The Rugged Ridge transfer case lowering kit for 1987–2006 Jeep Wrangler applications is a hard‑plastic spacer engineered to reduce rear‑driveshaft vibration by lowering the transfer case slightly. It installs with a simple bolt‑on procedure and helps correct driveline angles without major modification, providing a practical fix for vibration issues encountered after suspension changes.
