I'm fitting some of the Raceleda (Sierra) uprights to my (Raw era) Striker. The striker has Metro ball joints top and bottom.

The Raceleda uprights will accept the screw in metro ball joint at the top - sorted

The bottom though, has a taper sleeve to accept (I think) a Maxi bottom balljoint. It seems that a Maxi taper spindle is 'fatter' than a metro taper taper spindle by around 1mm (if you see what I mean). My lower Striker wishbone has a threaded socket to accept the metro balljoint but the maxi has a bolt-on flange affair so I can't directly swap without surgery.

I have stumbled across the use of the Princess/Ambassador ball joint which is a screw in type like the metro but MAY be a wider spindle like the Maxi.


Can anyone confirm if the Maxi and Princess spindle diameters are the same?

Ideally I would change the upright inserts to accept the metro joints but they don't seem to exist.

they will be made to sierra dimensions. to get a standard sierra hub to take a maxi ball joint you have to ream it out.

you will be needing this and a bit of elbow grease.

its the 19mm one you need to order.

Thanks for the input but it's not a Sierra dimension taper. Have a look at the picture of the hole above. It's bigger than a Metro dimension ball joint taper and that's the problem. I suspect it was made for Maxi or Transit joints

I can't find a ball joint big enough to fill the hole so making it bigger still won't do me any favours.

There are two sizes of tapper on the EARLY Metros but they were soon altered to one size. Think the one you have will be the latter, common one (like my Fury top). Not sure which one was the fattest but it might be the rare early one and that might fit... If you're feeling lucky.

Yea, trust my luck to have a rare configuration. I bought the uprights way back and have had them sitting on the shelf. Now I've come to install them, they aren't supported (thanks to all at RAW for researching the hubs and bearings/brakes for them by the way)

I've found this MNR response/quote on RHOCAR from a similar query that someone had made about the Sierra uprights:

hi all marc at mnr here
we have not messed up as scott has put it, these uprights fit all cars that run the std config sierra upright with maxi balljoints lower and transit top, the reason people use the maxi lower is greater articluation and the need not to have a long strut top adapter that you guys have for some reason, i havent modellled it in my suspension priogramme but im pretty sure it will give some strange numbers on camber gain, roll centres etc
hope this helps clarify the situation and the reason we are no longer able to supply parts for robin hood cars as there are just too many anomolies to deal with

best regards

From that I take it that the MAXI may have a fatter taper and hopefully so does the Princess which may a screw-in version of the same thing - which I can use to get me out of the shet.

Thanks - I'd appreciate that. I've just measured the Metro ball joint and it's 13.97 at the smallest end of the taper.

Does this diagram of the Maxi ball joint help :

Cheers Tim,

That is a big help. It confirms that the upright I have does take the (larger) maxi ball joint. I just have to hope that the princess joint is the same now.
