Rancho RS5000X 0-2″ Rear Lift Shocks for 1987-1991 GMC V3500 4WD

Part Number: RS55132

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to significantly improve the ride quality of your GMC V3500. Engineered for vehicles with 0-2 inches of rear lift, these shocks feature a unique progressive engagement valving system that minimizes harshness during initial impacts. This gas-pressurized solution provides the perfect balance of on-road comfort and off-road durability for classic 4WD heavy-duty applications.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping cycles to ensure a smoother ride over choppy terrain.
• Twin-Tube Gas Pressure: A 150 PSI nitrogen gas charge reduces aeration and foaming to provide consistent damping performance during sustained use.
• Large Shock Body: The 2.25-inch diameter reserve tube increases oil capacity to ensure lower operating temperatures and reduced fade under load.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides increased tensile strength and corrosion resistance to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my GMC V3500?
No, these shocks do not create lift. They are specifically valved and lengthened to accommodate vehicles already equipped with 0-2 inches of rear lift.

What is the benefit of the twin-tube design for my truck?
The twin-tube design is exceptionally durable; the outer tube can take a dent from a rock or debris without affecting the movement of the inner piston, ensuring you don’t get stranded off-road.

Are the shock boots included?
Yes, this pair includes Rancho’s signature protective boots to shield the piston rod from salt, mud, and road grime.
