Switching to CV joint half-shafts will lose about 10 lbs (5 lbs per side); more if you get gun drilled 300M shafts and lightened CV joints. >>>Any vendor in particular, or do they all have the same weight? I'm sure any vendor that sells CV half-shafts can supply 300M gun-drilled shafts and lightened CV joints. It's only a matter of $$$.
