The ATRO FW99-32109 is a high-performance polyurethane bushing kit designed specifically for Fontaine LWS, MTB, and ATB Series fifth wheels.
Standard rubber bushings are the weak link in your fifth wheel assembly—they compress, crack, and "slop out" under the immense pressure of trailer articulation. ATRO’s proprietary polyurethane formula is engineered to maintain its shape and pivot tension, eliminating the annoying "clunk" and excessive movement that occurs when rubber fails.
Zero Deformation: Unlike rubber, these bushings will not take a permanent "set" or flatten under heavy vertical loads.
Chemical & UV Resistance: Completely impervious to 5th wheel grease, diesel fuel, road salt, and cleaning solvents.
Maintenance-Free Durability: Designed to outlast OEM rubber bushings by a 3-to-1 margin, reducing your long-term maintenance costs and downtime.
Smoother Pivoting: Provides consistent, controlled movement for better trailer handling and reduced wear on the mounting brackets.
