Depends entirely on how demanding you are and what your environment looks like.
If you are expecting an offload monster and buy an AT kit from DIYE, you will be in for a surprise. It won’t meet your expectations and the upgrade path will be very expensive and partly non-existing. A replacement battery pack won’t fix the lack of torque and amp delivery, replacement motors won’t fit the ESC/not ideal (motor mount issue and a specific KV is expected, buy a VESC and they won’t fit the high KV motors, replace motors & esc with proper KV and VESC and the motor mounts will turn out to have incorrect tension (slipping due to increased power), destroy bushings due to your harsh riding and you will find that there are no replacements available. You can now throw away your trucks or DIY parts yourself.
Note that people are replacing bushings for much more expensive trucks every odd month or so.
My tip. Buy their kits if you are a beginner-intermediate rider…and stick with their parts.
Big exception to the above is the TB parts & certain clones.
