It’s kind of cool realizing that my Chevy 350 small-block and TKO 600 trans are finally getting close to hitting the open highway. But wait, I may be overlooking something – oh yeah, the driveshaft. If the shoe fits, wear it, right? Well no, you spent good money on that V-8 you just hopped up and that new upgraded transmission may end up a different length than the stock three speed.
My question is this, why would you overlook the weak link? It’s true that the tiny stock driveshafts that came with the straight-six trucks were not made to handle the power of a V-8, let alone the higher rpm’s. Worn U-joints will most likely hold up with straight-six engines, but put on some sticky tires, drop in a V-8, or do any performance driving and you will be asking for trouble.
Ever do a burnout on a back road thinking everything was OK? Now imagine that same burnout ending with a bang because your U-joint broke or driveshaft twisted like a pretzel. I’ve seen what happens when a U-joint gives way, and not only could it damage your tailshaft housing, but it could also crack the transmission case. Not good! On the other hand, a replacement driveshaft, or possibly a longer or shorter driveshaft to fit the new concoction under the hood, may be the only thing you need.
With the driveshaft in and tightened down it really completes the drivetrain. Looks, performance, and drivability all in one driveshaft.
