Reliable Kenworth T660 Hood Struts and Other Heavy Trucks

Easier, Safer Hood And Tailgate Lift

High-strength gas struts provide powerful lift support, allowing heavy truck hoods, tailgates, and cargo doors to open smoothly and stay securely in place, minimizing accidental drops, injuries, or damage.

Durable & Versatile Design

Featuring standard ball or metal hinge connectors, heavy-duty struts can be quickly replaced without special tools. Their simple design requires minimal maintenance, reducing overall operating costs.

Durable and Reliable in Harsh Conditions

With thick steel cylinders, corrosion-resistant coatings, and high-quality seals, these struts perform reliably in extreme temperatures, dust, rain, and snow, offering a longer lifespan than standard struts.

Reliable Kenworth T660 hood struts are designed to provide strong, stable, and safe hood support for heavy-duty trucks operating in demanding environments. Built with high-strength steel cylinders and corrosion-resistant piston rods, these hood struts ensure smooth lifting and controlled lowering of the hood. They help reduce operator effort during inspections and maintenance, improving safety and efficiency while minimizing the risk of accidental hood drop in daily heavy truck operations.

In addition to the Kenworth T660, these reliable hood struts are suitable for other heavy trucks that require durable and long-lasting lift support solutions. Precision-engineered sealing systems ensure consistent performance under extreme temperatures, vibration, and frequent use. Easy installation and direct-fit design make them ideal for replacement or upgrade, delivering dependable performance, extended service life, and reduced maintenance costs for fleets and individual truck owners alike.
