KYB 363012 Suspension Strut Cartridge - Front

KYB Excel-G Suspension Strut Cartridge

The KYB Excel-G 363012 is a suspension strut cartridge built to restore original ride control, stability, and steering response. It is a nitrogen gas-charged, twin-tube replacement that uses OE-quality components and OE-style calibration for drivers who want factory-like handling.

For vehicles such as the Honda Civic and Toyota Corolla, this KYB Excel-G strut cartridge helps return the suspension to the control level the vehicle was designed to deliver. The 363012 part number is also a common reference point for technicians comparing OE-style replacement options.

Product Details

Excel-G is KYB’s OE-style product line for drivers who want a direct replacement that preserves original suspension behavior rather than changing it. KYB builds this cartridge on the same assembly lines used for OE supply, using the same quality standards found in its original equipment programs. The nitrogen gas-charged twin-tube design, OE-calibrated damping, and precision sealing work together to maintain consistent ride control under everyday driving conditions. This part cross-references Monroe Shocks & Struts (e.g., 73934) for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Loose or delayed steering response
• Reduced body control during lane changes
• Uneven tire contact caused by worn damping
• Suspension noise or fluid leakage from a worn cartridge

Installation Notes and Tips

Verify the vehicle application before installation and match the cartridge dimensions to the original unit. This cartridge has a compressed length of 16.85, an extended length of 23.15, a stroke length of 16.34, and a 14X1.50 upper mount type. KYB recommends using a strut boot, part number SB101, to help protect the new strut from dirt, debris, and road salt. For Honda Civic and Toyota Corolla service work, confirm the suspension layout and inspect related wear items before reassembly.

Quality Assurance

KYB is a major OE supplier, and Excel-G is classified as an Original Equipment for the Aftermarket replacement line. The 363012 is engineered to restore original performance characteristics using OE-quality components and factory-style calibration.
