ENDURO AND ALL-MOUNTAIN COIL SHOCK
The Mod coil shock is built for sensitivity, control and reliability. 
Sensitivity
Coil shocks excel at initial-touch sensitivity. The Mod’s high oil flow damping circuit and large volume bladder oil reservoir give fine levels of grip. They also allow the shock to run cooler, giving a consistent feel on long descents.
Control
The mid to end stroke is controlled by Formula’s Compression Tuning System, or CTS. These are rider-changeable valves that increase or decrease the hydraulic flow within the shock. CTS allows you to tune the shock’s characteristics to the way you ride. 
A simple polyurethane bump-stop prevents harsh bottom outs without the need for complex hydraulics.
Reliability
With major service intervals every 200 hours the Mod is reliable and can be serviced at home.
 
* Note: included in the sale of the shock is the shock, 3x CTS valve (gold, orange and green), shock pump. Spring and hardware available seperately.
 
A yoke mount compatible version of the Mod coil shock is now available.
A yoke mount, also called a clevis mount, increases side-loading on the shock. Air shocks can handle this load, thanks to their large diameter shafts and bodies, but coil shocks can’t, leading to failures. Many manufacturers advise against using coil shocks on frames with a yoke mount.
 
The latest version of Formula’s Mod is specifically designed to better handle side-loading, offering a reliable coil shock option for frames with a yoke mount.
 
Performance and weight are the same as the standard Mod. Major service intervals are reduced from 200 hours to 125 hours.
 
A standard Mod shock can be upgraded to be yoke compatible by a Formula Service center.
