Kaaz Center diff with VCE or with Stock VC

[mattp_65]

I have been reading through the forums. Question is that I have a Kaaz Center Diff with a Viscous Coupler Eliminator (VCE) installed right now. I am having a used Stock Viscous Coupler (VC) being sent to my house. Is it necessary to keep the VCE or use the Stock VC?
I have read that VCE is not needed for daily driving only for FWD dyno.
I have been driving like this for years and no major problems with my trans except worn out syncros (but besides this everything is good).
I bought the Stock VC so I can switch it out with the VCE, but I wanted your guys' opinion on this matter.

Let me know what you guys think:
Keep VCE or use Stock VC on my 4gear spider Kaaz Center diff?

thanks in advance
Matt

Kazz Center Diff is LSD so stock Viscous Coupler is not needed. Kazz center is a cluth type LSD but, if you instaill it it could only help. They can both work together to control the torque split between front and rear.

Stock Ciscous Coupler is terrible at controlling torque spit by itself. A member dyno his car on awd dyno and the front is split in access of 60% while the rear recieved only 30%.

Remember, our car are geared to revieced 50% front and 50% rear but that is not alwasys the case. The power that the engine put out is going to the gearing that are less resistant. Kazz and stock VC attempt to split the power equally between the front and back. Kazz do it better with its clutch system. Both does the same.

So you are saying that it is not necessary to use the Stock VC with my Kaaz center diff, but if I install the Stock VC and remove the VCE it will help alittle.
Which way should I go Stock VC or stay with VCE?

thanks

I'm not totally sure how the center limited slips work so I can't say for sure if it's worth putting in a viscous coupler or not, however I am completely sure of what the vce does and when it should be used and you should not be using it with anything other than a welded center diff. The stock viscous coupler is essentially acting as a limited slip, a vce essentially locks the shafts together as a welded diff does however the vce by itself is much weaker than a welded diff. So for however long you have had your kaaz unit installed it has not done anything for you since your vce has your shafts locked.

Remove the VCE. its not good to leave it in. from what i understand VCE is designed to lock up both front and rear gears together, so when you are on the front wheel drive dyno you can disconnect the transfer case. If you are leaving it in you are not letting kazz lsd do its job. it's going to cause binding issues.

In regards to putting in stock viscous its up to you. They both design to do the same thing except kazz do it 10x better. the only reason i can think of using stock viscous with kazz is to promote longevity of the plates in the kazz lsd.

remove the VCE as soon as you can. There is absolutely no reason to run with a limited-slip diff if the VCE lock the front and rear together. There is no more limited slip action, it's fully locked like if you had it welded.
