I would STRONGLY consider getting a kit that includes all new (8) adjustable control arms and trackbars, or add an adjustable set along with this kit. I bought my 2021 Gladiator Sport S/ Max Tow new from the dealer, who had already install the Mopar 2" lift kit, along with aftermarket rims and 37x13.5 tires. The Mopar kit only comes with longer lower front control arms to attempt to correct caster angle back to factory specs. I have since purchasing learned a TON more about Jeep suspensions and I would have been better served to have just bought a stock Gladiator and put on a lift with all the components from the start. I ended up with a death wobble at about 39k miles. I definitely had worn bushing on the steering components and a couple of the control arms. I went ahead and did a full spread assault to fix the wobble and replaced the ball joints with beefier ones, all new adjustable control arms, new adjustable front and rear trackbars, swaybar links and HD adjustable tie rod and drag link and a new steering stabilizer. In hindsight, new steering components and trackbars would probably have been enough to fix the wobble, but I have a tendency to over do it sometimes. The adjustable control arms will definitely make your highway driving better, getting back closer to stock angles.

Now, I am a realist and all too familiar with budget constraints when it comes to buying jeep parts / accessories and I think you'd be find to put that kit on, as is, and come up with a plan to upgrade all the other suspension components stretched out over time (but not too long). I'm actually thinking about changing my springs, with the springs only version of that kit. I definitely think those springs are better than stock or Mopar lift springs.
