The Olympic ice dance silver medallists were in red-hot form in Kent, Washington and were not going to allow their figure skating Grand Prix dominance to be stopped.
After scoring 71.39 in the short dance to lead Canadian's Kaitlyn Weaver and Andrew Poje by nearly six points, Davis and White produced the best free dance to comfortably take the title.
The Americans were awarded 104.89 to finish with an overall total of 176.28 more than 16 points ahead of Ekaterina Bobrova and Dmitri Soloviev who shot up to second.
The Russian duo were awarded 97.04 for their free dance and with Weaver and Poje scoring 91.53 they moved into second with 159.95 points overall, the Canadians finishing on 157.32.
There was no doubting the winners but Davis, who has won the past three Grand Prix Finals with White, was not completely overjoyed at their performance.
"We had a couple little technical glitches here and there," said Davis. "We're definitely looking to getting our technical scores much higher. Overall, it was a good start to the season."
Meanwhile compatriot Ashley Wagner successfully battled a case of the jitters to win the ladies' title on her first ever appearance at Skate America.
The 21-year-old was in first place after the short program, her score of 60.61 giving her a slender lead over Russia's Adelina Sotnikova, who recorded 58.93.
And, while she was adamant she could perform well enough in the free skate to win, Wagner had her doubts although she hardly needed to worry.
The American wowed her home crowd to produce the best score and take the ladies' title, her free skate effort of 127.76 giving her 188.37 overall.
Team-mate Christina Gao jumped from third to second overall after recording 117.62 in the free skate for a total of 174.25 as a fall during a triple flip cost Sotnikova dear.
She dropped to third with an overall total of 168.96 as Four Continents champion Wagner breathed a sigh of relief at starting her international season with a win.
"After the short program, I definitely felt it was plausible to win the whole event," said Wagner. "It was kind of a good end, because I started worrying about it a little bit.
"But I'm happy I was able to keep my nerves under control and accomplish what I wanted to accomplish."
