This McLeod steel flywheel is a 143-tooth unit for Mopar big-block six-bolt crank applications and is offered for a range of 340/360/383/440 engines. CNC-machined from billet alloy steel and fitted with a 1045 hardened ring gear, it suits street use where easier stop-light acceleration is desired and is also recommended for heavier-duty off-road or race launch scenarios where a steel flywheel’s mass is beneficial.
