Davies started on the front row with Hooper for the championship decider and followed him for much of the race, taking the lead in the dying stages to win by just 0.242 of a second.
In the dash for the line Hooper slipped to third in what would have been a bitter pill to swallow after being in front for most of the contest.
Steven Ellement, who was also in contention, was fourth, with Glenn Carstairs rounding out the top five.
One of the title fancies Troy Johnson was out on the second lap, limping to the infield.
When of the battles for the lead was brewing with a handful of laps remaining Matt Brown flipped on the back straight in a big way.
The battle for the lead again intensified in the last three laps with nothing between Hooper, Davies and Luke Nardini when Brent Lockwood flipped in turn two.
Hooper set up his front-row start with a win in the B Dash, taking the 10-lapper from Johnson, Cameron McKenzie, Chris Dymock and Brown.
Davies got his front-row start after winning the A Dash from Ellement, Luke Nardini, Trytan Caley and Jamie Nardini.
They both claimed a heat race at the start of the night.
