Series Radius arms

[normbourne]

Hi Guys,

Having experienced "wind up" when driving in low range 4wheel drive, in my series 2A, I was wondering if there would be any advantage in fitting "Radius Arms", obviously they would have to be custom made, (or would they..?)

Does anyone have any experience in such a modification..?

Thanks,
Norm.

Why? It should be able to deal with the windup. Is this for the front or rear? When you say radius arms, are you talking along the lines of anti-wrap bars etc such as:

Transmission windup or spring wrap ?

Anti-tramp/wrap bars can be made up as Slunnie posted, but you'd need to really plan them as it's dead easy to have them restrict your travel.

I don't get it, dosen't the shackle on the chassis end of the cruiser ( in Slunnies image) defeat the purpose of the radius arm !!

I would use a couple of RRC trailing arms & mount them on top of the axle instead of under it.

It remains as a leaf sprung vehicle in every respect with locating the axle and providing the spring action, the addition of the anti-wrap bar only prevents the axle housing from rotating when under load.The reason for the shackle is the action of the spring moves the axle backwards and forwards as it loads and the inflexible anti-wrap bar needs to move with it rather than by binding and working against the leaf springs - ie, the springs and the anti-wrap bar move through different arcs. You could use a radius arm, it's been done that way but you would still need to mount it to the chassis with a shackle.

Ok thanks, of course, now I get it.

When the axle is torqueing the front end of the radius are is moving up/down - not fore - aft .

Hi guys, Sorry about the lack of response to your posts and interest, I've been in a bit of trouble health wise and am only just now getting back to normal.

I hope all's well and you can try popping a wheelie with or without track rods
I have recently acquired a shorty and think I notice the same problem, but I put it down to , new to the car, out of touch with clutch starts, old engine mounts or worn springs
I think I also try to start off at the same rate as modern vehicles, which I am learning to ignore!

Hi Guys,

Still have health probs. But yes slunnie, that's exactly what i,m looking for.

I had intended to modify the front, but I guess it would be politic to fit them on both.....??

Only if you're getting spring wrap on the front as well.

IIRC the old, original leaf sprung Hilux used an arm on the front end to prevent spring wrap as it uses a spring over axle setup, you're less likely to get spring wrap with the spring under.
