Charges include fraud against insurance firms, conspiracy to steal vehicles and money laundering, said Gwent Police.
Those charged, from Caerphilly county and Cardiff, are due to appear before Cwmbran magistrates on 10 October.
Gwent Police said it followed a two-year investigation into a "crash for cash" scheme - where accidents are staged to defraud insurance companies.
The force said the inquiry, called Operation Dino,(see ABP News of 29 Oct 2012 and 13 Mch 2012) is into allegations relating to a garage known as both St David's Crash Repair and Easifix, which was based in Pengam, Blackwood.
Det Sgt Andy Cullen, who has been part of the investigative team, said:
"A team of officers and detectives have been investigating this sophisticated 'crash for cash scheme' alongside the Insurance Fraud Bureau for more than two years, and this has led to the arrest and charge of these 86 individuals.
"If you suspect anyone of committing insurance fraud, you can contact the police on 101 or report them directly to the free and confidential IFB Cheatline on 0800 422 0421, or online at www.insurancefraudbureau.org/report."
Gwent Police said the Operation Dino team was established in 2011 using officers from several different departments of the force to specifically investigate suspected "crash for cash" insurance frauds.
