Christian Eckes led the way on the start of overtime but Heim powered quickly to the lead with a push from Kyle Busch Motorsports teammate Chandler Smith.
Eckes appeared ready to take another shot at the lead but a multi-truck wreck erupted on the last-lap, which placed the race under caution and gave Heim the win at World Wide Technology Raceway at Gateway.
It’s the second win of the season for Heim, 19, who is running a partial schedule in Trucks as well as the ARCA Menards Series.

“Yeah, I can’t believe we got the bottom (lane) right there (on the restart), that’s unbelievable,” Heim said. “It was a great push by my teammate Chandler Smith right there. I’ve put so much time and effort into trying to improve my craft.”
Participating in a recent rookie test at the track provided some much-needed confidence entering the weekend, Heim said.
“Anytime we can get the extra seat time, it’s super-important and I feel like we’re getting better every week. Everyone back at the shop has done a phenomenal job.”
Among those involved in the last-lap wreck were Tyler Hill and Carson Hocevar, who exited his No. 42 Truck but was then placed on a stretcher before being taken to the infield care center. He gave a thumbs up signal as he was being placed in the ambulance.
Hoecvar has been transported to a local hospital for further evaluation.
Eckes ended up second, Chandler Smith third, Stewart Friesen fourth and Johnny Sauter rounded out the top-five.
Completing the top-10 were Matt DiBenedetto, Derek Kraus, Ben Rhodes, Zane Smith and Rajah Caruth, who was making his first series start.

Zane Smith powered past Hocevar on the inside to grab the lead on Lap 81.
Kris Wright wrecked in the middle of Turns 3 and 4 on Lap 94 which brought out the sixth caution of the race.
Most of the field elected to pit under the caution but Friesen elected to stay out and inherited the lead. Hocevar was first off pit road but took fuel-only. Caruth was penalized for speeding on pit road and had to restart from the rear of the field.
The race returned to green on Lap 100 with Friesen out front followed by Hocevar and Tanner Gray.
On Lap 101, Zane Smith fell off the pace with what appeared to be a flat right-front tire. Hocevar also lost several position after making contact with Smith.
Hocevar spun off Turn 2 on Lap 108 after contact with Crafton to bring out another caution. Several drivers took the opportunity to pit which allowed Rhodes to inherit the lead.

Nemechek spun coming off in Turn 4 on Lap 54 which collected several other trucks, including Majeski, Jesse Little and Colby Howard, to bring out the caution.
