KYB 343147 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

KYB Excel-G 343147 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a direct-fit OE-style replacement for classic applications such as the Chevrolet Chevette, Pontiac Acadian, Pontiac T1000, and Toyota Corolla rear suspension.

The Excel-G line is calibrated to return the vehicle to its designed damping characteristics rather than change the ride feel. For shoppers searching for a rear shock absorber for 1975-1979 Toyota Corolla, 1976-1987 Chevrolet Chevette, or 1981-1987 Pontiac T1000, KYB 343147 is a fitment-specific option.

Product Line Details

Excel-G is KYB’s OE-style replacement line for drivers who want factory-like suspension behavior. KYB builds this series on the same assembly lines used for OE supply, using OE-quality components and damping calibration aimed at restoring original performance. Part number 343147 follows that approach for rear suspension service on select Chevrolet, Pontiac, and Toyota models.

Detailed Description

KYB 343147 is a rear suspension shock absorber engineered for classic vehicles that need predictable damping and stable road control. It is designed for applications including 1976-1987 Chevrolet Chevette rear, 1976-1987 Pontiac Acadian rear, 1981-1987 Pontiac T1000 rear, and multiple Toyota Corona and Corolla rear fitments. This part cross-references Monroe Shocks & Struts 5818 for the same application.

As an Excel-G unit, this shock uses a twin-tube, nitrogen gas-charged design with in-house damping valves tuned to help maintain tire contact, braking stability, lane-change response, and body control. The construction also supports electronic safety systems by helping the suspension operate as the vehicle manufacturer intended. If you are replacing a worn rear shock on a Toyota Corolla, Toyota Corona, or Chevrolet Chevette, KYB 343147 provides an OE-style service solution.

What It Helps Address

• Excessive rear bounce after bumps
• Loose or unstable handling in turns
• Longer stopping feel caused by worn damping
• Poor tire contact and uneven body motion
• Leakage from an aging rear shock absorber

Installation Notes and Tips

• Follow the manufacturer’s instructions for suspension strut and coil spring assembly where required.
• Verify rear-position fitment before ordering; this part is for rear applications only.
• Inspect related suspension components such as springs, mounts, and bushings during replacement.
• Confirm the vehicle’s year and model carefully, especially on Toyota Corona applications with different production dates.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced with OE-quality components and OE-style calibration. The design includes a triple-lip fluid seal and a robust body structure to support consistent suspension performance in daily service.
