Budget Boost Question

I currently have a 3" Rusty'a lift with a full length real AAL. I was thinking of adding a RE Budget boost to the mix with the coil spacer and extended shackle.

My question is, will I have to make any adjustments to the T-case? I currently have it dropped and have no driveline vibes. Will adding a budget boost change the driveline angles enough to where I would have to go to a SYE?

Thanks

It depends on several factors, one being the year(post 96 are prone to problems when you lift). I'm sure someone out there has 5-6" and no vibes but it's likely that you would need to go to a SYE. You might try tapered shims first. That works for many people

My son has the same setup you describe and has no driveline issues.
