KYB 349210 Shock Absorber - Rear

KYB Excel-G Rear Shock for Scion tC

The KYB Excel-G 349210 is a rear suspension shock absorber engineered to restore original ride control, stability, and handling on select Scion tC models. Built on KYB OE assembly lines with OE-quality components, it is calibrated to return the vehicle to its designed damping performance rather than alter it.

Compatible with 2011-2016 Scion tC, rear, this Excel-G shock is a direct-fit OE-style replacement for drivers addressing worn rear damping on the Scion tC. The 349210 part number is also a common reference point when comparing replacement options for this application.

Key Features

• Nitrogen gas-charged, twin-tube shock absorber design
• OE-quality construction made on KYB assembly lines
• Vehicle-specific damping valves manage tire contact, steering response, and body motion
• Triple-lip fluid seal helps reduce oil and gas leakage
• Strong strut body and bracket design helps minimize flex and maintain alignment
• Rear application for 2011-2016 Scion tC
• Part number: 349210

Excel-G Product Line Details

KYB Excel-G is the brand’s original-equipment-aftermarket line focused on restoring factory ride characteristics. For the Scion tC, that means controlled rear suspension response, stable lane changes, and consistent braking behavior that aligns with the vehicle’s original tuning. The 349210 shock uses KYB’s OE-style calibration and component standards to match the intended suspension feel.

What This Shock Absorber Helps Address

• Excessive bouncing or oscillation from worn rear shocks
• Reduced stability during lane changes and cornering
• Uneven tire contact caused by weak damping
• Slower steering response and less predictable handling
• Suspension noise or fluid leakage associated with aging shock absorbers

Installation Notes and Tips

Fits 2011-2016 Scion tC, rear. Verify mount style and dimensions before installation: compressed length 14.92 in., extended length 22.4 in., stroke length 7.48 in., lower mount E2 (12x60), upper mount S1 (12 mm). Additional components may be required depending on vehicle condition and service procedure. Inspect related suspension parts, fasteners, and alignment settings during replacement.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and Excel-G is produced using the same manufacturing approach and OE-quality components used in KYB original equipment programs. The design is intended to restore original suspension performance on the Scion tC while supporting proper operation of braking and electronic safety systems that depend on suspension control.
