Bilstein 24-021289 Suspension Shock Absorber - Rear

Bilstein B6 4600 Rear Shock Absorber

The Bilstein B6 4600 shock absorber is a direct-fit upgrade for stock-height light trucks and SUVs that need more controlled rear suspension performance. This rear shock uses a monotube design and a velocity-sensitive digressive piston to deliver consistent damping across changing road conditions.

Built for application-specific tuning, the Bilstein B6 4600 line is aimed at improving ride quality, handling, and comfort without changing factory ride height. Part number 24-021289 is a rear suspension shock absorber for select Nissan Frontier and Toyota T100 applications.

Detailed Description

Bilstein B6 4600 24-021289 is engineered as a rear shock absorber upgrade for vehicles that retain factory ride height or use a mild rear lift within the listed fitment. The monotube construction helps maintain stable damping performance, while the digressive piston reacts to road inputs to better control body motion over rough pavement, expansion joints, and uneven surfaces. This makes it a practical choice for drivers looking to restore rear suspension control on a Nissan Frontier or Toyota T100.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For shoppers searching for a rear shock absorber for 1998-2004 Nissan Frontier or 1993-1998 Toyota T100, 24-021289 is the Bilstein B6 4600 option to compare against OE-style replacements.
