeguarding bearings over every shift and turn.
Versatile Fitment with Engine Mounts and Crossmember Kits
Beyond performance features, the pan's external profile is optimized to align with popular engine mounts and crossmember kits so installers can integrate it into a variety of chassis without custom fabrication. This compatibility streamlines installation in street rods, muscle car restorations, and track builds alike. Included with the pan are the essential pickup tube, windage tray, gasket, and girdle setup, each engineered to work together for a straightforward assembly process. The result is a robust lubrication platform that supports consistent oil management for daily driving or road course use.
Engineered for a precise fit and lasting performance under all driving conditions.
