Recommend using V2, has angled screw holes to make sure the weight holder is hanging straight parallel to the wheel. I've also added a V2 steering link mount, which add another stronger option.
This is an addition to AR60 standard Knuckle. By adding you get a stronger knuckle with now front and rear steering link mounting points and weight holder mounting holes.
Remember to invert the knuckle mount horizontally in your slicer to print the other side.
Ideal to run together with a pocket-type wheel with pine car tungsten weight to keep the RC Crawler (Sportsman/Sporty/Shafty, Pro Comps, others) center of gravity extremely low.
