Re: Longbed driveshafts

I've got Precision in Tampa building me a 2-pc steel driveshaft. They also recommended i upgrade my pinion yoke (as that would be the next weakest link) so I am doing that as well. Should see everything here this week.

When they asked what my top speed would be I said "you tell me what the limit on the shaft is." In reality, the only time the truck will even see triple digits is in the quarter mile and the occasional freeway on-ramp/short burst (just because). I still have to ask Matt what the critical driveshaft speed will be for my setup but whatever it is I'll just use it as my speed limiter.

I've got 20's all around but should be able to get a slightly taller tire out back when these ones get spent (they're still new).
