What makes this seal suitable for the repair environment?

Fel-Pro uses proprietary materials and an application-specific design that accounts for imperfect sealing surfaces. This ensures a reliable seal even when the mating surfaces aren't factory-perfect, which is common during repairs.

Does this crankshaft seal come with any installation hardware?

This product is the crankshaft seal itself. Installation hardware, such as bolts or O-rings not integral to the seal, is typically sold separately. Always refer to the manufacturer's instructions for a complete parts list.

What is the warranty on Fel-Pro crankshaft seals?

Fel-Pro typically offers a limited warranty on their gaskets and seals. Specific details can be found on the manufacturer's warranty documentation, which usually covers defects in materials and workmanship.
