ATRO BSH150U Fifth Wheel Bushing Set | Fits Fontaine BSH-150 | Made in USA

High-Performance Suspension Protection | Made in the USA

Product Overview Don't let worn-out rubber bushings compromise your connection or increase your maintenance costs. The ATRO BSH150U is a premium polyurethane replacement for the Fontaine BSH-150 series. While standard rubber bushings are prone to tearing, cracking, and chemical degradation, ATRO’s proprietary polyurethane formula is engineered to handle the extreme vertical and horizontal stresses of heavy-duty hauling.

The ATRO Advantage: Why Polyurethane?

• 4X Service Life: Industry-leading durability that outlasts traditional rubber 4 to 1, significantly lowering your total cost per mile.

• Zero Chemical Breakdown: ATRO polyurethane is 100% resistant to oil, grease, diesel fuel, and road salt—the primary killers of rubber suspension components.

• No "Cold Flow": Unlike cheaper plastics, ATRO material maintains its shape and performance under extreme temperatures and heavy loads.

• Improved Ride Quality: These bushings absorb high-frequency vibrations, protecting your fifth wheel plate and improving driver comfort.
