This is a set of optional 10 degree front steering knuckles and caster hubs for the Kyosho Lazer ZX-5 4WD off-road buggy. Included in this package are left and right steering knuckles and left and right 10 degree caster steering caster uprights. These have more caster angle than the stock 7 degree steering uprights, which will give the buggy more corner entry steering and less corner exit steering.
