Description
Eliminate suspension slap and restore optimal axle tracking on your commercial trailer with this premium rubber and steel spring eye bushing.
Manufactured by Automann, MR5406 is a commercial-grade, heavy-duty suspension bushing designed for high-capacity leaf spring eyes and equalizer assemblies. Constructed with a dual-layer design, it features an inner steel sleeve bonded to a highly resilient, noise-dampening rubber compound casing. This heavy-duty composition allows the trailer suspension to articulate smoothly under intense payload stress, dampening severe road shock and protecting your main chassis frames from premature fatigue cracking.
Fleet Application:
Sun Country Trailers: This specific bushing is the exact factory-spec configuration trusted on Sun Country multi-car transporters, commercial car carrier lines, and low-profile trailers running heavy-duty multi-leaf suspension packages.
Technical Specifications & Fitment:
Inner Diameter (ID): 1.00 Inch
Outer Diameter (OD): 2.06 Inches
Bushing Length: 3.12 Inches
Axle Weight Capacities: Engineered exclusively for 10,000 lbs. Heavy-Duty (10K HD), 12,000 lbs., and 15,000 lbs. commercial trailer axles.
Industry Cross-References: Directly interchanges with Dexter 014-069-00 / 14-69 (individual bushing), Dexter K71-370-00 (bushing service kit), Dayton 321-359, and Automann MR5406.
Performance Features:
High-Durometer Rubber Core: Formulated from dense, automotive-grade rubber that effectively absorbs lateral shifting and severe vertical impact without crushing or taking a permanent deformative set.
Bonded Steel Sleeve: The center metal core accommodates a standard 1" suspension leaf spring pin or shackle bolt, preventing friction wear directly against the elastomer material.
Extended Service Life: Unlike standard polyurethane alternatives, this rubber-and-steel composite naturally resists breakdown from grease, road grime, salt brines, and sub-zero weather conditions.
Perfect Fleet Suspension Fit: Sized perfectly to fit inside 3-inch wide commercial multi-leaf trailer springs, working in close synchronization with your 12K-15K low-profile brake drums.
