Moroso 20178 GM LS Swap Rear Sump Steel Oil Pan for Chevy S10 & Blazer

The Moroso 20178 is a high-performance GM LS engine swap rear-sump steel oil pan engineered specifically for Chevy S10 and S10 Blazer LS swap builds. Designed to solve the clearance and oil control challenges that come with dropping a Gen III/IV LS engine into a compact chassis, this pan provides a purpose-built solution that outperforms modified OEM pans.

Key Features:

• Rear sump design — optimized layout for S10/Blazer LS swap applications, providing critical ground and crossmember clearance
• Steel construction with a precision laser-cut rail for a reliable, leak-free seal
• Wet sump configuration — compatible with the factory-style GM LS oiling system
• Anti-slosh baffling — helps keep oil around the pickup under acceleration, braking, and cornering
• Compatible with GM Gen III/IV LS series engines (LS1, LS2, LS3, LS6, and related variants)
• Designed to clear stroker crankshaft assemblies — check dimensions for specific stroke clearance
• Works with Moroso oil pump pickups designed for this pan (sold separately)

Moroso's LS swap oil pans are part of a fully integrated oiling system lineup, allowing builders to pair this pan with matching Moroso oil pump pickups, windage trays, and accessories for a complete, race-proven oil management solution. Whether you're building a street truck, autocross car, or drag strip weapon, the Moroso 20178 delivers the fitment and performance confidence your LS swap deserves.
