Brett, if its just the flywheel/pressure plate you're replacing then balancing just those two again by themselves is not worth the effort, they should have had a cursory "balance" job by the manufacturers, ie Mopar & the Clutch maker..........however if you are in the process of rebuilding the engine, ie, new pistons etc then getting the engine balance by the machine shop is a worthwhile thing, even if its only a bog stock rebuild.............balancing would include the pistons,rods,crank,front pulley/damper & flywheel........anyway thats my 3cents worth..........andyd
