Bilstein 5100 Series 2004 Ford F-150 Lariat 4WD Rear 46mm Monotube Shock Absorber

Upgrade your F-150's rear suspension with this 5100 Series shock engineered for light-duty trucks managing demanding loads and occasional off-road excursions. The 46mm monotube construction with digressive piston delivers adaptive damping that transitions seamlessly between unloaded daily driving and fully-loaded hauling operations. Application-specific valving accounts for F-150's substantial payload capacity and rear leaf spring rates, controlling axle movement during acceleration while preventing harsh rebound when traversing uneven terrain. High-pressure nitrogen charge maintains separation between hydraulic fluid and gas, preventing cavitation during rapid suspension movements encountered on rough roads or moderate trails. This rear-position shock manages weight transfer precisely, reducing squat under load while maintaining balanced handling characteristics. Single-tube design allows superior heat dissipation compared to twin-tube alternatives, crucial for sustained performance when towing trailers or navigating challenging terrain. Zinc-plated finish resists environmental damage and undercarriage debris common to truck operation. Direct bolt-on installation integrates with factory mounting points without modifications, preserving proper geometry while substantially improving control authority.

Enhance your F-150's versatility with damping technology designed for trucks that work during the week and play on weekends. This shock delivers the balanced performance light-duty truck owners demand from vehicles serving multiple roles.
