Carrick won't talk himself up but his team reckon he'll impress in the top class.
"Jayden will go all the way, we want him to go right to the top," team supporter Greg Brodie said.
Meanwhile, Hayden is in his first season in the 600s, riding Carrick's old bike.
"I'm just trying to improve each race and get better as the season goes on," Hayden said.
"I was close to top 10 at Manfeild so top 10 would be good."
Hayden said he and Carrick have always helped each other out and teaming up would give them a chance to share tips and motivation.
They have also gained sponsorship, with Wanganui Toyota supplying a ute and Display Associates, Dyno Lab, Mischief on Guyton and Tiles UnLtd all backing the team.
The pair were looking forward to home track advantage and said Cemetery Circuit was an even playing field as no one had the chance to practise on the track before raceday.
The pair are treating this series as a build up for nationals at Hampton Downs and Taupo next year.
