These struts are built using heavy-duty boxed sheet metal, giving your suspension added strength and rigidity where it matters most. The design is more than just functional—it’s sharp and aggressive, adding a custom touch to your truck’s undercarriage. Finished in a semi-gloss black powder coat, they not only look the part but hold up well against the elements, rocks, and road grime. Built for Performance, Designed to Last These compression struts aren’t just about looks. They play a key role in maintaining proper front suspension geometry on lifted trucks, helping to reduce stress on the frame and steering components. That means better stability, improved handling, and added confidence whether you’re hauling heavy loads, heading off-road, or just cruising on the highway. Each set is made right here in the USA and backed by Cognito’s limited lifetime warranty, so you can install them knowing they’re built to handle the long haul. If you're aiming for clean looks with real structural benefits, this is a solid upgrade that won’t let you down.
