Description
8400 Double Adjustable Shock
The 8400 Double Adjustable Shock gives you a wide range of adjustability that helps tune your car for a wide variety of track conditions. This saves you time by not having to re-valve your shock when the track changes. It also saves you money by limiting the number of shocks needed in your inventory. The 8400 comes with 20 different compression and 20–80 rebound settings (depending on eyelet option). This allows you to fine-tune your suspension to meet your needs.
Also available in a 3-way adjustment, this option is typically run on the RR. This gives you a wider tuning window. Commonly, the RR is an area of feel for the driver. The separate high and low-speed compression adjustability really allows you to tune for RR support while maximizing grip.
