Lickliter, who opened with back-to-back rounds of 10-under 62, cruised through the final four rounds of the six-day marathon. He completed the event at 29-under-par 403.
Brett Rumford took second at minus-25 after shooting 70 in the final round. Chris Stroud was third at 23-under-par 409, while Jin Park was fourth at minus-22.
Players rotated for three rounds apiece on the Panther Lake and Crooked Cat courses this week.
Lickliter ended on Crooked Cat with a very simple round. He birdied the par-4 third and parred the other 17 holes.
'I was rolling the ball really well,' stated Lickliter. 'I had a lesson from Bob Toski and a lesson from Vijay Singh and those two together really put me in a good place.'
Over the first two rounds, he posted 19 birdies, one eagle and one bogey to gain a comfortable lead.
'I was just trying to make as many birdies as I could (the first two days),' said Lickliter, who spoke to the media Monday for the first time all week. 'That one bogey (in the second round) was irritating, but the 21 other were just fine.'
Jason Allred took fifth at 21-under-par 411, while Tag Ridings and Yong-Eun Yang were one shot further back.
The following 19 players, in order of score, also gained their PGA Tour cards for 2008 - Todd Demsey, Brad Adamonis, Travis Perkins, Cody Freeman, Kent Jones, Parker McLachlin, Kenneth Ferrie, Dustin Johnson, Kevin Streelman, Duffy Waldorf, Tim Wilkinson, Jim McGovern, Carlos Franco, Tommy Gainey, Richard S. Johnson, John Merrick, Alejandro Canizares, Bob Sowards and David Lutterus.
'Now I know what those marathoners have to do,' joked Waldorf, who will return to the PGA TOUR for his 22nd season next year after shooting 16 under over the final three rounds. 'I think everything hurts a little bit. It's exciting, but it was a long day and a lot of hard work.'
The players who finished 27th through 79th gained full Nationwide Tour exemptions for 2008.
The remaining players in the 166-man field received conditional status on the Nationwide Tour next year.
