The 3Racing FFEX Idler Gear Shaft was created for the KIT-FFEX to give stronger drivetrain support and longer service life. This shaft handles regular track use and spirited runs while helping the car stay consistent lap after lap.
With careful construction, the 3Racing FFEX Idler Gear Shaft reduces play and wear in the idler area, improving drivetrain efficiency. That translates to steadier power delivery and fewer mid-session adjustments.
Made to fit 3Racing FFEX models without modification, the shaft installs quickly and keeps geometry unchanged. It suits both club-day drivers and racers wanting reliable fitment.
