Does anyone know if a 4:1 kit has been made available for the np241c? I know that it is out there for the 241j but have not been able to locate any info. I am going the solid axle route on my '98 GMC when I get back from Iraq this december. I already have the Unimog axles and four inch springs for the front and Offroad Designs' four inch shackle flip. All I need is the 4:1 kit and the slip yoke eliminater. Anyone know anything 'bout this?
