To compliment Hot Rods full line of heavy duty O.E.M. replacement and stroker crankshafts are the Hot Rods complete main bearing and seal kits for both two and four-stroke applications. Precision, high-quality main bearing and seal kits complement Hot Rods crankshaft assemblies. All kits contain two main bearings and two seals, except where noted. Additionally, not only will this kit work in rebuilding a Hot Rods crankshaft; but, it will also work in rebuilding O.E.M. cranks as well. Note: May NOT include seals; if not included, they are not needed.
