Re: Question about drive shaft

My 74 and 83 are both long bed trucks and they both had one piece driveshafts. When we did the first swap the driveshaft was actually too short...so we had to get one made.

Re: Question about drive shaft

Research driveshaft critical speed... it can only be so long at a certain diameter at a certain rpm unroll it turns into a wadded noodle. Aluminum can go bigger diameter and thus longer. Just like all bmws, and the camaro, 2 short driveshaft instead of 1 pc means higher critical speed, smaller tube..
