My brother built his own radius arm setup on his Cherokee and it did not work well. He ended up removing one of the upper arms to get it to articulate better. It's awesome in the Dunes up in Michigan where he lives but doesn't work so well on the type of trails we run down here. The front end also tends to lift when climbing which is not helpful. It's not horrible but not my first or even second choice.

My suggestion for a 3 link was because if you have a drag link, when the suspension is cycled the drag link articulates thorugh and arc pushing and pulling on the steering knuckle which would cause some bump steer. If driving on the street, I would want to avoid that. By using a trac bar set up in the same plane as the drag link, the axle is forced side to side when articulating keeping the drag link from pushing or pulling on the knuckle. Since this is an offroad only vehicle, or if one was running full hydraulic steering, I'd go double triangulated 4 link if possible.
