To compliment Hot Rods full line of heavy-duty O.E.M. replacement and stroker crankshafts are Hot Rods complete main bearing and seal kits for both two and four-stroke applications. Like other Hot Rods products, these main bearing and seal kits are built to the highest quality standards that meet or exceed those of O.E.M. Additionally, not only will Hot Rods main bearing and seal kits work in rebuilding a Hot Rods crankshaft; but, they also work in rebuilding O.E.M. cranks as well.
