How can I stop the motor6d's physics from applying?

When I cloned this arm, this is what it looks like.

Clone Script:

local leftArm = ReplicatedStorage.Assets.Stands.StarPlatinum.LeftArm:Clone()
leftArm.PrimaryPart.CFrame = StarPlatinum.HumanoidRootPart.CFrame * CFrame.new(0,0,0)
leftArm.Parent = StarPlatinum

Disable Motor6D’s:

But I want it to look like this.

How can I stop this?
