KYB Excel-G Rear Strut for Nissan 240SX

The KYB Excel-G 341099 is a rear suspension strut for select 1989-1994 Nissan 240SX models. Built to restore original ride control, it focuses on stable handling, braking response, and lane-change consistency rather than changing the vehicle’s factory character.

Detailed Description

KYB 341099 is engineered for the rear suspension of the Nissan 240SX and is a direct-fit replacement for drivers looking to return the vehicle to factory-like ride control. The Excel-G design uses a twin-tube, nitrogen gas-charged construction with OE-quality components and calibration matched to the original suspension tuning. With compressed length of 15.08 inches, extended length of 21.18 inches, and 6.1 inches of stroke, this strut is built around the application’s required travel and mounting geometry.

This part cross-references Monroe Shocks & Struts 71233 for the same application. It is also listed as a replacement option for Gabriel G51191. For 1989-1994 Nissan 240SX rear suspension service, 341099 provides a practical OE-style solution when the goal is to restore control, stability, and predictable handling.

What It Helps Address

• Excessive bouncing or reduced damping control
• Loose rear-end feel during cornering or lane changes
• Longer stopping distances caused by worn suspension control
• Uneven tire contact from weakened strut performance
• Noise or vibration related to worn suspension damping

Installation Notes and Tips

Fits 1989-1994 Nissan 240SX, rear, excluding Hicas suspension. Lower mount type is E2(20X42) and upper mount type is S1. KYB recommends replacing strut mounts, part number SM5154, to reduce noise and vibration, and using strut boot SB108 to help protect the new strut from dirt, debris, and salt.

Quality Assurance

KYB is a major OE supplier, and Excel-G is produced on the same KYB assembly lines used for original equipment applications. The design and component selection are intended to return the suspension to factory-calibrated performance for the Nissan 240SX.
