Product Overview
Strange Oval Grand National Drive Flange
Upgrade your rear-end performance with the Strange Oval Grand National Drive Flange — engineered for strength, precision, and long-lasting spline life in high-demand racing applications.
Manufactured with a lightweight billet aluminum housing and a pressed-in hardened steel splined insert, this drive flange delivers the perfect balance of durability and reduced rotating weight. The hardened steel insert ensures superior wear resistance under extreme torque loads, while the billet aluminum body keeps overall weight to a minimum.
What sets this drive flange apart is its closely mated spline tolerance. Designed specifically to match Strange Oval axle splines, the tighter spline engagement significantly reduces movement and wear. This precision fit extends the life of both the axle splines and the drive flange — providing more consistent performance and fewer replacement cycles.
