ST180 crankshaft balancer with ATI core

ST180 crankshaft balancer with ATI internal inertia weight to help cancel out engine harmonics! 
The oem balancer is known for shattering and exploding when power levels increase, this balancer replaces the oem pulley with this billet machined hub and aluminium outer shell.
The damper/ pulley is also rebuildable for when the elastomeric rings wear out.
NOTE: removal of the trigger wheel from the oem pulley is required and fitting to the new damper.
For off road use only.
