Is anyone aware of any front arms that increase flex on an 80 series?

I am hoping to get a bit more flex upfront from my 80 series land cruiser and I am looking for some aftermarket arms that will allow this. Does anyone have any suggestions?

Superior engineering are the best when it comes to this kind of stuff. However, I am not sure how easily you can get their products in the US
