Planning for a new Frame

Several taco owners suggested I replace the front and rear shocks and front spring coils while my 2006 trd 4wd access cab is torn apart for a new frame.

Should I stay with factory parts or look at a third party? I do not want to raise the height. Just keep it at the same level.

Also my rear springs were replaced by the recall.

Any suggestions? Looking for a kit that I can pass to the dealer once year down begins.

I still have four months before work begins. Thanks!
