This ZF6 LLY Duramax rips through the gears like it’s his day job. The shifter he is using is shortened almost 2 inches and kicked back with a 28oz knob. According to the video description this Duramax is getting studs and TCT475 very soon. Also, make sure you turn that volume way up, because this LLY not only revs up quick but sounds badass while doing so. (video below)
