Water jet cut flanges are made to ISO 9001:2015 standards with tolerances of +\/- 0.003 inches for extreme precision. We fabricate these over axle pipes using thick gauge aluminum fixtures which act as a great heat sink during the welding process and prevent warping not only of our products, but the fixtures themselves to ensure perfect fitment.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eBOLT ON AND GO:  \u003c\/b\u003eEach set is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure they arrive in perfect condition.
