FOX DHX

The right size shock for your bike is determined by its eye-to-eye length (distance between shock eyelets) and stroke (distance the shock compresses) that fits your bike’s frame and suspension design. E.g. a 210x52.5mm shock has a 210mm eye-to-eye length and 52.5mm stroke.

FOX shocks also require specific mounting hardware that bolts the shock to your bike’s frame (available from us). Both shock size and hardware information should be available in the specs section on your bike brand’s website, or can be measured.

FOX coil shocks require a spring, which is purchased separately. Springs are available in black powder coated steel or orange Super Light Steel (SLS) in 50lb/inch and 25lb/inch spring rates respectively.

Choosing the right spring rate comes down to several factors including rider weight, the bike’s suspension design and personal preference.

We suggest using our online spring calculator to find a starting point.

FOX offers three different series of its aftermarket shocks. Note that not all shocks have every series available to purchase.
