I'm looking at getting a diff rebuilt (IRS VP Calais), i got 3.45 gears and i'm going to get a 4WD systems Lokka, and was wondering, if i bring a diff in that i have pulled apart + the gears and the lokka, what price would i be looking at to get a rebuild kit supplied (new seals and bearings) and the diff assembled?

And do you open on weekends?

[vn calais manual]

so you dont do 4.11 gears for a vn? i was after option 2 with 4.11 gears. also do you fit? would much all up would that come to, drive in old diff drive out new diff.

[immortality]

The prices lised are the fitted prices, drive in drive out, just depends on LSD condition etc...

Yes 4.11's are available

Only new gears sets used, unless the customer suppliees a secondhand gears set to be installed.

[vn calais manual]

G'day mate, whats the general process of running in a newly rebuilt diff involve?

What the manufactors of the gear sets recommend is 500km of no excessive hard acceleration.

With the LSD no donuts at all, also guys doing burnouts when turning out of a street corner will damage a LSD with ease.

I personally dont beleive in running a differential in, as how do u say no hard acceleration and compare what is hard acceleration on eg your vehicle compaired to mine for eg......WOT on yours would be 1/8 to 1/4 throttle on mine see what im saying.

Every car that gears a diff gear ratio change, i guarentee that they give the car hell for days, as evidence is all over the road out the front of the workshop....as its a massive difference over the car a diff ratio change achieves.

I for one have never had a differential failure to not running them in correctly.

U dont see V8 supercars doing 500km's to run a diff and gearbox in.

I hope this helps

Have you done many diff ratio changes on the Alloytechs yet? I'm looking at changing the standard diff in a 5spd auto 05 SV6 to 3.46's. Also wondering if you'll be able to tune the SV6 at any stage? (It's a long drive to Sydney ) Any help or ideas on what option I would need to take would be greatly appreciated
