Craig Rodger, 25, was hit by a Porsche as he crossed Wilbraham Road in Chorlton, Manchester, in March 2014.
Mohammed Basit Chaudhry was accused of causing death by dangerous driving but died in Dubai the following year.
Mohammed Omayr and Raheel Rehman, both from Chorlton, were sentenced to two and three years respectively at Manchester Crown Court.
Police said Omayr had been contacted by Mr Chaudhry after the crash.
The men drove in convoy to Brookburn Road, about half a mile away from the scene of the crash, where Rehman set fire to a Porsche Panamera.
Mr Chaudhry was dropped off at his home by Omayr, police said, and, six days later, he left the country. The following month he died in a collision in Dubai.
His identity and death were confirmed when his body was brought back to the UK.
Omayr, 33, of Wilbraham Road, and Rehman, 28, of Lambton Road, both admitted conspiracy to pervert the course of justice at an earlier hearing.
After sentencing, Mr Rodger's family said they had been given "legal closure" but "the grief and heartache for us will go on forever".
They added: "To anyone who thinks they can drive recklessly and dangerously on our roads, this is the result, and to think you can then run and cover up your crime - you cannot and you will always look over your shoulder until you are brought to justice."
Sgt Lee Westhead, of Greater Manchester Police, said Omayr and Rehman were "cowardly and insidious individuals".
"The decisions they made that night are truly abhorrent," he said.
"The unwavering patience and dignity demonstrated by Craig's family throughout this period is utterly amazing."

Berahino, 22, had said he would not play under Albion chairman Jeremy Peace again after the club rejected two deadline-day offers from Tottenham.
But he made his first start since at Villa, poking home a first-half strike.
"It's over now. As a club we move on and he's a very good player," Pulis said after the game.
"This game was made for Saido. He's not played a lot of football and looked tired as the game went on, but he was desperate to play and he has the quality that we want and need.
"Everyone makes mistakes - in a few years' time he will look back on the situation and think he should have done better."
England Under-21s forward Berahino returned to the Baggies squad last week after a three-game absence, coming off the bench in the 0-0 draw with Southampton.

Those detained include players and directors from around 30 clubs from Italy's third and fourth divisions.
More than 70 people are also under investigation in the inquiry led by prosecutors in the southern town of Catanzaro.
Police said that some of those charged had links to mafia organisations.
Catanzaro prosecutors said they had uncovered an alleged network between club presidents, coaches, players, and some management members.
Those arrested are suspected of "conspiracy to commit sporting fraud", ANSA news agency said.
Police said they were studying suspicious results in dozens of matches.
Reports say that the 'Ndrangheta crime syndicate is believed to be behind some of the match-fixing.
The syndicate is a network of clans in Calabria - in the 'toe' of Italy - that dominates the country's cocaine trade.
Local media said that one police officer was also involved in the scandal.
It is not yet clear whether Tuesday's police inquiry is linked to a previous anti-match-fixing operation.
Police had already placed more than 100 people under investigation for suspected match-fixing since 2011.
But prosecutors in the cities of Cremona, Bari and Naples had been focusing on Serie A and B matches.
Two men who helped an alleged hit-and-run killer conceal evidence have been jailed.
