2.25" OD Carbon Fiber Drive Shaft for Circle Track Racing.  2.25" OD carbon fiber tube with .125" wall thickness. Aluminum bond yokes.  We have built and tested these since 2019 before releasing to the public.  Solid 1310 u-joints are stronger since the cross is not drilled for a zerk fitting. Carbon fiber drive shafts are safer in the case of a transmission or rear end failure.  Specify center to center measurment on the u-joints. Also available with a slip yoke installed.  

Bigger sizes are available in 2.75" OD, 3.25" OD, 4.25" OD and 5.25" OD for heavier duty applications like offroad or drag racing.
