Those with shackles

[0103SVT]

I have had the 2" drop shackles for about 8 months but haven't put them on yet because I'm afraid of changing the pinion angle on the driveshaft. What shims work the best and where did you get them from? I need to know everything about. I've searched and can't really find what I want to know. Thanks

just the shackles will be fine on your truck
most of the 03-04 guys are the ones who need the shims
i know i didnt and i belive you have the same springs as i do

2 in shackles won't hurt. Put them on. :rockon:

yeah see he has an 01 so he shouldnt have to do that, we arnt nearly as high as you are so its not needed

 

[0103SVT]

So taking it to the track shouldn't be a problem either? I've got a ported blower, 6# lower, tune, et streets, and some other little things but nothing more major then that. I would hate to break the u joints or something because of it being lowered. I wouldn't be as mad if I broke it being at stock height LOL.

i have them on my 03 and did not have to flip shims.

I hope your running T-bars with those ET Streets? Just drive it around, and see if you hear or feel anything at any speed.. Then youll know if its right.

Yes. They need to be reversed. The shims are between the leaf springs and the rearend saddle. Loosen the U bolts and reverse the shims.

You'll see the difference when you take them out to reverse them.
