Frequently Asked Questions

Q: What components are included in this kit?
A: This complete kit includes: Precision Koyo and Nachi Japanese crank bearings, and premium crankshaft seals featuring a carbon/fluorocarbon pad on the seal lip and stainless steel garter springs (Manufacturer Part Number: 24-1131).

Q: How do these seals compare to standard factory components?
A: These seals offer a true factory-quality upgrade. The carbon/fluorocarbon pad on the lip provides superior thermal and chemical resistance, keeping the seal soft and effective much longer than basic rubber options.

Expert Pro-Tip: When replacing crank bearings, cleanliness is absolutely critical. Thoroughly clean the engine cases and freeze your new bearings before installation. Freezing them shrinks the metal slightly, allowing them to drop into a heated engine case much easier without damaging the bearing tracks or the aluminum case mating surfaces.
