Product Details
The Bilstein B8 shocks are built for a 2013-2026 Dodge Ram 3500 (DS/DT) that has been lifted or leveled, valved for the taller ride height rather than fighting it.
The monotube design is what sets Bilstein apart. A single high-pressure gas chamber keeps the oil from aerating, so the damping stays consistent on a rough road instead of fading as the unit heats up.
Features
- 46mm monotube design ensures consistent, fade-free performance in all conditions
- Self-adjusting deflective disc valving reacts immediately to surface changes enabling maximum vehicle control
- Remote reservoir increases shock oil capacity for greater heat dissipation
