I can't help you as I don't own any 4s rigs, but have to ask; did you try adjusting your steering trim on your transmitter before trying to remove the servo?
 
so this video is the same for the 4s Kraton v4?
As far as I know, the power module is the same in the 3s and 4s trucks. They are about 80% the same trucks. Kraton is a wide BBRC, the OutCast is a wide Granite. I believe the suspention and slipper are the only parts different.
 
How much do you want to spend?

For controler, a basic remote like the DumboRC X6 is $30. A nicer remote like the Spektrum DX5C is about $150. And there are lots more expensive from there...

Servos, look for about 15kg or 200oz/in and 0.15s or better. There are $20 servos on amazon that will do it, or $100 Savox.

You can apply the same process for removing the power module between the 3s and 4s line up.

If you want your steering to be dialed in then follow steps below.
1. New Servo, one mentioned above is fine.
2. New servo saver. Factory will work but what’s recommended and in my experience works better, go with a kimborough 124 hd ss.
3. HR aluminum bellcrank. At a Minimum swap the bellcrank bushings for bearings.
4. HR pivot balls.

As for radio,
Dumborc. Great radio under $35. This will wake up the handling alone.
Radiolink, havnt tried but bridges the price gap between my top choice the flysky gt5.
Edit

This as mentioned above is where I’d start for the K4s.
