HOT RODS 4170 Stroker Crankshaft

The HOT RODS 4170 Stroker Crankshaft is a complete replacement crankshaft designed to provide the features and benefits of a standard crankshaft while increasing stroke for greater displacement and horsepower. It is factory assembled and trued to OEM specifications, helping deliver performance and durability comparable to or exceeding the OEM crankshaft.

This drop-in replacement requires no modification in most applications and uses the stock piston in most applications. The crankshaft is CNC machined and dynamically balanced to suit the increased stroke. It can also be matched with Cylinder Works Big Bore cylinders for significant displacement and horsepower gains.

The HOT RODS 4170 crankshaft includes original proven HOT RODS connecting rods, top-end bearings, and crankshaft webs. Its gears are manufactured to a quality level of DIN Class 9 or higher, and the crankshaft is fully rebuildable with genuine HOT RODS connecting rods and bearings. It fits select 2006–2009 and 2012–2014 Honda TRX450ER Electric Start models, as well as select 2006–2008 Honda TRX450R models.
