1410 Series Super Flex, Offset Universal Joint Product Description:

Super Flex U-Joint

The unique design of off-set trunnions sets the mating yokes farther apart than a more conventional joint. This allows for 10 degrees more flexibility than would be otherwise obtainable. While 10 degrees may not sound like a lot, with a 30″ drive shaft, this will allow more than 5″ of additional droop at your axle prior to binding of the universal joint. 

Available in 1310, 1350, and 1410 series. 

IMPORTANT: THIS JOINT WILL CAUSE DRIVE SHAFT VIBRATIONS. It is not compatible with double cardan (cv) assemblies. It should not be used in high speed applications.
