The Kyosho OT-31 parts bag contains 10 m3 threaded 5.8mm pivot (or ‘pillow balls’) with a cross head. The single-piece pivot balls are only used on the Lazer ZX-Sport, as the other models use loose balls held in place by a screw.
Alternatives
- 1284 is the same, but contains 8 pieces
- SC-241 is the same, but contains 4 pieces with a hex head rather than cross (allen key needed)
I don’t find the 240 to be the same. They are slightly smaller and the balls will not rotate as freely. Take this into account. - W-0300 is a titanium part with hex head (4 pieces)
