Surely straight-across between-the-radius-arms guards such as that would be detrimental to suspension flex too?

Don't the arms need to move independently? :unsure:

I'll weld one to the front of mine when the diff is out for the LSD and matching 26 spline shafts and HD CVs going in...



I'll weld a plate under the diff too, to protect that bit too...

Mine will see rocks! (I don't drink and drive, so I'll walk to the pub and leave it at home ;) )

Heres mine - attached. 5 mins to put on or remove.

I don't have it on day to day but it's taken a bit of a beating lately.

I can't work out how that strip of metal is supposed to strengthen or protect anything?

It's bolted between the radius arm brackets which are welded to the axle housing and don't move relative to each other. The radius arms can still flex on their bushes as usual.

Attach before going to the pub, remove when you need to go off-road?

It's no surprise it's taken a beating. It must catch on every rock, stump, stick, leaf and cigarette end you drive over!

It's not my design, but I figure it's a 6mm arc of steel plate that's welded onto the front pan of the diff to protect the crown wheel from getting knocked by rocks denting the original (thinner by comparison) axle casing...?

Nah, under articulation one radius arm goes up and one goes down, but it would be hampered by an arm-to-arm guard, even if the bushes can still twist... the arms are effectively bolted together...?

Just how are the arms affected by this guard?

It bolts directly to the inner side of the radius arms mounts. So the arms and bushes are in no way affected by the guard.

So no, the arms are not bolted together.

This is correct this guard will have no effect on the arms

The radius arms need to deflect side to side, "twist" under articulation, with something rigid bolted between them this is obviously hampered...?

Think of one arm going up, and the other arm going down... now think about bolting something in between them, and again imagine their movement under articulation... one up, one down...
