A factory-backed Holden team will remain on the Supercars grid until at least the end of the 2021 championship.
Triple Eight Race Engineering announced on Thursday it had renewed its deal with the manufacturer for two years.
It continues Holden's relationship with Australian touring car racing stretching back to the 1960s and famous names such as Peter Brock and Harry Firth.
Triple Eight has been Holden's sole factory team since 2017 when it ended a 26-year partnership with Walkinshaw Racing.
The team has also secured primary sponsor Red Bull for the same time period despite a difficult 2019 season where Ford rival DJR Team Penske has dominated on the track.
