Tokico Illumina Adjustable Shocks and Struts is another great innovation from Tokico. This is a completely user-friendly system, which allows fine-tuning the suspensions for different driving environments. You just need a screwdriver to manage this utility product. The internal architecture of this product is quite different from similar products of other companies. Illumina Tokico Adjustable Shocks and Struts use an intricate adjustment system with a unique multi-stage variable piston and valve design to provide an improved performance. The valve system features a five-position bypass shutter-valve and uses simple detents for easy adjustments. This enables five different configurations of simultaneous rebound and compression damping. These versatile features make these shocks ideal for track or street driving.
