When converting an LS7 with a dry sump to a wet sump oil system, you will need to fill the leftover crankshaft length after changing components. The Holley crankshaft spacer will fill the gap between the damper and the bolt to complete your conversion. Converting an LS dry sump engine to wet sump is common when swapping to vehicles that do not offer room for the oil tank. This process requires removal and installation of several OE parts. One dry sump part not changed is the crankshaft. As a result there is extra crank snout length that needs to be compensated for. Holley's spacer goes between the damper and the damper bolt to fill that extra length.

Fills extra crankshaft length between damper and damper bolt when converting LS dry sump engines to wet sump.

Specially designed to directly work with original and all aftermarket damper /crank pulleys (no additional machining required)

Always use with damper bolt intended for dry sump engine to assure required thread engagement.
