Our Linkert Velocity Stack solves the age old dilemma presented by the tight bolt pattern around the mouth of the Linkert carburetor. There simply is not enough room for a small flange mount and spun or machined stack. We solved this by designing this critter, and having it cast. The cast body is then machined to perfect tolerances and receives a matched 6061T-6 cap and brass wire mesh screen. We even supply all of the hardware. All you have to do is bolt on and go! Chose from polished or raw body with polished cap.
