From Exotek Racing:
New extra heavy duty machined 7075 alloy front pivot mount for the 22-4 2.0.
Must have upgrade to avoid those costly and time consuming DNF’s from failures of the stock plastic pivot mount.
Machined out for lightness (weighs just 17.6gr) and a perfect fit onto the front gearbox.
Includes (2) m3 set screws to lock down the hinge pins.
