Shelton Motorsports is charging into the 2025/2026 Drag Illustrated Series presented by J&A Service with a major new partnership, announcing earlier this week a technical and operational alliance with Killin’ Time Racing (KTR). The collaboration takes effect immediately as the team prepares for this weekend’s Snowbird Outlaw Nationals presented by Motion Raceworks at Bradenton Motorsports Park.
The two-car effort features Stan Shelton and Kevin Rivenbark, who will wheel a pair of supercharged Ford Mustangs in the $50,000-to-win eighth-mile Pro Mod event, which kicks off the three-race Winter Series.
KTR, led by two-time NHRA Pro Mod world champion Steve “Stevie Fast” Jackson, will provide Shelton Motorsports with full-spectrum support both at the track and behind the scenes.
“The Sheltons are heavily invested in our sport and are equally as passionate about drag racing as we are,” Jackson said. “Their entire team gives it their all at every outing, and we feel confident that this partnership will be equally beneficial to both organizations.”
Based in Thomson, Georgia, KTR has become one of the sport’s most respected drag racing solutions companies, offering everything from tuning and diagnostics to complete team guidance. Their philosophy—show up, work hard, and support racers with integrity—aligns directly with the Shelton family’s approach.
For Shelton, the partnership represents a strategic step forward as the team enters the second annual DI Winter Series and later, the 2026 NHRA Pro Mod Series season.
“Team Shelton Motorsports is super excited about our new alliance with Stevie and KTR,” Shelton said. “KTR brings our same passion for hard work, energy, and dedication to racing that our team will look to thrive and prosper on and certainly benefit TSM moving forward.”
The timing of the announcement couldn’t be better. The Snowbird Outlaw Nationals is expected to draw one of the toughest Pro Mod fields of the season, serving as a critical first test for the newly unified effort. The event is the opening round of the Drag Illustrated Winter Series, a three-race championship paying out more than $300,000 in purses and bonuses.
Snowbirds qualifying begins Thursday evening.
