Front Shock touching Tubular turret

Hey folks

Fitted some new front procomp shocks today. Noticed after a quick test drive one had a slight scrape on it and both sit very close to the front edge of the turret. The scrape seems to be where one of the tubular bits is welded to the ring where you bolt to chassis. I have standard height everything

Is it usual for them to sit forwards or have I got another problem going on somewhere?

Any help appreciated as always.

Like this?
I asked the same question and apparently its usual.

Whats causing that? as it looks terrible.

On mine I had this problem. I think it was caused by my fitting a slightly fatter shock than the Britpart specials that were on before. I filed a tiny bit off the base of the turret where it was fouling. It only needed a couple of millimeters taking off - not enough to weaken it.

Thanks everyone. Looks like I will have to take them off and file them as well. If it wasn't for the aftermarket turrets I don't think there would be an issue.

The axles location will be determined by the radius arms, as that controls and locates that movement.

Different length arms, bent mounting points or different thickness bushes where the arms mount to the chassis affect where the axles sits.

Also the arms move in a radius, so as the axle moves up and down, it will also be moving forwards and backwards.

I can see and agree with that, but from the pic it looks like the axle is 2 inches ish to far forwards.

I think the fat shocks are a red herring and theres more serious issues there.

Im far from a perfectionist but I wouldnt be happy with that at all, in fact my daily motto is, near enough is good enough!

Cheers.
I didnt nitice the angle when stripping it down but all ive done is fit new turrets, bog standard shocks and new bushes in radious arms. Ive measured the bushes and they are almost the same as the rubber ones i took out. As far as i can see the only thing to create this is larger bushes at the chassis end of the radious arm. Also, when the springs are under compression, the damper would move nearer the edge of the turret mount.

It's that precision engineered Solihull suspension geometry. Here's a picture of mine when I did the springs and shocks in the autumn of 2013:



Once again, it looks like the axle is too far forward in relation to the spring seat on the chassis. There's nothing you can adjust, as the axle position is defined by the length of the radius arm, and it's a factory standard chassis that's never been crashed. Obviously if I were building a car from scratch, I wouldn't build it like this. On the occasions when I have constructed suspension components I have measured obsessively, back and forth, up and down, side to side and diagonally. Yet the Land Rover arrangement seems to work, from motorway speeds down to rock crawling, so maybe it's alright after all.

While I cannot prove it, I suspect it is fine. The radius arm doesn't really move beyond the horizontal plane upwards, so with the radius arm almost perpendicular to the ground (as it is in the photo), it will be at is't relative longest, pushing the axle forward most.

As the axle drops, the shock will look more central as the axle will have moved backwards slightly.

One old pic and one slightly newer pic of mine, not very good pics I know.

Newer one but still a few years old now
