The Scots head into the clash at Hampden aiming to keep the momentum going following a string of positive results and performances under Gordon Strachan.
And Beasley believes United States boss Jurgen Klinsmann will be using the game to assess his players ahead of next summer's World Cup.
The former Rangers player said: "It's important for both teams.
"We have guys who are pushing for World Cup spots and these are games where Jurgen looks at players.
"He wants to see who can handle it and who can't.
"It's very important to us and it's more than a friendly.
"In Scotland, there is a new coach, new ideas and they are trying to make sure they are doing well for the next Euro Championships. Both teams have something to fight for.
"It's not just going to be a friendly, it's going to be a great match."
Beasley was back on familiar territory as the USA squad made use of the facilities at Rangers' Murray Park training complex.
He added: "It feels great to be back here. I got to see some old faces and I'm sure I will see some more.
"I didn't miss the weather, with me being in Mexico, but it's great to be back and I'm very excited about the game on Friday."
The last meeting between the two sides saw Scotland slump to an embarrassing 5-1 defeat in a friendly in Florida in May 2012.
Beasley said: "It will definitely be a different game. There are different players and they are at home.
"Hopefully it will be an exciting game and both teams will be trying for the win."
