Crank Spacer- LS7 Wet Sump Conversion

The Crank Spacer for LS7 Wet Sump Conversion by HOLLEY is an essential component for builders converting traditional dry sump LS7 engines to wet sump oiling systems. This spacer addresses a critical dimensional challenge: when switching from dry sump to wet sump configuration, the crankshaft position relative to the block changes, requiring precise spacing adjustments to maintain proper clearances and engine geometry. Whether you're simplifying a stroker build, reducing complexity on a street engine, or adapting a salvage LS7 platform, this spacer ensures your conversion maintains OEM-level reliability and performance standards.

Engineered specifically for Holley's LS7 wet sump conversion package, this crank spacer is a precision-machined component designed to position the crankshaft correctly within the block assembly. The spacer compensates for the offset between dry sump and wet sump pan mounting surfaces, ensuring the crank centerline aligns with block bore centerlines and maintains proper bearing loads. At just 0.44 lbs, this compact component measures 7.5 x 1.1 x 10.65 inches and integrates seamlessly into the engine assembly process, allowing you to avoid costly frame modifications, oil system rework, or driveline binding issues that occur with improper crank positioning.

This Holley crank spacer is ideal for LS engine platform builders, race shops, and performance enthusiasts tackling wet sump conversions on LS7 applications. It's particularly valuable when working with engine swaps, engine bay repackaging for weight distribution, or transitioning between different oiling strategies without extensive machine work. Proper installation requires alignment during block assembly, making it critical for any builder committed to delivering a bulletproof, street-proven, or competition-ready LS7 build that performs consistently without oil starvation or internal clearance concerns.
