Toyteclifts.com I’m running their aluminum degree shims and U-bolts quality stuff.

 

Get steel...the aluminum ones will crack over time

 

It depends if you are removing your leaf pack ? If you are just trying to fix vibrations than I would suggest getting shims with open slot so they can just slide right in. https://www.headstrongoffroad.com/s..._pins,_bushings,_shims,_and_brake_lines).html

 

Do you really need shims, especially 3 degrees? You should be able to find some easy from a google search but I would stay far and clear of aluminum and nickel.

 

Thank you

 

So what stops these from popping out? It’s a wedge clamped between two flat pieces. It’s going to eventually work it’s way out.

Edit: N/m. I see now that the opening is opposite the direction it would walk out.
