I know what your mean with the kick while moving and the tries breaking loose ,,, after market valvebody and shift kit defiantly chirp the tires on shift .. when wet they can break loose real easy ..
I just don’t understand why the launch doesn’t rev up like the 30 mph kick . I mean with the tongue these trucks have they should blast of and rev fast from a stand still .. 4.56 gears are meant for the low end rev .
I would think eliminating the coupler and having a one piece shat would put power back to the rear wheels better
