VW/AUDI EA113 BSD FREEWHEEL MK6R We only stock the STG1This freewheel prevents the balance shaft unit from spinning with engine rotation. This can be desired for high RPM or race focused EA113 builds, to reduce rotating mass, as well as prevent balance shaft failure at high rpm. This will increase NVH around the engines idle RPM, We generally combat this with a higher idle RPM via tuning. Some other benefits also include the reduction of oil temperatures during racing use.
