    Series 2a Diff Center or Whole Housing?

    Hi, I have a series 2a landrover, I don't have a overdrive and when I'm in top gear it is rev-ing very high. I know my diff is something like 4.7 ratio as a stock and because my rev counter is reading around 4600 on the freeway I'm guessing it's stock.

    I want to know what models can I interchange the whole axle (both Front and Rear) or which models can I get the diff center out of. How would I tell if I have a sailsbury or other kind of diff housing? I have drum brams all round but my front hubs are lockable/freeable which I don't think is standard on a series 2a. It's a 71 year model LWB.

    What kind of cost should I expect to pay at a brakers yard for such items?

    I have a Holden 186 with twin barrel carby that puts out plenty of power but rev-ing is just wasting it's potential and fuel.

    Also, if I have a sailsbury are they all the same centers (like from kingswoods, Fords, Landrovers, etc.)

    Thanks,
    -Bryan.

    The Holden engine is unsuitable with the standard gearing (4.7) because of the problem you note. The diff centres can be swapped with Rangerover ones (3.54)provided you have a Rover rear axle. This is distinguished from the salisbury very simply - the rover diff has the complete diff centre bolted into the axle housing. The salisbury has the diff centre built into the axle housing and has a removable cover plate on the back. Your 2a will almost certainly have had the Rover axle as standard (although salisbury was an option) but many have been changed. If you have a salisbury axle, changing it is more complicated and probably more expensive.

    The alternative is to install an overdrive. Simpler, but probably more expensive than a diff swap.

    I'm pulling the holden out of my landie on the weekend just for this reason. Too many revs at highway speed. Although i'm putting a 2.6L land rover 6 and an overdrive in.

    It doesn;t matter what motor is in it, they will rev the same unless the gearing is somehow changed.

    I'd calculate what rev's you'd be getting with regular 3.54 diffs and looking at the possibility for a change to that
