This is the most versatile method of keeping your wastegate closed when switching to an external wastegate. The CNC machined bracket allows rotation along the compressor housing. This allows fitment across different VF, TD04\/5 and DOM series turbos if you should upgrade in the future. The dual spherical bearing linkage makes installation a snap and can be easily reverted to a stock set-up. The center turnbuckle allows you to easily close the wastegate. Turning one direction lengthens the linkage. Turning the other way shortens it.\u003cbr\u003e\u003cbr\u003eThe wastegate bracket is engineered and manufactured at our facility in Westminster, MD. The bracket is machined from a solid piece of 6061 billet aluminum and then anodized black. The linkage is made entirely of steel components and is zinc coated for corrosion protection.
