I have two brand new ralliart center differentials for the Evo. I ordered them for my friends Evo 6. But he said that they don't fit. I got them from the u.k. long story short, I got hosed by the seller and wasn't able to return them. Now I'm trying to sell them to recoup some of the money. But I need to identify them first. My friend said they look like Evo 7, 8, 9 center diff's. But I'm not sure. The box says Evo 4 though. Any help would be greatly appreciated.

 

The factory center diff is an open 4 spider so its not the stock one. I havent ever seen the RalliArt before so I can't comment on what that is for sure. PM price.

bump

i'm moving at the end of the month. need these gone asap. feel free to shoot me a serious cash offer. lowballers welcome lol

 

I highly doubt that the 7-9 is different than 4-6.

 

I know the 4-6 and 7-9 are different, but I don't know which one these are. I don't own an evo, so I can't check lol

 

Isn't this the VCU that mounts inside the transmission onto the final drive ring gear?

 

Ive never seen a Ralliart Center diff,But i can surly tell you the Center diff is in the trans on Evos,
5,6,7,8,9 the 5 speed quaife part number is, QDH11B for the 6 speed its a QDH13B, for the front diff for Evos the one thats in side the transfer case its a QDH12B. Take a look at some of the pics from quaife, Evo center diffs have 2 diff spline out put tubes on them,and this dont match anything like that.
Im not sure what trans the evo 4 has it in, The 5,6,7,8 and some evo 9"s have the W5M51 5 speed and i can tell you this will definitly not fit inside that trans.

 

^ He's right a center diff should fit in all 5speed evos 5-8

 

The thing in the pics is just the viscous coupling unit, not the diff itself, the diff lives in the gearbox and the vcu bolts onto the front diff which lives in the transfer case.

 

then what is the difference between the evo 4, and evo 5-8?

 

The E4 GSR has the w5m51 trans, For e5 the rear trans mount was added, there was already mounting for it on the e4 casing, the mount just wasnt there.

 

still for sale?
