I agree, however, that you may have some front driveshaft vibe problems on a 01 at 4.5 inches, due to the low pinion.

'01 @RE 4.5 + .75poly = No Vibes IF the shop that does your allignments keeps an eye on pinion angle and sets your castor (?) accordingly. But if they drop the pinion, it will vibrate like a bun of a sitch. :shiver:

Good luck.
