Re: Driveline/u-joint angles…

So I’m bringing this post back from the dead. What are you guys doing with lowered trucks and unjoint angles? I ended up lowering my truck a couple more inches- probably close to or a hair more than a 4/6 drop. The engine sits 4.7 degrees down and the driveshaft 1 degree down and as a result I have a 3.7 ujoint operating angle. Spicer says not to exceed 3 degrees. The tranny mount is already shimmed up and I don’t think I can go any higher without the driveshaft hitting the top of the trailing arm crossmember at full suspension travel.

Are you guys with dropped trucks just running the ujoints over these recommendations? Any vibration issues?
