Jeep Wrangler JK 07-17 Performance Elite Series, 2.5, R/R, DSCA, Internal Bypass, 2.5-4", Stage 5, Front Shock, Pair

Take your Jeep JK or JKU's suspension to race-level performance with the FOX Factory Race Series 2.5 Internal Bypass Shocks. Designed as a bolt-on upgrade, these high-performance shocks deliver velocity- and position-sensitive damping, DSC adjustability, and superior terrain control—whether you’re crawling rocks, tearing through the desert, or hammering rugged trails at speed. Key Features

•  Internal Bypass Technology
  FOX’s patented internal bypass system provides multi-zone damping by redirecting shock fluid around the piston within the ride zone, and then gradually increasing resistance outside of it. This results in:
  • A smooth, plush ride on-road and over mild terrain
  • Progressive bottom-out control on hard hits
  • Gentle top-out protection on full extension
  • Precise rebound/catch on landings

• Dual Speed Compression (DSC) Adjusters
  Tune your Jeep for load, trail type, or comfort preference with external knobs for both:
  • Low-speed compression (LSC): cornering, body roll, and daily driving
  • High-speed compression (HSC): off-road hits, whoops, jumps, or rough trails
• External Reservoir w/ Internal Floating Piston (IFP)
  Keeps oil and nitrogen separate, preventing cavitation and maintaining damping consistency—especially under prolonged abuse or high-speed runs.
• Durable & Corrosion Resistant
  • 2.5” Type III anodized 6061-T6 aluminum bodies resist wear and corrosion
  • CNC-machined aluminum components ensure strength without excessive weight

 Frequently Asked Questions (FAQ)

Q: What’s the difference between internal and external bypass shocks?
A: Internal bypass shocks hide the bypass circuits inside the shock body for a clean, compact bolt-on solution. External bypass shocks require more space and are typically used on long-travel race setups.

Q: How do DSC adjusters improve my ride?
A: They allow you to tune your shock damping for either low-speed comfort/control (e.g., daily driving or crawling) or high-speed resistance (e.g., trail whoops or rocky hits).

Q: Do I need a lift kit to install these?
A: Yes, these are designed for lifted JK/JKU setups. Be sure to match the shock length to your lift height.

Q: Are these rebuildable?
A: Absolutely. All FOX Factory Race Series shocks are fully rebuildable and revalveable for long-term use and custom tuning.

Q: Can I install them myself?
A: While installation is bolt-on, professional help is recommended if you’re tuning for specific compression zones or pairing with aftermarket suspension components.
