Carrier Bearing Drop Question

I'm planning on lifting the back of my Tundra in the next couple of weeks with the ICON 1.5 rear spring expansion pack and +3 Coachbuilder shackles. Also using the OME rear sport shocks.

This combo would result in a 3.25 total lift. Should I use the CB 0-2 carrier bearing drop kit or the 3-4 in this situation?

Thanks

 

I would use the 3-4.

 

Better yet, install the springs and see if you even need this. I'm running ICON RXT springs at Config 2, ~3" lift when loaded. I don't get any vibration from the driveline, if it ain't broke, don't fix it.

 

Read this recent thread as it is applicable to you. The OP gave up right before the solution was found. Making a guess at what your operating angles should be may lead to unnecessary frustration and confusion.

What I would do is install your new setup (temporarily reusing the original Ubolts) and then take the measurements to calculate what corrections you need to make. You might need a shim to go under the leafsprings. Once you have the solution in place then permanently install using the new Ubolts.

 

The videos you posted in that thread are what you're talking about, right? Where would I get the shims for that if I needed them?

Your truck looks awesome BTW.

 

That’s correct. You can find shims on Amazon, just do a search for 2.5” leaf spring shim. They’ll have varying degree shims.

 

Thank you.

 

Just for reference I have a 2.5 inch lift in the back, I used CB 0 to 2 inch spacers then added 2 standard washers on each side for good measure. I didnt try driving without it first but I'm not getting any vibes so I'll leave them on.
