Centering Ring Kit 3.9" x 75mm
These CNC precision cut three piece centering ring sets have a 3/8" fore ring with an integrated harness attachment system (3/8" Kevlar booster harness & pin included), a standard 1/4" center ring, and a 3/8" aft ring with a stepped OD that doubles as a thrust ring against the airframe. This combination increases strength and reduces weight. Kits come with your choice of a 12" or 24" long Kraft Phenolic motor tube.
Note: Centering Ring Kits are sized to fit our canvas phenolic airframes.
