4Runner 2003-2024 Toyota - Fox Factory Race Series 2.5 Internal Bypass Coil-Over Kit (2-3" Front Lift)

Take your Toyota 4Runner’s suspension to the next level with FOX's 883-06-227 Factory Race Series 2.5 Internal Bypass coilover shocks. Designed for serious off-road performance, this bolt-on upgrade delivers precision damping and unmatched terrain control. The patented Internal Bypass technology ensures position- and velocity-sensitive performance, offering a smooth ride in the travel zone with increased damping as you push toward full compression or extension.

Dual Speed Compression (DSC) adjusters allow you to fine-tune ride quality for various loads and driving conditions, while external reservoirs keep oil cool and performance consistent during high-speed off-road driving. The 2.5-inch aluminum bodies are treated with a Type III anodized finish for superior resistance to wear and corrosion. Whether you're bombing through desert trails or crawling over rocks, these shocks provide the progressive support and confidence you need to handle rugged terrain with comfort and control.

DSC Adjusters

Each reservoir has a dual-speed compression (DSC) adjuster that allows you to dial in high-speed and low-speed compression settings. With the DSC adjusters, you can swiftly tailor your coilovers to suit different loads, environmental conditions, and your preferred driving style. Adjust is made simply by turning the low or speed dials to your desired settings (10 low-speed settings, 12 high-speed settings). Meanwhile, the high-flow piston ensures stability across various terrains. FOX shocks are meticulously engineered to accommodate multiple activities, allowing you to unlock your truck's full potential on your next adventure.
