Title: IRS and Trans upgrade Post by: Peter on April 27, 2010, 11:33:23 am Hey Guys,
was just wondering what to do with my gearbox.... So I will change my S/A box to IRS, and need a diff etc... I ve read about bus flanges on a IRS box that are stronger.. So are the Diff splided shafts also different to accept the bus flanges? I would like to know what parts to buy to strengthen the drivetrain... I would like the to keep the axles and CV's stock for now, but reenforce the box allready if its possible? was thinking about a quaife too...

I donīt know if superdiffs with the bigger type 2 splines are available (Quaife diffs are) but another option would be to use the flanges from a 181 (trekker/thing) which are bigger (100mm in diameter) but fit on the bugīs shafts/splines. This is what I used when the car still had IRS. Bye, Tobi Title: Re: IRS and Trans upgrade Post by: Peter on April 27, 2010, 19:44:05 pm Hey thanks tobi,
which axles did you have to use? Title: Re: IRS and Trans upgrade Post by: Tobi/DFL on April 28, 2010, 08:52:34 am Hi Peter,
I used stock beetle axles which were modified on a lathe to fit the wider Bus CV joints. Bye, Tobi Title: Re: IRS and Trans upgrade Post by: Peter on May 28, 2010, 20:35:47 pm hey guys,
I yesterday bought an LSD from a former autocrosser and trans builder, he told me its a ZF LSD for a beetle, but after some searching on the net, I couldnt find the same as the one I have, so does anybody know what this is? Cheers, Peter Title: Re: IRS and Trans upgrade Post by: Bruce on May 29, 2010, 06:56:29 am It might be a real early ZF.
Does it have any numbers engraved on it? You're looking for a part number starting with 4061 00x xxx Can you post better pics? |
