Fuller Hotrods HR00246 Heavy Duty Stroker Complete Crankshaft Assembly

The Fuller Hotrods HR00246 is a Heavy Duty Stroker (HDS) complete crankshaft assembly engineered for powersports engines demanding both increased displacement and enhanced durability. This assembly delivers more horsepower and torque compared to a standard OEM-stroke crank, while being factory assembled, trued, and balanced to OEM specifications right out of the box.

Built on Hot Rods' proven heavy-duty platform, the HR00246 adds material in high-stress areas of the connecting rod forging to create a significantly stronger rod that resists deformation, keeps bearings in better condition, and outlasts standard OEM components. A bronze bushing inside the wrist pin bore further reduces wrist pin galling and improves load resistance — making this assembly ideal for big bore, high compression, or forced induction builds.

Key Features:

• Heavy Duty Stroker design — increases engine displacement for more torque and horsepower without costly case machining or custom cam chains
• Factory assembled and trued — balanced to OEM specifications and ready to install with no additional tuning required
• Reinforced connecting rod forging — additional material in high-stress zones resists deformation under extreme loads
• Bronze wrist pin bushing — reduces wrist pin galling and improves loading resistance for long-term durability
• Complete assembly — includes Hot Rods connecting rod, top-end bearings, and crankshaft webs
• Fully rebuildable — compatible with genuine Hot Rods connecting rods and bearings for future rebuilds
• Meets or exceeds OEM parameters — subjected to a full system of quality control checks and rechecks

The HR00246 HDS crankshaft assembly is the ideal solution for engine builders looking to increase displacement and performance while maintaining a bolt-in fitment profile. Most applications use the stock piston, keeping the build straightforward and cost-effective.
