It is front short arm only for Yokomo YD2 Chassis Series

To complete the assembly you need additional item :

1. Mini Ball Bearings 3x6x2.6 @4 for each arm end (see picture ex2)
2. M3 Bolt 40 mm or more @2
3. M3 Nut/Locknut @2

For the rod to the suspension block I make my own 3 mm aluminium rod and not using the yd2 stock rod, it doesn't fit the 3x6x2,6 bearing although the stock yokomo YD-2 arm rod for what I know is 3mm.

Printing Duration about 45 minute, no need brim, skirt is suffice, i use 100% infill

The supporting block is easily remove after printing done
