How much will a transfer case drop kit reduce the vibration? Is it worth getting? I'm running a RC 3inch

 

You're going to have 20 people behind me say that the T-case drop solved all of their issues but... don't do that.

Assuming you have an NP231 buy an SYE for $140 bucks, install it and get a drive shaft.

If you have an NP242 you'll have to use a Hack-n-tap.

Do it right. You'll be much happier in the long run.

 

It will greatly dampen driveline vibes, but like lowrange said you should opt for the SYE. A t case drop for driveline vibes is like using a fancy steering stabilizer to "fix" dw.

 

What aye do you recommend for 140?

 

*sye*

 

Rugged Ridge.

Seriousoffroad.com has them on sale for $145.00.

 

alright. Thank you

 

I simply used degree shims on the axle. No vibes at 4+".

 

he also runs blocks.

 

Ironrock Offroad makes a sye that's less than $100. I run one and I have never had any issues. This plus a front driveshaft from the junkyard will run you less than $150.

Just giving you other options. The Rugged Ridge one will work great too.

 

When did the op say he had a np231?

 

Don't think he did. But he didn't say he didn't.

 

Nevermind lowrange2 added the right info.

 

This is not the correct way to attempt to reduce driveline vibes at all with single cardan driveshafts. I am not saying that it didn't work for you, but it is not proper at all. You are putting your u-joints "out of phase" by using shims without a double cardan, it puts extra stress on your driveline.

My advice would be (as said before) to do it right the first time with a slip yoke eliminator, a DC driveshaft, then you can put in axle shims.

 

I have done sye's, hack n taps. My advice is to know what you are doing or have someone else do it for you.

I am not arguing about what is "right" or rather politically correct on an internet forum.

I am just saying if you have doubts take it to a reputable 4wd shop.
