Product Details

The Rancho RS5000X RS55379 shock absorber delivers improved on-road and off-road handling through innovative engineering and durable construction. At the core of this shock is Rancho's unique and patented rebound valving system combined with an advanced compression phase, designed to elevate vehicle performance across all driving conditions.

Cross Tuned Technology and Advanced Valving:

  • Patented progressive rebound and compression discs with eccentric disc design that engages valving at lower frequencies
  • Progressive Engagement Valving allows early fluid flow to reduce harsh initial impacts
  • Custom-tuned compression control valve regulates fluid transfer to absorb impacts without disc flutter
  • Gas pressurized to 150 PSI to minimize foaming and shock fade

Built for Durability:

  • Double-welded loops, high-capacity twin-tube construction, and nitro-carburized rod
  • 2-1/4-inch diameter shock body for increased fluid capacity and cooler operation
  • All-weather fluid withstands internal temperatures between -40 and 248 degrees Fahrenheit
  • Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression
  • Includes red polyvinyl accordion protection boot for rod and seal protection

Additional Features:

  • Glass-filled Fluon banded piston for smoother travel and greater responsiveness
  • Black natural rubber bushings for vibration reduction
  • Collapsed length: 16.12 inches; Extended length: 25.31 inches
  • Designed for vehicles with 0-2.50 inch lift
  • Includes mounting hardware (bushings, washers, nuts)

The RS5000X series is engineered to handle everything from daily commuting to serious off-road use, providing consistent performance and reliability across all terrains.

Good shop

great so far

No issues so far. Easy ordering and checkout

quick checkout process

Autoplicity was the cheapest place I could find for my Turbosmart Eboost2. I ordered my controller yesterday and they promptly gave me a receipt and a normal time frame for delivery. Today I got the tracking number and at lunch I got an email saying order complete and delivered. This was an awesome experience and I will definitely be using them next time i'm in the market for a similar product.

Quick and easy!

great
