Degree shims with dakar pack

Im going to be putting in my left soon.

I know that ever truck seems to be a crap shoot for post lift vibes but the overwhelming result seems to be using a 3 degree shim.

I plan on taking my overload lead out for a little less lift.

Any help on shims for the dakar pack with over load removed? I have the extended center pins. Was thinking of maybe getting some shims ahead of time.

2 degrees? 2.5 degrees?

 

No one?

I had heavy duty dakars, and aligned my leafs with both 2.5 degree and 3 degree shims, measuring my drive line angles along the way.

I found that the "1 degree per every inch of lift" is pretty much dead on. 2.5 degrees will probably be your sweet spot if you're running the heavys with an overload removed. I don't think theres a good source for steel 2.5 degree shims, all-pro makes some nice 3 degree all steel encapsulated ones. The aluminum slide in ones are nice when you're finding your sweet spot, but not a good long term solution IMO.

Don't drop your Carrier Bearing either. OME provides a block for this, but its the wrong way to correct your driveline.

 

I use 3 degree shims and the OME carrier drop on my 2nd gen. I have never heard of a problem with the carrier bearing drop. I would recommend them both.

 

The problem with a carrier bearing drop is that you're playing with an angle that you shouldn't have to touch at all. The angle coming out of your transfer case and into the first part of your driveshaft, ending at the carrier bearing remains completely unchanged when you lift the truck. You want that line coming as straight as possible out of the transfer case thru the 1st half of the shaft, which is as straight as possible from the factory. . People use the support bearing drop because its much easier than installing shims, although I recall other members using very small washers to make minor adjustments on their CSB ( a few decimals of degrees) which I doubt would have much of an impact.

Highly recommend watching and understanding this entire video before messing around with your driveline and blindly trying shims or bearing drops.

They have 2 and 2.5

I got the center pins already too cause it was cheap insurance to just toss in ahead of time

 

What you ended up with?

 

Started out with 3. Had vibes. Ended up using none.

 

Just an update I did installed a 3 degree axle shims and fixed all vibs or shudder specially on deceleration.
