The Kyosho LA-43 parts bag contains the ball ends as used throughout the Kyosho Lazer range.
The newly re-released Kyosho Optima also uses these ball ends, so they are quite widely available and also come coloured in red.
The part number designation is a bit strange as the LA-43RB seem to be the same as the LA-43R. Kyosho normaly indicates alternative colours with the letters after the number. The LA-43B stands for black and is probably the new designation for the regular LA-43 as there is now the red variant available. The designation ‘H’ indicates the ‘hard’ version which offers more resistance to bending while driving, but is a bit more brittle.
Alternatives
The Kyosho 1295 ball ends are a replacement part which come in different colours (yellow and pink).
