Product Details

KYB Excel-G is the brand’s OE replacement line, built on the same KYB assembly lines used for original equipment production and calibrated to restore factory ride characteristics rather than change them. For rear suspension service on the 1993-1997 Mazda MX-6, 1993-1996 Mazda 626, 1993-1996 Ford Probe, and 1997 Ford Probe, part number 235603 provides a direct-fit strut solution focused on control, braking stability, and lane-change response. This part cross-references Monroe Shocks & Struts (e.g., 71936) for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced cornering stability and body control
• Loose or delayed steering response during lane changes
• Uneven tire contact caused by worn damping
• Suspension noise or vibration related to worn strut components

Installation Notes and Tips

• Fits 1997 Ford Probe, rear, recommended OEM replacement; exc. electronically adjustable suspension; to 7/97
• Fits 1993-1996 Ford Probe, rear, recommended OEM replacement; exc. electronically adjustable suspension
• Fits 1997 Mazda 626, rear, recommended OEM replacement; to 7/97
• Fits 1993-1996 Mazda 626, rear

KYB recommends replacing the strut mount with part number SM5094 and protecting the new strut with KYB strut boot SB101 to help reduce noise, vibration, and contamination. Verify rear suspension configuration and application notes before installation.
