KYB is a leading supplier of shocks and struts to new-vehicle manufacturers. It makes the Excel-G on the same KYB OE assembly lines with the same OE-quality components, which earned it the OEA (Original Equipment for the Aftermarket) classification.
- Gas-charged twin-tube design: nitrogen gas-charged, twin-tube construction that includes every quality component found in KYB's global OEM products.
- Triple lip fluid seal: helps reduce the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand-assembled in-house and designed to manage tire contact, steering response and body movement.
- Strut body and brackets: KYB states its strut bodies and brackets are the strongest and thickest in the industry, minimizing flex to help maintain correct alignment.
Electronic safety systems depend on the suspension, brakes and tires working as the vehicle manufacturer intended, and the Excel-G helps keep them performing as designed. Made in USA.
To reduce the chance of noise and vibration, KYB recommends new strut mounts, part number SM5395, plus a KYB Strut Boot, part number SB108, to shield the strut from dirt, debris and salt. Replacing both front struts together is recommended for balanced handling.
