Whiteline Rear Upper Inner & Outer Bushing Kit

Stop Rear-End Wander On Your Civic Under Hard Cornering

The factory rubber bushings at the rear upper control arm’s inner and outer mounting points on the Honda Civic soften over time, letting the arm shift under load and causing inconsistent rear-end grip. The Whiteline W63647 replaces both worn rubber bushings with a durable synthetic elastomer kit that locates the control arm precisely, sharpening steering response and stabilizing the rear end through corners.

Key Features

• Replaces both the inner and outer rear upper control arm bushings in one kit

• Locates the rear upper control arm precisely for sharper, more predictable handling
• W63647 is a direct bolt-in replacement using factory mounting hardware
• Backed by Whiteline’s lifetime warranty against manufacturing defects
