I run it on 1.75" with zero issues. I tried without any bumpstops and wasn't hitting anything; pinion yoke would've been a very close fit @ full bump without slightly modifying the driver's side downtube. Full articulation is not a problem, since when the drivers' side is tucked up and pass side drooping, pinion shifts away from the block.
That being said, @ stock height (or lifted with zero added bumpstopping) I wouldn't run a HP D30 without double checking on the exhaust/ pinion interference.
