I know a buddy of mine put AN 8.8 ford traction loc differential in his gen 1 Lincoln ls 8.0 rear. Is that the same as ours? if so has anyone done this? I thought I read something about it awhile back..But didn't refind the info


Thanks

 

Totally different axle spline count and would never work , Sorry

 

None of the cars in your signature match the section of the forum where you posted.

That only confuses matters.

 

I think you meant to put this thread in the X350 section? so i've moved it for you...

The diff in your X350 is a Gen2, same as the S-Type from MY2002.5 onwards (also the first alloy-body X150 XK and the first XF's) the Ford 8.8" LSD center does not fit in because the housing is too small.

Very long thread in the S-Type section about it https://www.jaguarforums.com/forum/s...install-86430/

Also check out this thread, gives an overview of the diffs fitted in the later model Jags. https://www.jaguarforums.com/forum/j...ntials-134733/

If you want an LSD in your XJR, there are two options;

Quaife

or

Try to fit a complete Gen1 from the early S-Type, but so far no-one has done this to an X350 AFAIK, only S-Types...

 

I don't know how I posted here. SORRY GUYS!!! I have a 2001 xkr and a 2004 xjr. This was in regards to the 2001 xKR.


As I mentioned a buddy of mine with a 1st gen Lincoln LS used an 8.8 28 spline differential in his 8.0 housing with no modifications, I was curious if anyone has tried this in their early model xjr or xkr rear ends. I read somewhere that they used the same 8.0 setup


Again sorry! I was looking for this thread today and couldn't find it...DUh!

 

Ah ok.

Well the answer is no. The diff in the X100 XKR has absolutely nothing to do with the Ford/Lincoln 8.8"

For the X100 XKR you're looking at a Quaife or an OS Giken. Or doing a conversion from an X300 LSD.

 

OS Giken doesn't make the part any more and were quite adamant about never making it again.

Quaife or fit the power-lok from an older XJ.

If you decide on a Quaife, do not try to source it in America. Waited more than 6 months before finally giving up and canceling the order. Ordered from out of the UK and had it in 2wks.

 

So the differential in my 8.0 housing is nothing like the one in the 1st gen Lincoln ls?

 

Not even a little bit.

 

1st you need to decide for yourself what type of diff you want, although if you want the 8.8, I take it you prefer the clutch versions (I especially like them as well over the ATB ones). Besides the options mentioned (so x300 diff), you also have a gripper diff from the UK (had this one before with good experiences). With this one you can have custom ramp angles if you like, and is including fitting to the pumpkin priced ok, though in the uk of course.

 

I do prefer the clutch version. I have used Torsens in the past and I am just not a complete fan of the feel. Ill look into that gripper diff. Do you have a contact? I'm also going to have to get a spare pumpkin to play with regardless. Whats killing me is that I know that the 8.0 differential was replaced with the 8.8 differential in my buddys Lincoln ls with no modifications, the ring gear even bolted right up. And I'm not trying to be stubborn here. I'm only going by what I was told and I really don't know of the differences between a Lincoln LS differential and the xkr. Im an engineer....I cant help but to tinker

 

There is absolutely no commonality between the diff in the X100 XKR and the Lincoln LS. Forget it.

You are probably getting mixed up because the X350 XJ, S-Type and the first XF's & X150 XK's used a similar diff. But these are totally different to what's in your X100 XKR.

Jag 14HU or 15HU has nothing in common with the Ford 8.0" / 8.8", nothing at all.

 

So Jaguar actually used different differential units inside the housings for all of these different cars. I'll believe you I just find that strange for many different reasons. Ill revisit this when I actually do something with my rear. Thank you all for your insight

 

You have to remember that the X100 XK8/R was a development from the XJS. At the same time the X308 XJ was a development from the X300, which was developed from the XJ40. So the diffs were based on the old Jags, not the new "Ford" Jags. The S-Type was a completely new platform for Jag, which borrowed heavily from the Ford supply chain. The X350 XJ was also a new platform, completely unrelated to the previous X308, but shared a lot in common with the S-Type.

They are completely different vehicles, on completely different platforms, that happened to be built at the same time. It wasn't until the alloy-bodied X150 XK that the XK, S-Type and XJ were all unified in their drivetrain & chassis.

 

Here is where I bought the gripper diff from:
gripper

It was many years ago, so don't know the actual prices anymore, I may have gotten a good deal as I was the 1st.

 

Cambo. Yeah Im aware of most all that..MOST. I didn't realize it was a carry over from the xjs at all...Spoiling all my dreams. Now Im wondering if I should just drop my entire subframe when I rebuild the bushings and all :O)
Im looking into the gripper. Ill let you guys know!

 

Seems around 1200 pounds...Which is a heck of a lot! ..About $1,800 USD...WIll crazy glue work? :O)

 

When looking at their price list it's 1020 pounds (Alu bodied one is 1200…), if that is still including fitting in the pumpkin it’s not bad (even cheaper than the Quaife), better to ask them.

 

Gripper has indeed raised the prices, they confirmed 1200 gbp (+vat) for the unit alone for our cars.


I do have a low mileage unit for sale, pm me if interested.

 

I bought a Quaife ATB LSD is 2011 and paid $1500 for it. I'm not sure what they are selling for now.
