VHM connecting rod is a special lightweight conrod and must be used with the massive big end pin to ensure the best balance factor for minimum engine vibrations.
The connecting rod has 19 grams less weight compared to the OEM connecting rod and improves throttle response.
Through engine braking, standard big end hole of conrod deforms 0,015-0,02 mm oval, while our VHM conrod only deforms 0,005 mm (due to high strength material). In addition, this conrod is also super finished, which ensures a smooth surface. This helps prevent small fractures in the material.
This connecting rod kit inlcudes the conrod, big end pin, big end bearing and washers.
Lightweight
Less oval deformation
High resistance to fractures
Improved throttle response
