Lenny Dykstra’s plan to profit off his troubled past has hit a snag, a new lawsuit reveals.

The former Mets outfielder says in a Manhattan federal court suit that the lending company he agreed to shill for in 2016 — using his bankruptcy as a hook — has reneged on its end of the bargain.

Dykstra now wants the company, Rebound Finance, to stop using his “name, portrait, picture, and life story for any purpose” until a new deal can be hashed out, according to the suit.

Dykstra, nicknamed “Nails” by his fans, joined forces with Rebound Finance in 2016 as its “brand ambassador” and used his own troubled life story — including bankruptcy and prison — to try to sell the debt company to people going through hard times.

While promoting his 2016 memoir “House of Nails,” Dykstra talked up Rebound Finance on “The Howard Stern Show” in between boasts about his sexual conquests.

“Hard work and hustle took me from an underdog to world champion and multimillionaire entrepreneur. But life also knocked me down. I know better than anyone that no matter how much success you’ve had, sometimes good people need a second chance,” the former MLB All-Star said in announcing the October 2016 deal with the company.

The former New York Mets and Philadelphia Phillies outfielder, who served six and a half months in prison for bankruptcy fraud and other crimes, claims that Rebound Finance’s owner, Scott Satov, promised him 25 percent of gross revenues in exchange for his celebrity status.

“Dykstra, however, never received a single payment of the percentage of gross revenues he was owed under the contract,” the lawsuit says.

The revenue deal then turned into a 25 percent equity stake, which then turned into a new deal Dykstra claims he never agreed to after the company was bought by Debt.com, the lawsuit said.

Satov and Howard Dvorkin of Debt.com “continue to profit off of Dykstra’s celebrity, while falsely denying Dykstra’s ownership interests and neglecting to compensate him for the name recognition he continues to bring to the Rebound Finance brand,” the lawsuit says.

Neither Satov nor Dvorkin returned requests for comment.
