Will this bolt directly into my existing suspension without any bracket modifications?

Yes. This shock mounts at factory rocker points with no drilling or bracket work needed. Unbolt the old unit and bolt this one in its place.

Do I need to replace both rear shocks at the same time?

It's recommended. Replacing shocks in pairs keeps suspension balance and handling consistent side-to-side. A single worn shock can cause uneven braking and drift.

What tools do I need to install this myself?

Basic hand tools — socket set, wrench, and jack. Support the vehicle safely on jack stands and disconnect the shock from top and bottom mounting points. Installation typically takes under an hour per side.
