Smooth out the ride and help keep the rear end planted with the KYB Excel-G Suspension Shock Absorber 344464, a nitrogen gas-charged, twin-tube shock built to restore your vehicle's original ride control, stability, and handling. It installs as a direct-fit rear shock for the 2004-2012 Chevrolet Colorado, 2004-2012 GMC Canyon, 2006 Isuzu I-280, and 2007-2008 Isuzu I-290 — see the Buyer's Guide tab for engine-level details.
- OEA (Original Equipment for the Aftermarket): made on the same KYB OE assembly lines with the same OE-quality components, calibrated to restore the vehicle's designed performance rather than change it.
- Twin-tube, nitrogen gas-charged design: the Excel-G is KYB's recommended OEM-replacement shock for trucks and is designed to help restore the vehicle's control and handling.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand assembled in-house to manage tire contact, steering response, and body movement; strong, thick strut bodies and brackets help minimize flex to maintain correct alignment.
Worn rear shocks may show as excessive bounce, nose dive, sway, or poor body control; if a failed shock is the cause, this replaces it. Sold individually — replace both sides as a pair for balanced ride control.
