Restore the settled ride and directional control of your truck with the KYB Excel-G Shock Absorber (MPN 3440089), a nitrogen gas-charged, twin-tube rear shock that drops in as a direct-fit replacement for the 2015-2022 Chevrolet Colorado and 2015-2022 GMC Canyon. Excel-G isn't a performance upgrade — it's calibrated to restore the ride control, stability, stopping, lane-change responsiveness, and handling the vehicle was originally designed to deliver, which is why KYB gives it the OEA (Original Equipment for the Aftermarket) classification.
- OE-quality build: Made on the same KYB assembly lines and with the same OE-quality components used for KYB's global new-vehicle programs.
- Triple-lip fluid seal: Uses a triple-lip fluid seal to reduce the chance of oil and gas leaking out.
- Vehicle-specific valving: Hand-assembled, application-specific damping valves manage tire contact, steering response, and body movement.
- Supports safety systems: Helps keep electronic safety systems performing as designed, since they depend on the suspension, brakes, and tires working as intended.
Worn shocks may show up as excessive bounce, nose-dive under braking, or poor body control over bumps. If a failed rear shock is the cause, this KYB Excel-G unit replaces it.
