Koford armatures have won nearly every major race for the past 23 years including the 2017 Nat’s. The advanced technology and exacting quality of Koford arms puts them in a class by themselves. Koford SAW comms are
produced entirely at the Koford factory with computer controlled equipment producing tolerances in the millionths. No competitor has been able to duplicate their unique design which provides superior strength and stability at speeds of 200,000 rpm and more. Koford arms also feature Koford produced 800° epoxy which is available nowhere
else. Heat which will destroy other arms will not affect our arms. Our armature shafts are made from special high speed steel with superior magnetic characteristics and are precision ground, plated with a ultra hard low friction coating which features superior solderability to prevent pinion spinning and resist corrosion, and then they are ground again to achieve diameter tolerances typically in the millionths.
