The Yukon Hardcore drive flange, single unit with a 19‑spline inner and 48‑spline outer, strengthens drivetrain internals for serious off‑road use. Intended for Dana 44 applications, this flange kit replaces internal manual locking hub components and helps fortify the axle assembly against damage. Yukon positions these drive flange kits as a heavy‑duty, direct replacement to improve the robustness of manual hub systems in demanding conditions.
