Construction & Design:

Crafted from high-quality cast aluminum, this oil pan offers excellent strength-to-weight ratio and superior heat dissipation compared to stamped steel alternatives. The cast construction ensures precise fitment and durability, while the integrated windage tray and baffling system reduce oil aeration and maintain consistent oil pressure during aggressive driving or off-road conditions.

The patent-pending O-ring seal design provides a reliable, leak-free seal between the oil pan and engine block, eliminating the need for messy gaskets. Additionally, the rear-sump layout improves ground clearance, making it ideal for trucks and SUVs where factory oil pans often hang too low and risk damage.

The kit includes all necessary hardware and components for a straightforward installation, minimizing the need for modifications or additional parts.

Integrated lower support bolts secure the engine block to the transmission or bellhousing, adding driveline strength and reducing vibration. The pan’s design also covers the lower bellhousing area to protect transmission components from dirt and debris, enhancing overall drivetrain reliability.
