Oh man, I just can't help it... I know... Holy old thread batman...

This is a viscous coupling eliminator. It replaces the viscous coupling and splines the front and rear driveshafts together creating a true 4X4 configuration. 5 minute install with air tools and you shave .1 seconds off your 60' time. 'bout $100.



I just figured it goes really well with the diagram of the Viscous Coupling in this thread. The 4g63 and 4g64-powered DSMs are the only tuner cars that Mitsubishi has ever made.
