Product Details

KYB Excel-G part number 348021 is engineered to restore the Honda Insight’s original suspension feel at the rear axle. The design focuses on control and consistency, helping the vehicle respond as intended during lane changes, braking, and uneven-road driving. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 2010-2014 Honda Insight, rear. The listed dimensions include a compressed length of 15.74 inches, extended length of 23.62 inches, and stroke length of 7.88 inches. Upper mount type is S1 and lower mount type is E2 (10.2 x 40).

What It Helps Address

• Excessive rear bounce or oscillation
• Loose or unsettled handling over bumps
• Reduced braking stability from worn rear damping
• Uneven tire contact caused by weak shock control
• Delayed body response during lane changes and cornering

Installation Notes

Fits 2010-2014 Honda Insight, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount style, compressed and extended length, and rear-position application before installation. Because suspension and electronic safety systems work together, restoring the rear shock to factory-spec behavior helps maintain the vehicle’s intended system performance.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced on the same KYB assembly lines used for original equipment applications. The part is built to OE-style standards for fit, damping control, and durability in normal service.
