The Rancho upper rear control arm bushing for 2007–2017 Jeep Wrangler is a forged‑end replacement that uses D2 polyurethane to improve damping and extend service life. A PTFE liner within the internal bushing enables low‑friction, maintenance‑free operation while firmer inner and softer outer materials reduce noise, vibration and harshness, making it a durable direct replacement for Wrangler JK rear control arms.
