Complete Bottom End Kits

Description

The Hot Rods Complete Bottom End Kit provides everything needed for a full crankshaft installation, including a reliable Hot Rods crankshaft, main bearings, seals, and a complete engine gasket set for a full rebuild. The crankshaft is factory-assembled to OEM specifications and is fully rebuildable with genuine Hot Rods connecting rods. This kit offers a choice between a Heavy-Duty OE replacement crankshaft or a Heavy-Duty Stroker crankshaft, which increases the stroke length based on the application. In some cases, cylinder head modification may be required. For the 2002-2014 Yamaha YZ85, the stroker crankshaft adds a +2mm stroke, increasing displacement to 103.5cc (cylinder head machining required).
