"We’re delighted Truck Assist has extended its partnership with Supercars and will be this year’s naming rights partner of the Winton SuperSprint," Supercars General Manager – Commercial, Jamie Black said.
"In 2019 Supercars continues to provide significant exposure for its partners and to have an industry leader on board is great news for our sport."
Long-time Holden Racing Team chief Jeff Grech shifted from a role running Supercars outfit Team 18 to oversee Winton during the 2018/19 off-season.
"Winton Raceway is excited to have Truck Assist as this year’s naming rights sponsor for the Supercar Winton SuperSprint round," the venue's operations manager said.
"Our camping and ticket sales are well above last year’s round and with introduction of the Ford Mustang, spectators are sure to see great racing from our vision friendly circuit."
Rick Kelly and Fabian Coulthard split the victories at Winton in 2018.
