FOX 3.2 Factory Race Series Internal Bypass Shocks for 2024+ Toyota Land Cruiser / Lexus GX 550 / 2025+ Toyota 4Runner
The FOX 3.2 Factory Race Series Internal Bypass shocks are purpose-built for the LC250, GX550, and 2025+ 4Runner platform. These aren't repurposed off-the-shelf shocks - FOX engineered this kit specifically for your chassis with vehicle-specific valving, spring rates, and geometry to deliver a measurable improvement in both on-road comfort and off-road control.
The patented internal bypass design creates multiple damping zones within the shock body. In the ride zone, fluid bypasses the main piston for a plush, compliant feel on normal terrain. As the shock compresses deeper - into rough trail conditions or a hard landing - the bypass bleed holes terminate and the full piston takes over, building force progressively to prevent harsh bottoming. It's the same technology FOX runs in desert racing, adapted for a bolt-on street and trail truck.
The finned reservoir houses a DSC EVO (Dual Speed Compression Evolution) adjuster with Variable Valve Control on the high-speed circuit. Unlike most adjusters that add preload to change high-speed damping, DSC EVO uses independent high and low-speed circuits - so you can add big-hit control without stiffening small-bump feel. The 3.2" diameter Type II anodized aluminum body handles sustained heat from extended hard use and resists corrosion long-term.

Why FOX?
FOX Factory Race Series sits between OEM performance kits and full custom race builds. Every kit goes through vehicle-specific dynamometer testing before it ships. These aren't universal shocks with adapter brackets - they're engineered for this exact platform.
Frequently Asked Questions
What vehicles do these fit?
The 2024+ Toyota Land Cruiser (LC250), 2024+ Lexus GX 550, and 2025+ Toyota 4Runner. Front and rear are separate SKUs sized specifically for each position.
What lift range do these support?
The front shock (883-06-253) supports 1-3" of lift. The rear shock (883-26-169) supports 0-1.5" of lift.
What's the difference between Front Only, Rear Only, and Front + Rear?
Front Only and Rear Only let you upgrade a single axle. The Front + Rear combo includes both shocks for a complete suspension upgrade - most builds benefit from matching shocks front and rear for balanced geometry and consistent damping behavior.
What does DSC EVO mean?
DSC EVO (Dual Speed Compression Evolution) is FOX's high-speed compression adjuster. Variable Valve Control lets you tune high-speed damping independently without affecting small-bump feel - you get control for big hits without a stiffer everyday ride.
Is installation bolt-on?
Yes. No cutting, welding, or fabrication required. FOX provides a full owner's manual with installation instructions for the rear shock (download from ridefox.com).
Are these rebuildable?
Yes. FOX Factory Race Series shocks are fully rebuildable and serviceable through FOX's service network at service.ridefox.com.
