Our FOX 2.5 Factory DSC kit is a high-performance suspension upgrade for Toyota 4-Runner/FJ. It includes FOX's 2.5 Factory Series front coilovers with DSC compression adjusters, which offer precise tuning and increased oil capacity for better performance. The kit also features upper arms that address limitations of stock arms, improving wheel travel and correcting suspension geometry. In the rear, we provide FOX's 2.5 Factory Series DSC remote res. shocks, which offer increased oil capacity and control. These shocks can be used with stock coil springs or our Camburg coil springs for optimal wheel travel. Please note that modifications may be required to eliminate tire rubbing depending on various factors such as wheel size, offset/backspacing, and suspension components.
