The side-on crash on Saturday in Sydney severely hampered Lowndes' weekend, leaving both car and driver badly bruised.
While Dutton says that Lowndes' body has fully recovered over the off-season, the chassis will sit on the sidelines for the time being.
“Craig's going back to his old chassis,” Dutton confirmed on the Red Bull wesbite.
“It (the new chassis) did get bashed around a little bit at Homebush and Bathurst, so that car is currently being put back to pristine condition.
“The car that he was racing since the beginning of 2013, there wasn't ever anything wrong with it, so we're pulling that one out because it's in A1 condition ready to go, so we can spend more time giving it a really good birthday.
“We've decided to go down that route and Craig's more than happy with it because he has had success in that previous chassis.
“Car 1 is staying with the same chassis. It's a proven winner, it just needs a birthday as well, which is happening.”
As previously reported, Lowndes will have a new race engineer for the 2015 campaign, with his partner of eight seasons, Jeromy Moore, set to head overseas.
“We're still deciding the exact structure of who's replacing him (Jeromy), but either way Craig's getting a new race engineer, so that is a massive deal,” said Dutton.
“Jeromy, not only as a race engineer, but designing over the years and as chief designer, has played a massive part in the team's growth and success, so there will be a void that we need to fill.
“I'm hoping it'll be a credit to him and the rest of the team how well we've all worked in unison and shared the knowledge so that the void isn't nearly as big as it could be because we don't keep secrets here.
“Within the team, it's open book – we work together, we collaborate, so therefore our roles and knowledge base overlap enough that it should be much easier to transition.”
