The Peterson small block Chevy rear crank seal is a single-split rear main replacement for Small Block Chevy engines. Peterson seals are intended for crankcase vacuum applications and are designed to preserve high vacuum levels for improved crankcase control. That makes this seal a practical option for dry-sump systems and other setups where steady crankcase vacuum supports oil management and engine reliability.
