Sb Crankshaft Wiper

The Moroso SB Crankshaft Wiper is a precision-engineered component designed to manage crankcase vapor and oil mist in small-block Chevrolet engines during high-performance operation. Built for engine builders and street rod enthusiasts, this wiper addresses the issue of crankcase pressure buildup and oil carryover that can occur in modified engines.

This wiper operates through direct contact with the rotating crankshaft, utilizing engineered wiping elements to separate oil and vapor before they exit the crankcase. The design minimizes pressure spikes that can damage seals or gaskets while maintaining optimal ventilation for engines with increased displacement or forced induction. Moroso's precision manufacturing ensures reliable separation performance across a broad RPM range.

Small-block enthusiasts working on modified engines, high-compression builds, or forced induction setups will find the Moroso SB Crankshaft Wiper beneficial for maintaining engine performance. Its compact footprint and lightweight design facilitate installation in tight engine compartments without compromising durability.
