Keep thinking about this (probably way too much!). On my bus the tie rods are horizontal when it’s on the ground. During cornering and as the body rolls, would this have the effect of creating increasing toe out as the tie rods move in an arc around the pitman arm and effectively shorten - granted it wouldn’t be much. Mid corner and as the body rolls, the outside wheel is ‘loaded’ and increasingly steering away from the corner. On a bus with stock beam & spindles are the tie rods angled down towards the spindle? If so there would be increasing toe in on the outside wheel as the tie rod effectively increases in length. I’m probably over thinking this but just trying to work out the effect of an ARB and reducing the body roll.

Getting a bit technical for me re Ackerman angles etc however, I’ve cut and sleeved a standard front ARB for my 65.

Creative Weedeater 2, dropped spindles, Gaz shocks.

Drives really well and was such a joy to feel the difference in steering when I picked it up from the garage.

Tried fitting the clamps myself but it was a no no. Ended up having to buy a new set of clamps as I ruined the first set trying to fit myself.

Mind you that was on axle stands in a cold garage.

When cutting and sleeving make sure you get the distance between the two ends spot on. I was probably 3-5mm too short, but just about got away with it. Don’t forget you have to fit the small u shaped clamps on the tips for max effectiveness.

I’m probably 1mm away from the central boss on the beam with the sleeve, so don’t go too thick. I had mine done by an engineering shop and professionally welded.

Incidentally, I didn’t know a rear ARB was available ? Anyone have a pic or details ?

There isn't a rear ARB for a split, there there are aftermarket ones for IRS and SA bugs, so there are options but none are easy.

But yes, I remember CE telling me an ARB wasn't necessary on a CE beam as it would make no difference. I wonder if he believed that, or it was just as they don't make one. Those that I've fitted them for have always said it makes a massive improvement and wouldn't remove it.

Might need to edit your post Jim to “wouldn’t” remove it !

I’m IRS on the rear - do you know who does rear IRS ARB ?

Lol...

Sway Away are usually the manufacturers, but they only deal with the trade. So you'd need to do find their part numbers and hunt for a US stockist.

JonnyCJ - thanks for the info. Did you fit a standard ARB (Shortened & sleeved) or was it an HD one?

Standard one. It’s rigid as all hell once shortened and sleeved ! Standard engineering shop can do it for you, but make sure they weld the middle and then grind down before sliding the sleeve over the weld and welding that.

Also crucial that the overall shape is maintained - any rotation of the two ends away from each other will make fitting nearly impossible and if you did get it on it would make handling bobbins.
