A propeller shaft assembly includes an inner member having an outer surface with a plurality of splines defining a splined portion, and an outer member having an inner surface with a plurality of splines defining a splined portion. The splined portion of the inner member is capable of being slidably engaged with the splined portion of the outer member to form a splined connection therebetween. One of the inner and outer members includes a tunable energy absorption feature that controls an amount of interference between the inner and outer members. For example, the tunable energy absorption feature can be in the form of a friction ramp on one member that frictionally engages an angled leading ramp on the other member, a raised portion on one or more splines, or splines having different length that can progressively absorb energy during axial deformation of the propeller shaft assembly.
