ORI STX Struts
are nitrogen air shocks fully loaded with high performance features including externally adjustable rebound valving, 3 stage compression stoke with built in hydraulic and mechanical bump stops, and park position tuning for reduced unloading. Each strut can support up to 1,900 lbs. which makes them ideal for lightweight buggies and rock crawlers. On larger vehicles, multiple struts can be installed independently or even interconnected to act as one unit.

To complement the infinitely adjustable spring rate of the ORI STX strut, the internal compression and rebound valving was also designed for fine tuning. Separate shock oil reservoirs for the compression and rebound stroke of the strut allow for the use of different oil viscosity to tune each direction of movement. For additional fine tuning, the 7 position rebound damping dial found near the bottom of the strut can be adjusted on-the-fly.
Built In Bump Stop and Extension Cushion
Not only do ORI STX Struts make sway bars unnecessary, they do away with external bump stops and limiting straps because those features are already built into the struts themselves. The compression stroke of the STX strut features 3 stages made up of standard valving, a hydraulic bump stop, and a secondary mechanical bump stop to soften hard landings. An end-of-stroke cushion keeps the strut safe from damage caused by over-extension.
Unloading and Push-Off Prevention
Another great feature not found on any other shock is the ability to set a rebound park-position to prevent unloading during a hill climb or decent. Unlike coilovers or air springs that will always rebound back to their ride height position, ORI STX Struts can be set with a predetermined rebound park-position that limits the rebound travel of the strut until the weight of the wheels and axles can extend the strut back to ride height.
Custom Tuning and Valving
Filthy Motorsports is an authorized ORI Struts dealer and has the parts, tools, and experience necessary to fine tune your struts to your specific needs. Unlike traditional shocks that only have rebound and compression valving, ORI STX Struts have internal hydraulic bump stops, independent compression and rebound oil, 7 position rebound valving, and 3 stage compression valving that all need to be calibrated, adjusted, and tuned to work together.
ORI Struts are built to last a lifetime of hardcore off-road abuse because they are designed with easy maintenance, rebuilding, and tuning in mind. Filthy Motorsports carries all of the replacement parts and tools you need to repair or rebuild your ORI struts yourself or you can always send them our way and we'll service them for you in the matter of a few days. If you need replacement parts or want to send your struts in for service, simply contact us for details.

Reviewer: Anonymous Person from Superior, WI
Filthy Motorsports helped me tremendously in deciding between going with coilovers or ORIs. In the end I went with ORIs and could not be happier with the product, price, and service. Thank you!
