KYB 343164 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G 343164 is a rear suspension shock absorber built to restore original ride control, stability, and steering response. It is a direct OE-style replacement for select Chrysler, Dodge, and Plymouth applications, including Chrysler LeBaron, Dodge Shadow, and Plymouth Sundance rear suspension setups.

KYB Excel-G is the brand’s OE replacement line, produced on KYB assembly lines with OE-quality components and calibrated to return the vehicle to its designed damping characteristics. For drivers servicing older Chrysler and Dodge rear suspension systems, part number 343164 provides a practical replacement focused on control rather than changing the vehicle’s ride feel.

• Lower mount type: E2 (10x41)
• Upper mount type: E2 (10x41)

Product Details

The Excel-G line is engineered to restore the vehicle’s original suspension behavior, making it a solid choice for Chrysler LeBaron rear shock replacement, Dodge Shadow rear shock replacement, and Plymouth Sundance rear shock replacement. KYB 343164 is also listed for additional rear applications across Chrysler, Dodge, and Plymouth models from 1981 through 1995, including Chrysler Dynasty, Imperial, New Yorker, and Town & Country, as well as Dodge Aries, 600, Lancer, and Daytona. This part cross-references Monroe Shocks & Struts 5864 for the same application.

What It Helps Address

• Excessive rear bounce after bumps
• Reduced body control during lane changes and cornering
• Uneven tire contact caused by worn damping
• Loose or unstable rear suspension feel
• Delayed response from aging OE shock absorbers

Installation Notes

Install as a rear suspension shock absorber for the listed Chrysler, Dodge, and Plymouth applications. Follow the manufacturer’s instructions for vehicles that require replacement of the suspension strut and coil spring assembly. Verify mount type, compressed length, extended length, and stroke length before installation. This part is listed for rear position only.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is built on the same KYB OE assembly lines using OE-quality components. The design is calibrated to restore original performance characteristics for the vehicle’s suspension system.
