Rancho RS5000X 1-2.5″ Front Lift Shocks for 2011-2020 GMC Sierra 3500HD
Part Number: RS55378
Summary: The Rancho RS5000X Series gas-pressurized shock absorber is engineered to provide enhanced durability and ride quality for your GMC Sierra 3500HD. Specifically valved for vehicles with 1 to 2.5 inches of front lift, these shocks utilize a twin-tube design to provide consistent damping and dent resistance during off-road use. This setup resolves the harsh ride quality often associated with leveled heavy-duty trucks by optimizing fluid capacity and heat dissipation.
Features
- Progressive Engagement Valving: Custom-tuned internal valving provides a smooth transition between low and high-speed impacts to ensure driver comfort over varied terrain.
- Gas Pressurized Twin-Tube: Nitrogen gas charge provides reduced aeration and foaming to ensure consistent performance during heavy-duty hauling or towing.
- 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural integrity and corrosion resistance to ensure a long service life.
- Protective Boot: A durable red polyvinyl accordion boot provides a physical barrier against road debris and salt to ensure seal longevity.

Frequently Asked Questions
Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically sized and valved to be used on trucks that already have 1 to 2.5 inches of front lift via torsion key adjustments or leveling kits.
Can I use these with my factory shock spacers?
No, these shocks are not for use with aftermarket shock spacers or relocation brackets as it may cause the shock to bottom out and fail prematurely.
What is the benefit of the twin-tube design?
The twin-tube design provides an outer reserve tube that protects the inner working cylinder from dents and trail damage, ensuring the shock continues to function even in harsh environments.
