Bilstein 24-261630 Suspension Shock Absorber - Rear

Bilstein B6 4600 Rear Shock for Colorado and Canyon

The Bilstein B6 4600 rear shock absorber is a direct-fit upgrade for stock-height light trucks and SUVs. This application-specific shock uses a monotube design and a velocity-sensitive digressive piston to deliver consistent damping as road conditions change.

Compatible with 2015-2022 Chevrolet Colorado rear and 2015-2022 GMC Canyon rear, part number 24-261630 is tuned for the rear suspension on each listed application. The yellow-painted body and blue straight boot identify the Bilstein B6 4600 series.

Product Details

Bilstein B6 4600 shocks are part of the B6 4600 line, a series focused on OE-style replacement performance for stock-height trucks and SUVs. For the Chevrolet Colorado and GMC Canyon rear suspension, this shock absorber is engineered to improve ride control, handling response, and comfort without changing the vehicle’s stock ride height. Part number 24-261630 is a rear shock absorber built around Bilstein’s monotube architecture, which helps maintain stable damping under repeated use.

This part cross-references Monroe Shocks & Struts (e.g., 985-24-129, RS5023) for the same application.

What This Shock Absorber Helps Address

• Excessive rear-end bounce over bumps and uneven pavement
• Reduced control during braking, cornering, or load changes
• Worn OE shock performance on stock-height suspension
• Inconsistent damping as the shock heats up during use
• Harsh or unsettled rear ride quality on Colorado and Canyon models

Installation Notes and Tips

Install 24-261630 on the rear position only for the listed Chevrolet Colorado and GMC Canyon applications. Verify mount style, body diameter, and vehicle year before installation. Because this is a non-adjustable shock absorber, no damping tuning is required after installation. Always inspect related suspension components, including bushings and mounts, before replacing the shock.

Quality Assurance

Bilstein designs the B6 4600 series as an application-specific shock absorber line with tuned damping for each listed vehicle. Part number 24-261630 is built to Bilstein’s monotube performance standards for the rear suspension of 2015-2022 Chevrolet Colorado and 2015-2022 GMC Canyon models.
