Product Details

KYB Excel-G is KYB’s OEA-style replacement line, built to return the suspension to its original operating characteristics rather than change them. For the Nissan 300ZX, part number 365056 is a front suspension strut cartridge with a compressed length of 15.43 inches, extended length of 21.97 inches, and stroke length of 14.29 inches. The upper mount type is 14X1.50. This part cross-references Monroe Shocks & Struts 73229 for the same application.

Compatible With 1984-1989 Nissan 300ZX, front. Notes: recommended OEM replacement; except adjustable suspension; to convert from electronic suspension, see paper catalog appendix C; Excel-G. The KYB 365056 is also listed as a front replacement option for Nissan 300ZX models in this range, and it is referenced by the part number 365056 for ordering and catalog lookup.

What This Strut Cartridge Helps Address

• Excessive bounce or reduced damping control
• Loose steering feel or delayed lane-change response
• Body movement during braking, cornering, or uneven-road driving
• Suspension performance loss from worn OE strut components
• Oil or gas leakage from aging strut seals

Installation Notes

Verify front fitment and suspension configuration before installation. This cartridge does not include a dust cover, internal rebound spring, or B-stop. KYB recommends replacing strut mounts at the same time to reduce noise and vibration; KYB SM5097 is listed for this application. A KYB strut boot, part number SB104, helps protect the new strut from dirt, debris, and salt.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers and builds Excel-G on the same OE assembly lines using OE-quality components. The 365056 is calibrated to restore original suspension performance for the Nissan 300ZX platform while supporting proper operation of related vehicle systems that depend on suspension, brakes, and tire contact.
