KYB SB125 Suspension Strut Bellows - Rear

KYB Strut Boot Kit SB125 Overview

KYB SB125 is a rear suspension strut bellows kit that helps shield the strut shaft from dirt, dust, sand, salt, and other road debris. By covering the polished shaft and protecting the upper seal and bushing, it supports longer strut life on a wide range of rear applications, including Ford Fiesta, Volkswagen Golf, and Audi Q5 models.

Key Features

• Superior-quality boot helps protect the strut shaft from leak-causing dirt and debris
• Poly foam bumper helps prevent the strut from bottoming out
• Built to match or exceed OE design and quality
• Protects the upper seal and bushing from contamination and wear
• Rear suspension strut bellows for select Ford, Volkswagen, Audi, and Mazda applications

Product Details

The KYB Boot Kits line focuses on protecting suspension components from the road conditions that shorten strut service life. This KYB strut boot kit uses a durable plastic bellows to cover the full strut shaft, helping keep abrasive contaminants away from the seal area. The included poly foam travel-limiting bumper adds impact protection by reducing the chance of bottoming out, which can help limit damage to nearby suspension parts during extreme movement.

Common Problems It Helps Address

• Strut shaft wear caused by dirt, dust, sand, and salt
• Seal contamination that can lead to fluid leakage
• Bushing wear from road debris exposure
• Bottoming-out impact that can stress the strut assembly
• Damage from extreme suspension travel on rough roads

Installation Notes and Tips

Install the boot on the rear strut assembly during strut service or replacement for best access. Inspect the shaft, seal area, and surrounding suspension components before installation, and verify vehicle-specific fitment for your exact year, make, model, and rear suspension configuration. The 2009-2016 Audi Q5 listing is not compatible with electronic suspension systems.

Quality Assurance
