Rancho RS55282 RS5000X Front Shock Absorber for 2002-2005 Dodge Ram 1500 4WD

Vehicle Fitment

• 2002-2005 Dodge Ram 1500 (4WD, Standard Cab, 3.7L V6)
• 2002-2005 Dodge Ram 1500 (4WD, Standard Cab, 4.7L V8)
• 2002-2005 Dodge Ram 1500 (4WD, Standard Cab, 5.7L HEMI V8)
• 2002-2005 Dodge Ram 1500 (4WD, Quad Cab, 3.7L V6)
• 2002-2005 Dodge Ram 1500 (4WD, Quad Cab, 4.7L V8)
• 2002-2005 Dodge Ram 1500 (4WD, Quad Cab, 5.7L HEMI V8)

Fitment Notes

• Fits 4WD (4x4) models only - does not fit RWD (2WD) configurations
• Designed for factory ride height (0" lift) - not suitable for lifted applications
• Year range ends at 2005 due to a front suspension redesign on the Ram 1500 beginning with the 2006 model year - 2006 and later models require a different shock
• Customers running lift kits should select an extended-length RS5000X shock sized for their specific lift height

Features

• Rancho exclusive Cross Tuned Technology pairs a patented rebound valving system with an advanced compression phase for improved handling and control on- and off-road
• Progressive Engagement Valving custom-tuned for the 2002-2005 Ram 1500 4WD platform - gradually controls fluid flow at low speeds to absorb initial impacts without transmitting harshness into the cab
• Compression Control Valve regulates fluid transfer to absorb road impacts without disc flutter, maintaining consistent damping throughout shock travel
• Twin-tube, gas-pressurized design at 150 PSI minimizes air-to-oil foaming and prevents damping fade during sustained or demanding use
• 2-1/4" (57mm) diameter shock body holds greater fluid volume for cooler operating temperatures and better control across varying speeds and terrain
• All-weather fluid rated for internal temperatures from -40°F to 248°F, ensuring reliable performance in extreme cold or heat
• Low-friction, self-lubricating seal retains gas and oil for faster rebound response and smoother compression over the life of the shock
• 16mm nitro-carburized piston rod resists scuffing and corrosion for long-term durability under daily and off-road use
• 35mm sintered iron, glass-filled Fluon banded piston delivers precise shock motion control and enhanced responsiveness to changing road conditions
• Protective boot included to shield the shock rod and seal from dirt, debris, and moisture

Product Description

The Rancho RS55282 RS5000X is a front shock absorber engineered specifically for 2002-2005 Dodge Ram 1500 trucks equipped with 4WD (4x4), running at factory ride height. Built on Rancho's patented Cross Tuned Technology, this shock integrates an exclusive rebound valving system with an advanced compression phase that works together to deliver significantly improved handling, stability, and ride quality compared to OEM dampers. The Progressive Engagement Valving is custom-tuned for the Ram 1500 4WD front suspension geometry - at low speeds and in the early stages of shock travel, the valving engages gradually to absorb initial bumps and reduce cab harshness. As road inputs intensify, the valving progressively tightens its response to maintain control and composure whether on pavement, dirt roads, or off-road terrain.

The twin-tube, gas-pressurized construction at 150 PSI keeps air-to-oil foaming under control, a key advantage for heavy trucks that are frequently loaded, towed with, or driven on rough surfaces where sustained shock cycling is common. The enlarged 2-1/4" shock body holds more damping fluid than narrower designs, allowing it to operate cooler and maintain consistent damping performance over longer periods. All-weather fluid formulation keeps the shock operational from -40°F to 248°F internally, providing year-round reliability regardless of climate. The 16mm nitro-carburized piston rod and 35mm sintered iron Fluon-banded piston further enhance longevity and responsiveness, resisting corrosion and delivering smooth, precise control through the full range of suspension travel.

The RS55282 is a direct-fit front replacement for 2002-2005 Dodge Ram 1500 4WD models across all available engine configurations - 3.7L V6, 4.7L V8, and 5.7L HEMI V8 - in Standard Cab and Quad Cab body styles. Installation uses factory mounting hardware along with the included hardware kit; no fabrication is required. This shock is specifically designed for 4WD models and does not fit 2WD/RWD configurations. It is also rated for factory ride height only - owners running lift kits should select an appropriate extended-length RS5000X variant. The 2006 Ram 1500 4WD transitioned to a revised front suspension setup, making the RS55282 compatible with 2002-2005 model years exclusively. Backed by Rancho's Limited Lifetime Warranty, the RS55282 is a durable, well-matched upgrade for Ram 1500 4WD owners looking to restore or improve front suspension performance at stock ride height.
