His first crew chief job was in 2012 when he crew chiefed the No. 13 Jennifer Jo Cobb Racing team in the Nationwide Series. When Cobb decided to focus on her Truck Series operation that year, the team did not attempt any races for many months and he joined Eddie Sharp Racing as Justin Lofton's crew chief in the No. 6 truck starting at Talladega in October, replacing Daniel Bormann. The following year, he was only crew chief for the team at Daytona before being replaced by Cody Sauls. Eventually, he moved over to Kyle Busch Motorsports as an engineer, and was promoted to crew chief of their No. 54 truck, driven by Christopher Bell, Gray Gaulding, and Matt Tifft, towards the end of the season when Shannon Rursch left the team. KBM shut down the No. 54 truck in 2016, and Troconis went to ThorSport Racing to crew chief Cameron Hayley and the No. 13 truck. After all of their drivers except forMatt Crafton had winless seasons and missed the playoffs in 2016, ThorSport shook up their crew chief lineup the following year and Troconis moved from the No. 13 to the No. 27 of Ben Rhodes. He and Rhodes did qualify for the playoffs and they won the race at Las Vegas that year. Their race-winning truck from that race was nicknamed "marshmellow", as it was one of the trucks that was burned in ThorSport's shop fire in 2015 but rebuilt afterward. The two remained together in 2018, and they won another race at Kentucky, Rhodes' home track, which qualified them for the playoffs for the second straight year. Also that year, Troconis was suspended for one race at Dover due to Rhodes' truck failing post-race inspection at the Daytona race earlier in the year and losing the appeal to the penalty. He was also fined $5,000. Bud Haefele served as the interim crew chief for the team in Troconis' absence. In 2019, Troconis left ThorSport after three years with the team, going to AM Racing as the crew chief for the No. 22 truck driven by Austin Wayne Self.
Personal life
Troconis is the husband of Truck Series driver Jennifer Jo Cobb. Troconis was the crew chief for Cobb and her race team in the Xfinity Series in 2012. They married in 2015. Troconis was instrumental in helping KBM driver Daniel Suárez learn more English when he first came to drive for the team in 2015. Troconis happened to be the engineer for KBM's No. 51 truck that year, which is the truck Suarez drove in his part-time schedule with KBM. The two Mexicans working together came in handy, and Suárez sharpened his English-speaking skills as the season went on with Troconis' help.
