The Hot Rods 4040 Complete Stroker Crankshaft Assembly is a high-quality replacement for select Honda TRX400X and TRX400EX Sportrax models. Designed as a premier alternative to a costly OEM crankshaft, this complete assembly arrives ready for installation with proven Hot Rods connecting rods, top-end bearings, crankshaft webs, and related components. The assembly is factory assembled and trued to OEM specifications to deliver dependable performance, durability, and fitment.
As a stroker crankshaft, the Hot Rods 4040 increases engine stroke to help produce greater displacement and horsepower. It is designed as a drop-in replacement that requires no modification in most applications and uses the stock piston in most installations. The crankshaft is CNC machined and dynamically balanced to accommodate the increased stroke. For additional performance, it can be paired with Cylinder Works Big Bore cylinders to achieve substantial displacement and horsepower gains.
Additional benefits include rebuildable construction using genuine Hot Rods connecting rods and bearings, along with gears manufactured to DIN Class 9 or higher quality standards. This assembly is engineered for riders and builders seeking a reliable upgrade or replacement for their ATV engine.
Fitment includes 2012–2014 Honda TRX400X and 1999–2005 Honda TRX400EX Sportrax models. Manufacturer: Hot Rods. Vendor part number: 4040. Confirm vehicle year, model, and engine specifications before installation.
