Link Mfg. Unveils Enhanced Bushings and Torque Rods for Fire and Rescue Vehicles

Link Mfg., Ltd., a recognized leader in specialty-engineered suspensions, has recently announced its latest innovation tailored specifically for fire and rescue applications. As the demands on fire apparatus increase, so does the need for robust suspension systems that can withstand the rigorous environments these vehicles operate in. On October 21, 2025, Link introduced a new line of severe-duty bushings and torque rods designed for the Air Link suspension systems rated between 46,000 and 52,000 pounds.

Superior Durability for Critical Operations

The new bushings utilize a proprietary rubber compound combined with an optimized geometry. This has been custom-designed to extend the longevity of components in highly demanding situations typical in fire service applications. According to Chris English, managing director of Link Suspensions of Canada, this innovative design significantly addresses real-world performance challenges faced by fire departments. Extensive collaboration and validation testing were integral in creating a product that elevates durability during extreme braking, acceleration, and articulation events common in emergency operations.

Innovative Design Features

One of the standout features of the new bushings is their double-bonded construction. The rubber is directly bonded to both inner and outer metal surfaces, effectively eliminating friction and minimizing wear during operation. This modification helps maintain optimal clamp load over the entire service life of the bushing, enhancing reliability at crucial pivot points, including axle end connections and walking beam centers. More importantly, Link is extending the warranty on these upgraded bushings from one year to two years, reflecting their confidence in the new design and providing fire departments with lower lifecycle costs and increased operational reliability.

Seamless Integration and Availability

The new bushings are intended to be integrated as standard equipment in all Air Link suspensions rated within the specified weight range starting with production units delivered after October 31, 2025. For those looking to retrofit existing vehicles, aftermarket service kits for the new bushings and torque rods are available for immediate order. Notably, these bushings maintain identical form, fit, and function with previous designs, ensuring that no new training or installation procedures are required, allowing for smooth transitions in maintenance practices.

Introducing Torque Rods for Enhanced Performance

In conjunction with the bushings, Link also announced severe-duty torque rods engineered for suspensions rated from 46,000 to 60,000 lbs. These torque rods significantly improve the positioning of axles during both acceleration and braking, featuring permanently lubricated spherical ball ends to eliminate the hassle of regular maintenance. Their double-adjustable design allows for precise length adjustments, and when paired with the new bushing technology, these rods further bolster the overall integrity of pivot connections.

The importance of having durable components for fire and rescue vehicles cannot be overstated, as operational reliability is critical during emergencies. Link's commitment to excellence is evident in these advancements, cementing its reputation in the sector.

Future Developments on the Horizon

Link Mfg. is also set to further enhance its offerings by developing severe-duty bushings for Air Link suspensions rated at 60,000 pounds and above, with an expected release in early 2026. This aligns with the company's ongoing goal to innovate and meet the evolving needs of heavy-duty vehicle operators.
