FOX Factory Race Series 2.5 Internal Bypass 2-3 inches Front Lift Shocks for 2003-2024 Toyota 4Runner 2WD/4WD

Part Number: 883-06-227

Summary: The FOX Factory Race Series 2.5 Internal Bypass shocks provide the ultimate performance upgrade for the Toyota 4Runner, offering velocity and position-sensitive damping technology. By utilizing patented Internal Bypass technology, these shocks manage high-speed off-road impacts while maintaining a comfortable ride through multiple damping zones. The addition of a Dual Speed Compression (DSC) adjuster allows for precise manual tuning to handle varying loads and terrain, ensuring sustained performance under demanding conditions.

Features

• Internal Bypass Technology: Patented internal bypass design provides multiple zones of damping control to ensure increased capacity through rough terrain and protection against bottom-outs.
• Dual Speed Compression (DSC): External DSC adjuster provides manual tuning of high and low-speed compression to ensure the vehicle is dialed in for specific loads and driving styles.
• Aluminum Body: 2.5-inch impact-extruded and CNC-machined 6061-T6 aluminum body provides Type III hard anodization to ensure resistance to corrosion and wear.
• External Reservoir: Remote reservoir configuration provides increased oil capacity and houses an Internal Floating Piston (IFP) to ensure consistent damping by separating shock oil from the nitrogen charge.
• Hard Chromed Shafts: 7/8 inches hard chromed steel shafts provide a robust internal structure to ensure durability during high-speed operation.

Technical Specifications

Fitment

• 2003-2024 Toyota 4Runner
• Note: Fits both 2WD and 4WD models.

What’s Included

• Sold Individually
• Application-specific springs
• External reservoir and mounting hardware

Why Choose This Product?

• Engineering Advantage: The Internal Bypass design allows fluid to bypass the main piston through bleed holes in the ride zone, only forcing fluid through the main piston as the shock extends past that zone for progressive bottom-out and top-out control.
• Performance Benefit: Drivers experience a “catch” for landings and high-speed stability without sacrificing the initial comfort required for daily driving.

Frequently Asked Questions

What does the Internal Bypass technology do?
It allows for position-sensitive damping, meaning the shock can be plush in the ride zone while becoming progressively firmer at the ends of the stroke to prevent harsh bottoming or topping out.

Can I adjust these shocks for different weights?
Yes, the Dual Speed Compression (DSC) adjuster allows you to dial in the shock for different loads, environments, and driving styles.

Do these shocks help with heat management?
Yes, the 2.5-inch aluminum bodies and external reservoirs increase oil capacity and use an Internal Floating Piston (IFP) to keep temperatures cool and damping consistent.
