The Hot Rods Bottom End Kit is a complete solution for rebuilding the bottom end of your engine. Designed for 1999-2004 Honda TRX 400EX models, this kit includes a factory-assembled crankshaft that meets or exceeds OEM performance standards. The crankshaft is fully rebuildable with genuine Hot Rods connecting rods. Each kit contains everything needed for installation, including a Hot Rods crankshaft, main bearings, and seals, along with a comprehensive engine gasket set for a complete rebuild. Owners can choose between a Heavy-Duty OE-replacement crankshaft or a Heavy-Duty Stroker Crankshaft, which increases stroke length as specified for certain applications. In some cases, cylinder head modifications may be required. This kit ensures a reliable and high-performance rebuild with trusted components, making it a top choice for engine restoration.
