Tigers are represented by King and comeback man Kyle Howarth in the Championship Pairs which falls the night before the British Grand Prix at Cardiff.
All 11 clubs are represented and a bumper crowd is expected for one of the biggest events on the domestic calendar.
“I’ve thoroughly enjoyed my season at Sheffield and it would be good to end the season by winning some silverware for the club,” said King.“The Championship this year is the strongest it has been for a long time and the Pairs will be no different - I know how tough it’s going to be.”Howarth is fit to race after making a successful comeback at Peterborough on Tuesday when riding for Premiership Wolves.King said: “We need both Kyle and myself firing right from the off - we’ll certainly give it our best shot.“I didn’t have the best of nights when we rode at Somerset last month but we had a lot of bad luck and managed to pick up a handful of points - hopefully it will all come together on the night.
“It’s a shame we never made the play-offs but perhaps we can win this to take something from the season because as I say I’ve really enjoyed it with Sheffield.”
King is at Cardiff as meeting reserve for the Grand Prix with 40,000 fans expected for the biggest meeting of the year.
“It’s a fantastic occasion and I’m just pleased to be a part of it,” he said. “It would have been nice to have made it as wildcard but it wasn’t to be so I’ve got the next best thing. I’m going to go there to enjoy the occasion.”
