Detailed Description

KYB Excel-G 341457 is engineered to restore the original suspension behavior of the Scion tC rear suspension. It uses OE-calibrated damping to help bring back predictable ride control, lane-change response, and braking stability without changing the vehicle’s factory tuning. The strut body measures 11.14 inches compressed and 13.18 inches extended, with 2.04 inches of stroke for the specified rear application.

This part cross-references Monroe Shocks & Struts 72400 for the same application. If you are replacing a worn rear suspension strut on a 2005-2010 Scion tC, 341457 is built for factory-style performance restoration and consistent handling feel.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced braking stability from worn suspension damping
• Loose or delayed handling response in the rear suspension
• Uneven tire contact caused by weak strut control
• Noise or vibration associated with worn strut components

Installation Notes

Fits 2005-2010 Scion tC, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5382, to reduce noise and vibration. A KYB strut boot, part number SB108, can help protect the new strut from dirt, debris, and salt.

Upper mount type is 12x1.25 and lower mount type is E2 (14.2x55). Confirm all mounting points and suspension condition before installation, and inspect related rear suspension components for wear.

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 design uses OE-quality components and factory-style calibration to restore designed performance for the Scion tC rear suspension.
