Traction Gas Springs, TSNI models, operate in reverse of standard struts. These models operate in extension (tension) rather than compression. Nitride protection affords corrosion protection. Complete parts are black in appearance. End fittings are supplied as indicated in the data table, but Associated Spring RAYMOND offers a complete line of end fittings to suit your application. If your OEM or aftermarket application is in need of a custom gas spring, accessory, or functional assembly consider our engineered solution services.
