Free Rolling Suspension Arms

thingiverse

I use 3/16*3/8 bearings commonly found in RC10T3 front wheel bearings. A spacer behind the arms prevents them from hitting the upper shock mounting arms, allowing the rear end to roll like the front of the Sakura D4 Black Edition. You'll need a spacer in front of and behind the bearing to sandwich it in place. I used old plastic shock bushings that expand when compressed, locking in the bearing. You'll also need tie rod length that allows the upper arms to be horizontal when at rest. I've included links for both customized washers: Inside Washer https://www.thingiverse.com/thing:3812727 Outside Washer https://www.thingiverse.com/thing:3812725 Make sure the arms are facing the correct way, as the holes aren't perfect and one side will be longer or shorter than the other. I'm still learning Fusion360. Thanks for your understanding, and let me know how this works out for you.
