When replacing suspension components on a Mitsubishi Montero, using the correct spring insulator helps maintain proper spring contact and reduces metal-to-metal noise. The KYB SM5345 is a practical choice for restoring the original feel of the front upper suspension on 2001-2006 Mitsubishi Montero models.

What It Helps Fix

• Squeaks from worn spring seat material
• Rattles caused by hardened insulators
• Vibration noise transferred through the front suspension
• Reduced ride comfort from deteriorated spring isolation
• Noise issues at the front upper spring mounting point

Installation Notes and Tips

Fits 2001-2006 Mitsubishi Montero, front upper. Verify the suspension position and compare the original insulator before installation to confirm the correct application. Inspect related mount components, springs, and surrounding hardware for wear while servicing the front suspension.
