It's the splenius capitis.

2I have found that cervical traction is effective in eliminating splenius capitis pain and neck cracking.

Located in the neck (Around the Cervical Vertebrae levels of C1 [Atlas] to C3) Just above the splenius cervicis And it helps support the skull
What are the antagonist of sternocleidomastiod muscle?
It depends on the movement. The prime movers for rotation are the splenius capitis and the sternocleidomastoid.
The sternocleidomastoid muscles are the major muscles that assist you in flexing the neck, along with the longus capitis and a few other small deep muscles of the anterior neck. These flex the neck and head forward or anteriorly. The splenius capitis, semispinalis capitis and longissimus capitis are the major extensor muscles of the neck. These extend the neck upward and backward or posteriorly.

There are many more than two muscles in the neck that perform the action of rotation. Among the primary contributors are the sternocleidomastoid (SCM)-the visible muscle that runs from beneath your ear to the top of your sternum-and splenius cervicis at the base of the rear portion of the skull. Other muscles like your upper traps and levator scapulae also play a role, though not as significant.
