Carrier bearing drop kit

I’m going to install a carrier bearing drop kit, do I need new bolts or will the factory ones work? If I do need new on what size do I need?

thanks in advance

 

I'm not sure of the exact answer on this but my kid from rough country had everything I needed . But cant remember if it refused the factory ones.

 

I’m 99% certain I reused my stocks. ​

 

It all depends on how the drop kit is designed. You can reuse the factory to bolt to the drop kit to the chassis. If it's a block spacer, you might need to get a longer bolt and apply red tread lock.

 

Factory bolt worked fine for my carrier bearing drop kit.

 

I used stock bolts and put some blue thread locker on them.

 

Is there a certain height before you need to drop it? I did the Rough Country 3” lift level, it didn’t come with anything to drop it.

 

I was just looking at another post because someone was talking about a little shutter the truck does around 1500 rpms on acceleration. He has the same size lift I have and I also noticed a little shutter after the lift. Everyone on that post suggests to do the carrier bearing drop. Now the question is how much should I go with the 2” blocks in the back?

 

Approx 3/4" is what you need.

 

Ok thanks (technically) I could just use some washers right?

 

You could but a solid spacer might be better.


Edit, I used the bed rail spacers from my 5th wheel hitch [had extras]. Worked great.

 

I have 6112s set at 1.9” and had takeoff shudder until I did mine. I’d say it’s needed with any lift, even though mine sits like a stock pro. Since I did it the takeoff shudder went away.

 

Yes this is to correct drive shaft angles from the rear diff to the u joint. In the center of the truck due to rear and front lift but mainly rear.

 

This is what you need. https://www.boss4x4.com/product-p/cb8-cb-.75.htm

 

Thanks just ordered it

 

Thanks @Tundra234 got the spacers today slapped them on and no more vibration.

 

No problem!!

 

Don't want to hijack the thread, but at what point/how do you know if you need a drop kit? Just went up 3" on an Icon kit. Dropped the front diff, but didn't do the carrier bearing. Do I need to?

 

You will know because you will feel a vibration once accelerating from a dead stop. If you lifted the rear at all I would get one. They are inexpensive....about $15.00 or so. I got the vibration after installing a Readylift 3/2 kit.

 

Yep did it to mine no more vibration.

 

Gotcha. Thanks!

 

I’d just do it. They are cheap and take 10 min to install. 5 min of that is crawling under the truck.
