The 29-year-old has been absent with a calf injury since the autumn Tests and his inclusion is a welcome sight for the Murrayfield side ahead of the crucial European Cup fixture.
Edinburgh are bottom of Pool Six and trail leaders Munster by six points with three games left.
Ford packs down between props Wicus Blaauw an d Willem Nel, and takes on the captaincy from scrum-half Greig Laidlaw, who has been replaced by summer signing Grayson Hart.
Gunners boss Alan Solomons said: "It's great to have Ross back.
"He's a very good player of international class. He's a big strong man and comes in as part of good front-row. It will be interesting to see how they go.
"It's been difficult for Grayson Hart who would have played earlier in the season were it not for injury, after which Sean Kennedy and Sam Hidalgo-Clyne stepped up and did very well. He's had to keep working hard and wait for this chance.
"It's a similar story with Wicus Blaauw who has put in a lot of extra hours through the recent break and I think he is now ready to start at this level.
"He has proved in the past what he is capable of. He was a very good Super Rugby player for the Stormers and I think he's ready for it.
"They're both champing at the bit to get this opportunity."
Solomons has also opted to reintroduced Roddy Grant and Argentina international Tomas Leonardi at flanker, while Joaquin Dominguez steps into midfield in place of centre Nick De Luca.
Solomons added: "We performed poorly in the first-half against Gloucester last weekend, we were flat.
"When you get a performance like that you have to make a change and the guys coming in are straining at the leash to play.
"I'm looking forward to seeing them get out there and put in an improved performance on last week."
