Description
Isolate harsh road shocks and prevent pin-mount frame wear across your commercial fleet with the genuine Heavy Duty Truck Shock Absorber Mounting Rubber Grommet Bushing. Engineered specifically for heavy commercial truck pin-type shock mounts, cab suspension dampers, frame brackets, and multi-axle freight trailers, this OE-grade elastomeric grommet cushions high-frequency road vibrations and vertical axle oscillation under extreme payloads. Squished rubber faces, hardened elastomer bodies, oil-soaked degradation, or missing grommets cause metallic rattling, severe mounting stud bending, shock absorber eyelet distortion, and uncontrolled chassis vibration. This original mounting rubber grommet bushing solves those suspension noise and fitment failures directly. It features high-durability natural rubber (NR) or EPDM polymer compound, double-tapered self-centering geometry, anti-aging additives, and oil-resistant formulas to deliver whisper-quiet chassis damping, zero mounting pin play, and uncompromised transport reliability.
Technical Parameters
| Category | Specifications & Technical Details |
| Double-Tapered Self-Centering Geometry | We use a double-tapered or lipped matched eyelet structure. When the mounting nut is tightened, it automatically centers the shock absorber eyelet bore with the mounting pin. As a result, clamping force distributes evenly. |
| High-Elasticity Natural Rubber / EPDM Compound | We manufacture the bushing from high-density heavy-duty natural rubber (NR) or EPDM. It delivers excellent elastic recovery and compression permanent deformation resistance. Consequently, it easily absorbs continuous impact. |
| Oil, Chemical & Weather-Resistant Polymer Coating | We blend anti-ozonant agents and oil-resistant chemical additives into the rubber compound. They effectively prevent rubber cracking and hardening caused by road mud, diesel splash, de-icing salt, and high-temperature baking. |
| Optimized Durometer Hardness & Damping Ratio | We precision-tune Shore hardness to the suspension (typically 65–75 Shore A). It effectively isolates high-frequency road noise while providing enough rigidity to prevent shock absorber pin wobble. |
| OEM Precision Injection Molding Tolerances | We match inner bore and outer diameter tolerances strictly to frame mounting pin and shock absorber joint standard dimensions. The bushing locks tightly without sliding. Notably, it completely eliminates mounting bore wear and deformation. |
Applicable Car Brands & Models
Common warning symptoms include:
Rattling or Clunking Noise From Suspension: Loud metallic rattling sounds around frame brackets when driving over rough pavement or expansion joints.
Visible Rubber Splitting or Flattening: The rubber grommets look visibly cracked, squished paper-thin, or partially missing from the shock mounting pin.
Excessive Shock Absorber Play: The shock absorber body can be manually moved or rotated on its mounting stud due to loose, deteriorated rubber.
Bent Mounting Studs: Unprotected metal-on-metal contact causes the shock absorber eyelet to wear down or bend the threaded frame mounting pin.
Premature failure is typically caused by over-tightening the mounting nut (crushing the rubber beyond its elastic limit during installation), oil leakage from nearby hub or engine seals dissolving natural rubber, and continuous overloading under severe off-road conditions.
Yes. Fleet mechanics strongly recommend replacing both upper and lower rubber grommets whenever changing or servicing a pin-mount shock absorber. Reusing old, crushed grommets with a new shock absorber leads to alignment play and accelerates seal failure inside the new shock.
Our 1-year warranty covers all rubber splitting, premature elastomer hardening, dimensional molding defects, severe compression set, and manufacturing flaws under normal operating conditions. If a grommet fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
