Viper 640 Gnav470

Gnav/Boom Vang

Viper 640 Gnav strut
The Viper cockpit is very clean with a gnav in place of a traditional vang. The new 8:1 Harken gnav replaces the slider system with a captive bearing car designed for compression loads. The Harken HC8418 utility car removes most of the friction to make the system more powerful, reducing the need for a very high purchase, and making it far easier to use under load.
