Keep your commercial rigs tracking straight and eliminate frequent suspension failures with this premium, American-made polyurethane straddle bushing from ATRO Engineered Systems. This component features ATRO's specialized High Articulation chemical formulation, engineered to handle intense suspension twisting and heavy torsional loads that quickly shred standard rubber bushings.
Crafted from solid heavy-duty polyurethane, it is entirely immune to oil, grease, road chemicals, and environmental dry-rotting, making it the ultimate maintenance-free upgrade for your fleet.
Vehicle System Fitment: Designed exclusively for Kenworth Airglide 200, 400, 460, and 690 suspension torque rods (specifically engineered for rod part numbers K195-474 and K195-472).
Rotational Constraint: This bushing is structurally fixed and does NOT rotate.
