Rancho Suspension Shock Absorber P/N:RS55367

Smooth out the ride and keep the rear axle planted with the Rancho RS5000X shock absorber RS55367, a rear-position damper for the 2009-2010 Dodge Ram 1500, the 2011-2021 RAM 1500, and the 2019-2024 RAM 1500 Classic — see the Buyer's Guide tab for engine-level fitment. This Rancho shock absorber uses the brand's exclusive Cross Tuned technology, pairing a rebound valving system with an advanced compression phase to help improve overall on- and off-road handling.

• Custom-tuned valving: Progressive Engagement Valving is tuned per application to help reduce initial low-speed impacts and minimize a rough ride, while the Compression Control Valve regulates fluid transfer to help maintain shock motion control.
• Strong and durable: 16mm nitro-carburized piston rod resists scuffs and corrosion, with double-welded loops at stress areas, a 35mm sintered iron piston, and a polyvinyl protective boot.
• Temperature ready: a large twin-tube body filled with all-weather fluid supports cooler operation and withstands internal temperatures from -40 to 248°F.
• Fade resistant: nitrogen gas pressurized to 150 PSI helps minimize air-to-oil mixing to reduce damping fade and foaming.

A polyurethane rebound bumper, rubber bushings, and a fluon-banded piston help absorb harshness for a smoother ride. Backed by Rancho's Limited Lifetime Warranty. For balanced handling, replacing the shocks on an axle as a matched pair is recommended.
