KYB 365025 Suspension Strut Cartridge - Front

KYB Excel-G Front Suspension Strut Cartridge

The KYB Excel-G 365025 is a front suspension strut cartridge engineered to restore original ride control, steering response, and handling balance. It is a direct OE-style replacement for the 1988-1993 Pontiac LeMans front suspension and is built to match the vehicle’s designed damping characteristics.

As part of the KYB Excel-G line, this cartridge is made on KYB OE assembly lines using OE-quality components and calibrated to return the suspension to factory performance rather than alter it. For drivers servicing a Pontiac LeMans front strut, 365025 provides a practical replacement option for restoring control and stability.

• Strong strut body and bracket design helps minimize flex and maintain alignment
• Electronic safety systems rely on suspension performance staying within manufacturer specifications
• Recommended KYB strut mount: SM5278
• Recommended KYB strut boot: SB101

Detailed Description

KYB Excel-G 365025 is a suspension strut cartridge for the front of the 1988-1993 Pontiac LeMans. It uses a nitrogen gas-charged twin-tube design with a compressed length of 14.06 inches, extended length of 19.76 inches, and stroke length of 13.62 inches. The upper mount type is 12X1.25. This part cross-references Monroe Shocks & Struts 73405 for the same application.

The Excel-G line is built to restore OE ride characteristics, making it a strong choice when replacing a worn front strut on a Pontiac LeMans. KYB’s OE manufacturing background and application-specific damping calibration help return predictable braking stability, lane-change response, and overall suspension control.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering response during lane changes
• Uneven tire contact from worn damping control
• Noise or vibration from aging strut components
• Loss of stability during braking and cornering

Installation Notes and Tips

Compatible With 1988-1993 Pontiac LeMans, front. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. For reduced noise and vibration, KYB recommends new strut mounts, part number SM5278, and a KYB strut boot, part number SB101. Verify all mounting dimensions and hardware requirements before installation.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and the Excel-G line is produced on the same assembly lines used for OE applications. The design focuses on restoring original suspension performance and maintaining the vehicle’s intended control characteristics.
