The only changes come on the bench where front rowers Pat MacArthur and Ryan Grant are selected ahead of internationalists Dougie Hall and Kevin Tkachuk respectively.
Further back, Aly Muldowney comes in for Ryan Wilson whilst Rob Dewey returns from a hand injury to take the place of Peter Horne.
Glasgow head coach Sean Lineen said: "I've been really pleased with the attitude of the players and training this week has been outstanding. The players know the wins will come, we just need to keep pushing each other along and keep believing.
"The players have been doing a lot of good things in the games we've played so far, he continued. "It would be difficult if we couldn't pinpoint what wasn't going up to speed.
"We can't fault the players' effort at all, its just decisions and some skills at key times just not coming off.
"It's a very young forward pack. We're making errors and we're getting punished for them, and you'd expect that. But as long as we're learning, that's the key.
"I'm expecting a really physical affair. We've had a bit of good fortune over there in the last couple of years but they've recruited well and have started the campaign well.
"Ravenhill is a great place to play, a really good atmosphere. It can be a bit like Glasgow so it's something that we're pretty used too.
"But Ulster have really stepped up in terms of their physicality and their ambition and how they're playing the game."
