Bilstein B8 5100 Rear Shock

The Bilstein B8 5100 is a direct-fit suspension shock absorber for lifted applications that need controlled damping and consistent road feel. It uses a monotube design and a velocity-sensitive digressive piston to respond to changing road conditions with stable performance.

Fits 2018-2026 Jeep Wrangler, rear, for vehicles with 0-1.5" rear lift. Part number 33-316321 is tuned for the specific application to help restore ride quality, handling, and comfort on the Jeep Wrangler.

• Monotube internal design for consistent fade-resistant performance.
• Velocity-sensitive digressive piston for responsive damping changes.
• Non-adjustable shock absorber with smooth-body construction.
• Zinc-plated finish for added corrosion resistance.
• Black bellows boot included for added protection.

Detailed Fitment and Design

This Bilstein shock absorber is built around a smooth-body, non-coilover layout with eye-to-eye 12.8 mm mounts at both ends. The 46 mm body diameter, 16.93-inch collapsed length, and 26.94-inch extended length support the intended rear suspension geometry for lifted Jeep Wrangler applications. Part number 33-316321 is part of the B8 5100 line, which is engineered as a direct-fit solution for lifted trucks and SUVs.

The B8 5100 product line focuses on application-specific tuning rather than adjustable settings, giving the shock a consistent response across the intended lift range. This part cross-references Rancho RS77064 for the same application.

Common Issues It Can Address
