Bilstein 46-274021 Suspension Shock Absorber Conversion Kit - Rear

Bilstein B6 4600 Rear Shock Conversion Kit

The Bilstein B6 4600 shock absorber conversion kit is built for vehicles originally equipped with rear Nivomat load-leveling shocks. It replaces the self-leveling setup with a standard coil spring suspension while restoring factory ride height and improving rear suspension control.

For Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon rear suspension service, Bilstein 46-274021 provides a direct conversion solution with Bilstein B6 4600 monotube dampers and matching springs. The result is a more controlled ride with consistent support after removing the OE Nivomat system.

Key Features

• Bilstein B6 4600 series rear shock absorber conversion kit
• Non-adjustable damping for straightforward replacement
• Monotube internal design with a 46mm body diameter
• Velocity-sensitive digressive piston for changing road conditions
• Includes blue straight boot and yellow painted finish

• Rear position application for standard coil spring conversion

Product Details

The B6 4600 line is Bilstein’s performance-oriented replacement series for OE suspension systems, and this kit is tailored to vehicles that need to eliminate rear Nivomat self-leveling shocks. By pairing replacement springs with monotube shock absorbers, Bilstein 46-274021 helps return the rear suspension to proper height and improves ride quality, handling response, and comfort. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 2002-2006 Cadillac Escalade, rear; 2000-2006 Chevrolet Tahoe, rear; and 2000-2006 GMC Yukon, rear. Search terms such as rear shock conversion kit for Nivomat suspension, Bilstein B6 4600 rear shocks, and standard coil spring conversion for Escalade Tahoe Yukon all point to this application.

What This Part Helps Address

• Rear ride height loss after removing Nivomat self-leveling shocks
• Soft or inconsistent rear suspension response
• Reduced handling control from worn OE load-leveling components
• Uneven rear stance caused by failed self-leveling dampers
• Need for a standard coil spring suspension conversion

Installation Notes and Tips

Install this kit only on the rear suspension of the listed vehicles with OE Nivomat self-leveling equipment. Verify that the vehicle is being converted to standard coil spring suspension before installation. Follow factory service procedures for spring and shock replacement, and inspect related rear suspension components for wear while the system is apart.

Quality Assurance
