Restore controlled, confident ride quality with the KYB shock absorber (MPN 3440089), a rear-position Excel-G unit that drops in as a KYB-recommended OEM replacement for the 2015-2022 Chevrolet Colorado and 2015-2022 GMC Canyon (see the "Vehicles it fits" section for engine-level detail). This is the nitrogen gas-charged, twin-tube design KYB calls Excel-G, built to restore the vehicle's original designed control and handling rather than change it.
Excel-G carries the OEA classification (Original Equipment for the Aftermarket) because it's made on the same KYB OE assembly lines, using the same OE-quality components and calibration.
- Nitrogen gas-charged twin-tube design: a KYB gas shock absorber built to OE quality standards.
- Triple lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand assembled in-house to correctly manage tire contact, steering response and body movement.
- Supports electronic safety systems: helps keep the suspension performing as the manufacturer intended.
Worn shocks can show up as excessive bounce, nose-dive under braking, or reduced stability during lane changes; if a failed rear shock is the cause, this replaces it. Replace shocks in pairs across an axle for balanced ride control.
