2 Kings 8:24 records Jehoram's death and Ahaziah's succession, the very event whose timing 9:29 synchronizes.

2 Kings 8:25 gives a conflicting synchronization (12th year vs 11th) for Ahaziah's reign start, a textual variant.

2 Chronicles 22:1 gives the parallel account of Ahaziah becoming king after his brothers were killed, matching the event in 9:29.

2 Chronicles 22:2 adds Ahaziah's age (42) and one-year reign, complementing the chronological note in 9:29.
