CMI Precision: The Ultimate Drag Racing Swing Axle Set
Engineered for Maximum Launch. Guaranteed Unbreakable.
When "good enough" isn't an option for your '61-66 Sedan, CMI Precision Machining delivers. These aren't just replacement axles—they are over-engineered masterpieces designed to survive the violent torque of competitive drag racing.
Forged from aerospace-grade 300M steel, every axle undergoes a meticulous hand-polishing and lapping process to achieve a 4 Max RMS finish. This isn't just for looks; it minimizes friction and maximizes component longevity under extreme loads.
Why CMI Axles Lead the Field:
-
Race-Ready Threads: Features a specialized J-Thread with a 0.3mm root radius, specifically engineered to distribute stress and prevent fatigue failure during hard launches.
-
Corrosion Protection: A sleek Black Oxide finish provides a high-end aesthetic while forming a durable barrier against rust and environmental wear.
-
Premium Hardware Included: We don’t ship these with hardware-store bolts. Each set includes heat-treated 17-4 Stainless Steel thrust washers and nickel-plated 4340 flanged castle nuts (hardened to 54-56 HRC) for a total-package upgrade.
