Complete Set of Vanes With 3/8" Hardware, 1/8" Vane Height

A&I rotor vane kits use 3/8" hardware throughout. If installing on a Lowen/A&I rotor cone, no modifications will be needed. If installing on an OEM rotor cone, 5/16" holes will need to be drilled out to 3/8". If customer has an AFX rotor, install per the instructions in your operators manual. If the customer DOES NOT have an AFX rotor, the will need to cut off 7-5/8" from the FLAT END of the long vanes. The vanes will then be the same length as the originals and the holes should line up. If the customer wishes to use the full length vanes, matching holes will need to be drilled in the rotor cone for installation. See A&I website for bulletin on p/n A-437319A2.
