Both teams went into the game unbeaten after four wins from their four respective matches but the Kings were the dominant force in the contest rushing into a 24-0 half-time lead to knock the stuffing out of the Griffons.
Flyhalf George Whitehead was the star of the show for the Kings as he contributed 19 points courtesy of a try, four conversions and two penalties.
Both teams had been locked on 19 log points before the match but the Kings walked away with a full haul of five points, after scoring a bonus-point try, while the Griffons were left empty-handed.
The Kings ran in four tries as they raced to a 34-0 lead in the second half with the Griffons only managing to grab two consolation tries to add some late gloss to the final score-line.
Whitehead got the scoring underway in warm and sunny conditions with a ninth minute penalty before the Kings blew the Griffons away with three tries in the space of 12 minutes.
Left wing Marcello Sampson began the charge when he scooted over for a try in the 19th minute before flank Thabo Mamojelo barged his way over for another converted try.
Whitehead, who missed just one of his seven kicks at goal, then went over between the posts before converting his own try to leave the Griffons starting down the barrel at 24-0 down.
Whitehead began the second-half scoring with a penalty before the Kings wrapped up the bonus-point try, in the 51st minute, when inside centre Tiger Mangweni was on hand to dot down.
The Griffons may have been trailing by 34 points but they had not won four games on the trot by not possessing some fighting spirit which they showed through tries to eighthman Nicky Steyn and flank Francois Uys but it was too little too late for the hosts.
