Set of two (2) high performance precision-machined, honed brass crankshaft seal inserts from HRS. One of the key ways to improve engine performance is to reduce internal friction and drag wherever possible. These inserts help the stock rubber crankshaft seals reduce their "death grip" on the crankshaft, while still preventing all air and mixture leakage. Several years of testing in RC applications has shown a typical performance gains of ~.2 HP and ~300 useable RPMs. Improves performance throughout the RPM range
