I think you should try it.
We been using it with no problem even for rear suspension ( with 4.5 - 5 deg camber), means only 3/4 (threaded part) part is threaded to arm.
Just once i ever seen it popes out from the fc blocks(in front) after hard slamming in brick wall, but its still hold up well in the both arms.
