Made from a high carbon steel and weighs approximately 12lbs, this flywheel is for the quickest shifts possible on the DQ250. This flywheel, being a single mass lightweight flywheel, will be louder than an OEM flywheel on start up (sounds like a bell) and slight chatter at low RPMS. The higher speed the flywheel, the quieter it is.
Do your own research on SMF vs DMF before purchasing.
If you are after a more OEM feel and have harmonic dampening of a DMF, look for the DMF adapter on the products page.
Uses 4age ARP Flywheel bolts 203-2802 not included.
