TC/VSC/ABS issue when going around turns

I'm having issues with my traction control engaging randomly while driving, which had led to the ABS also engaging and me losing my brakes. The TC light will usually flash when going around a turn, but it's usually in straight aways that the ABS engages. I recently bought the truck with a 2" spacer lift (I've since learned after buying that I should move to a leveling kit or suspension lift) and 275/55 R20 tires. I've taken to a shop and they have done a zero point cal and replaced the steering rack, but the issue is persisting. In still brand new to truckery so please forgive my lack of knowledge. Any advice on what I could do to fix this issue would be most appreciated. I'm very close to just taking everything back to stock and building back up from there
