Thread: Drive shaft yoke insertion limits

Tweet

We are thinking of moving my Dad's 31 chevy rear axle back about an inch to get the rear tires more centered in the wheel wells. We 'd love to be able to do this without having to have the drive shaft lengthened. We are wondering your guys opinions on the minimum amount of insertion the front yoke can have into the trans (turbo 350).

Switch to a longer yoke , Spicer part number 2-3-10391X has
a 4 3/4" long splines

Thx Hawk, its good to know that we have that option. I am just not sure at what point do we decide that the amount we have is not going to be safe...
