I’m not a fan of either brand you listed. KYB is decent oem shock replacement. For coils maybe try:
1999-2002 Toyota 4Runner Coil Spring (Left, Right, Rear) 48231-35200 | Ourisman Toyota of Richmond Online Parts
They have the spring seat and shock listed in the “also purchased” section.
Also consider the replacing the rear will show how bad the front setup may be… so be prepared to change those out too.
I also know a lot of folks are happy with bilstein setups that stay close to oem ride heights and quality.
