Fluidampr Balanced Damper Subaru WRX 2002-2014 / STI 2004-2021

Definitely plan to do this while doing a timing belt service. I unfortunately didn't, and modifying the belt cover required removal, which was way harder with the radiator in place.

Improvement in engine smoothness is noticable, and the trouble caused by the lightweight pulley I installed while doing the timing belt has been resolved completely. Do not buy any other pulley than this one!

It’s exactly perfect. No issues going through tech.

This is a pretty good fluidamper balancer to have if you have to replace the OEM rubber one.

Don't build an upgraded engine for big power without getting one of these. Made a noticeable different in idle and drivability smoothness after installing.

Every subie should have one of these dampers installed when you start adding HP. Right under an AOS should be this damper on the mod list.

This is one of those reliability mods that I can’t say enough about, especially when increasing power

Got it on sale

Car had pops on decel after install O YEAH!

Great craftsmanship, very easy to read timing markings.

Incredibly high quality piece. Works as intended and is machined to fit better than stock. A must-have for mid to high horsepower applications.
