Rear Shock Absorber for 2017-2018 GMC Acadia & More - KYB 3440145

Keep the rear ride settled and body movement in check with the KYB shock absorber 3440145, a nitrogen gas-charged, twin-tube Excel-G unit built on KYB's OE assembly lines. This rear-position gas shock drops in as a direct-fit replacement for the 2017-2018 Cadillac XT5 and 2017-2018 GMC Acadia (see the "Vehicles it fits" section for engine-level fitment).

The Excel-G is KYB's Original Equipment for the Aftermarket (OEA) line, calibrated to restore the vehicle's designed damping performance rather than change it — the preferred choice of many professional technicians and a recommended OEM-replacement shock for SUVs and crossovers.

• Nitrogen gas-charged twin-tube design: uses the same OE-quality components found in KYB's global OEM products.
• Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
• Vehicle-specific, hand-assembled damping valves: manage tire contact, steering response and body movement.
• Supports electronic safety systems: helps keep the suspension operating as the vehicle manufacturer intended so those systems perform as designed.

Worn shocks can show up as excessive bounce, nose dive, or reduced stability; if the rear shock is the cause, this KYB gas shock absorber replaces it. Sold individually — replace both rear shocks together as a matched pair for balanced ride control.
