Fully adjust your lift and eliminate load-induced sag with the Bilstein B8 8100 ZoneControl DSA front shock for 2005–2026 Ford F‑250 and F‑350 Super Duty.

Engineered specifically for heavier-than-oem Super Duty pickups, this monotube shock combines ride‑height tuning with precision damping to keep your truck level under maximum payload or aftermarket wheel‑and‑tire packages.

• Precise Year‑to‑Year Fitment: Direct bolt‑on replacement for 2005–2026 Ford F‑250/F‑350 front suspension positions, eliminating custom bracketing or alignment guesswork.
• Dual‑Speed Adjustable Damping (DSA): Integrated zone‑valve technology separates low‑speed shaft movements for daily comfort from high‑speed valve action to control bump impacts and off‑road transitions.
• ±2 Inch Ride Height Adjustment: Factory‑zone clearance dial lets you fine‑tune lift levels while preserving original steering geometry, reducing premature tire wear and tracking issues.
• Nitrogen‑Charged Monotube Design: Single‑chamber steel construction pressurized with inert gas virtually eliminates fluid foaming and heat fade during sustained hauling or highway cruising.
• Corrosion‑Rated Housing: Zinc‑coated outer cylinder paired with a polished chrome‑plated piston rod resists road salt, mud, and UV degradation far beyond original equipment seals.
• Heavy‑Duty Dust Wiper System: Precision‑machined internal wiper rings block abrasive debris before it reaches the primary seal, significantly extending service intervals and maintaining consistent damping force.

Package Specifications: Each unit ships at 22.25 lbs with an approximate installed envelope of 32 × 14 × 6 inches. Includes necessary mounting hardware and matches standard aftermarket spring retainers for lifted Super Duty builds.
