Product Details
Manufactured from 601 Cast aluminum and are heat treated before being CNC machined. The butterflies are measured for each bore & precision machined to a 0.0005"" tolerance. Butterflies are secured to centreless ground brass shafts with split screws to ensure reliability and serviceability. All are fitted with bearings rather than bushes to eliminate axial shaft movement. Low stiction bearings for sharp throttle response.
We now recommend
and use SKF bearings.
