RRC Radius arm issue...

I know its not a defender, but some of these components are the same, so I was hoping that somebody might be able to point me in the right direction...


I installed what I was told are 3* corrected radius arms on a Range Rover with 3" lift. I noticed some vibrations and noises, so I decided to investigate ( and seal the swivel balls while I was at it...) anyways, after removing the tires I noticed the front axle was being pushed too far forward, to the point that the springs were not sitting right anymore.







You can see the gap on the top of the spring here...



Are the radius arms over correcting the caster? did I get 6* instead of 3?


Thank you for your help...

Those look super corrected for 3 degrees...though it could be the angle. Here are my 3 degree arms(also by RTE)

I too was thinking they look like 6* arms. What springs are you running?

Brett nailed it. Those arms are definitely not 3 inch arms. They look like arms meant for a 6 inch lift or more. Huge offset.

Back to your question about the axle being moved forward:

My RTE arms are also slightly longer than stock, which moves the front axle forward slightly, causing the springs to lean a bit like yours. Seems like a common thing for RTE to do. However, the distance that your arms have moved forward are at least an inch further forward than mine.

Some say that it's related to the amount of lift that a person has on their truck, but I'm not sure I buy that completely.

I think RTE will take those in for cores and give you the correct sized arms at a discount.

It's not the cheapest alternative, but it is an alternative. Shame someone sold these things to you saying that they were a 3 inch lift.

As you push the axle down with lift springs it swings towards the back of the truck. The cranked radius arms are lengthened to account for this and keep the axle centered with the lift.

Of course it is. That is the reason they make them. Brett can explain it to you.

3 degree usually work up to 3" lifts
6 degree are for 3+ lifts.

IF you are running like a 6" lift then you are on your own!
