Upgrade your trailer or truck suspension stability and stop recurring bushing walk-out with the ATRO PL1119 Premium Polyurethane Torque Rod Bushing. Proudly Made in the USA, this heavy-duty suspension component is engineered specifically to replace short-lived factory rubber bushings on high-mileage vocational fleets, commercial trailers, and owner-operator rigs.
Standard rubber bushings quickly distort, soften, and walk out of the torque rod eyelet under heavy payload shifting and constant exposure to oil, grease, and road contaminants. ATRO’s proprietary polyurethane formula is chemically engineered to remain completely immune to these fluids while offering unmatched tear strength. The PL1119 features an advanced 2-piece design engineered with added outer rims that physically lock and retain the bushing firmly inside the rod eyelet. Designed to fit popular Hutchens 7700/9700 Four-Spring trailer suspensions and Watson & Chalin truck suspensions, this kit ensures crisp tracking, reduced downtime, and an extended service life.
Note: This high-performance 2-piece polyurethane design differs in physical appearance from the original OEM solid rubber style but serves as a direct drop-in performance upgrade.
Anti-Walkout Outer Rims: Built-in structural outer rims are added to the layout to physically retain the bushing inside the rod, preventing frustrating shifting and migration.
2-Piece Split Configuration: Allows for quick, convenient installation in the shop without requiring the extreme press force needed for single-piece alternatives.
Premium Polyurethane Chemistry: Outlasts standard rubber replacements by completely resisting dry rot, ozone cracking, grease saturation, and crushing forces.
Broad Vocational Coverage: Universally replaces parts on massive suspension platforms including Hutchens, Trailmobile, and Watson & Chalin setups.
