Default Tight clearance with 3.5" PST shaft after 9" install

I'm wondering what you guys did for exhaust/driveshaft clearance for those of you that have upgraded to a 3.5" shaft?

I recently installed a full 9" with a 3.5" shaft from Brutespeed (great service) and I cannot get my exhaust (aftermarket - forget size) to avoid clunking at various times. Did most go with a 3" chromoly to save space or did you massage your exhaust where it needed it? I have to get under there and focus on where its hitting, but wondering if Im the only one with this issue? Maybe I should have just gone with the 3" chromoly...

Thanks for the comment! You should be able to get avoid having any problems with the 3.5" driveshaft. I sell more of these 3.5" alum PST driveshafts than I do the 3.0" chromoly. Make sure the torque arm and Moser torque arm bracket aren't hitting, there are two places where they are prone to hitting the floor. Bob

You're welcome. Check it with the rear in the loaded position. Bob
