These Stroker flywheels provide 103 or 113 cubic inches of raw power for your Twin Cam engine, by increasing your stock stroke from 4.0" to 4-3/8" and adding the appropriate pistons and cylinders.
- The flywheels and rods are made from high-strength forgings
- The assembly makes use of the Original Equipment (straight press) crankpin and bearings, which mean you get proven durability
