KYB 343130 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber 343130

KYB Excel-G part number 343130 is a rear suspension shock absorber built to restore original ride control, stability, and handling on a wide range of classic domestic vehicles. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components.

The Excel-G line is KYB’s OEA-style replacement series, focused on returning the vehicle to its designed damping characteristics rather than changing the ride feel. This makes 343130 a practical choice for classic Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac rear suspension service.

Detailed Description

KYB Excel-G 343130 is engineered for rear suspension applications where restoring factory-style ride control matters. The twin-tube, nitrogen gas-charged design uses OE-quality components and calibrated damping to help the vehicle respond the way it was originally tuned to respond. For owners servicing a Chevrolet Impala rear shock absorber, Buick Roadmaster rear shock absorber, or Cadillac Fleetwood rear shock absorber application, this part number provides a direct OE-style replacement approach.

This part cross-references Monroe Shocks & Struts 5955 and Gabriel 69724 for the same application. The KYB Excel-G line is built on the same KYB OE assembly lines used for original equipment supply, which is why it is commonly selected for rear suspension refreshes on 1958-1996 Chevrolet Impala, 1992-1996 Buick Roadmaster, and 1993-1996 Cadillac Fleetwood applications.

What It Helps Address

• Excessive rear bounce after bumps
• Loose or unsettled handling in lane changes
• Reduced tire contact from worn damping
• Oil seepage or gas loss from aging shock absorbers
• Unstable body motion during braking and cornering

Installation Notes and Tips

• Compatible With rear-position applications only; verify the exact year, make, and model before ordering.
• Some listed vehicles require replacement of the suspension strut and coil spring assembly according to the manufacturer’s instructions.
• Several fitments exclude electronic suspension, limousine, or air suspension configurations; confirm the vehicle’s suspension package before installation.
• Measure the existing unit and compare compressed length, extended length, and mount types before service.
• Professional installation is recommended for classic rear suspension applications where spring and strut assembly procedures apply.
