Rancho 99-04 Ford Pickup / F250 Series Super Duty Rear RS5000X Shock

If you're working on a 1999-2004 Ford F-250 Super Duty and need to replace the rear shocks, this Rancho RS5000X is a solid option. It's built to handle both daily driving and tougher conditions, offering an improved ride and better control for your truck.

Rancho uses a unique valving system and a large twin-tube body that helps keep things cool, even when you're pushing it. The 16mm nitro-carburized piston rod is strong, resisting scuffs and corrosion, while the double-welded loops at stress points add extra durability. Inside, a 35mm sintered iron piston and a fluon-banded piston work together to give you more responsive control over the shock's movement, adapting to changing road conditions for a smoother experience.

This shock also features a nitrogen gas charge at 150 PSI, which helps prevent the fluid from foaming and losing its damping ability, especially during extended use. The polyurethane rebound bumper and rubber bushings are there to soak up impacts and minimize harshness, making your ride more comfortable. Rancho backs this shock with a Limited Lifetime Warranty, giving you peace of mind.
