Detailed Description

KYB SR2004 is part of the SR Series, a line focused on self-leveling suspension service for GM SUVs. This rear shock absorber is built to restore the vehicle’s original ride height and help maintain consistent handling and control when the suspension is carrying load. With a compressed length of 15.77, extended length of 22.79, and stroke length of 7.02, it is sized for the specified rear applications and uses matching upper and lower E2 mounts for OE-style installation.

This part cross-references Monroe Shocks & Struts (e.g., 40209) for the same application. It is a fitment-based replacement for the rear suspension on 2000-2006 Chevrolet Suburban 1500 and 2000-2006 GMC Yukon XL 1500 with ZW7 Premium Smooth Ride Suspension, excluding Z55 Autoride Suspension. KYB SR2004 is also identified by part number SR2004 for catalog and search use.

What It Helps Address

• Rear ride height that has dropped from normal operating position
• Uneven suspension balance on self-leveling GM SUVs
• Reduced rear-end control during load changes

Installation Notes and Tips

Compatible With 2000-2006 Chevrolet Suburban 1500, rear, recommended OEM replacement; w/ ZW7 Premium Smooth Ride Susp. (Exc. Z55 Autoride Susp.); SR Series. Compatible With 2000-2006 GMC Yukon XL 1500, rear, recommended OEM replacement; w/ ZW7 Premium Smooth Ride Susp. (Exc. Z55 Autoride Susp.); SR Series.

Verify suspension package and rear mounting dimensions before installation. Because this is a self-leveling shock absorber, confirm the vehicle is equipped with the listed ZW7 Premium Smooth Ride Suspension and not Z55 Autoride. SR2004 uses OE-style upper and lower E2 mounts, so proper alignment of the mounting points is important during service.
