Summary: The Rancho RS5000X series provides a sophisticated upgrade for the 1999-2007 GMC Sierra 1500 4WD, utilizing advanced twin-tube gas pressure technology to improve ride quality.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition of fluid to ensure smooth street comfort and responsive handling.
• Twin-Tube Gas Pressure: A 150 PSI nitrogen gas charged design minimizes aeration and foaming to provide consistent damping performance in various temperatures.
• Large Shock Body: A 2.25-inch diameter reserve tube increases fluid capacity to ensure cooler operating temperatures and reduced fade during extended use.
• Nitro-Carburized Piston Rod: Heavy-duty construction with a specialized coating provides superior scuff and corrosion resistance to ensure a long service life.
