Product Details

KYB Excel-G shocks and struts are focused on restoring the vehicle’s original ride characteristics rather than changing them. The 3440237 is an OEA-style replacement for drivers who want predictable control during braking, lane changes, and uneven-road driving. This part cross-references Monroe Shocks & Struts (e.g., 84805964) for the same application. Fits 2019-2021 Chevrolet Silverado 1500, rear with off road suspension; Fits 2022 Chevrolet Silverado 1500 LTD, rear with off road suspension; Fits 2019-2021 GMC Sierra 1500, rear with off road suspension, without factory lift; Fits 2022 GMC Sierra 1500 Limited, rear with off road suspension.

What It Helps Address

• Excessive rear-end bounce after bumps
• Reduced stability during braking and lane changes
• Loose or unsettled handling on rough pavement
• Loss of factory ride control from worn shocks
• Uneven damping response in off-road suspension setups

Installation Notes and Tips

Verify rear suspension configuration before ordering, especially off-road suspension and factory lift details. Compare compressed length, extended length, and mount style to the original shock before installation. For best results, replace shocks in matched axle pairs and inspect related suspension bushings, mounts, and hardware condition during service.
