KYB 340063 Suspension Strut - Rear

KYB Excel-G Rear Suspension Strut

The KYB Excel-G rear suspension strut, part number 340063, is built to restore original ride control, stability, and handling for select Honda and Acura applications. It is a direct-fit replacement for drivers who want OE-style damping performance without changing the vehicle’s designed behavior.

What It Helps Address

• Reduced stability during braking and lane changes
• Loose or inconsistent steering response from worn struts

Installation Notes

Fits 2004-2008 Acura TL, rear. Fits 2003-2007 Honda Accord, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5058, to reduce noise and vibration, and a KYB strut boot, part number SB108, to help protect the strut from dirt, debris, and salt.
