The Multiquip 505985 Shockmount 54 x 33-70SH Frame A is a genuine OEM shockmount designed for AR13HC, AR13HA/HAR, AR13H, and AR13D asphalt ride-on rollers. As a direct Multiquip OEM component, 505985 is manufactured to the same specification as the original part, ensuring a correct fit within the Frame A mounting position. This shockmount is the right call when servicing any AR13-series roller that shows signs of vibration transfer, frame fatigue, or worn isolation hardware.
Key Features
- Genuine OEM Isolation Material: — Engineered to the exact rubber compound and durometer rating of the original, maintaining the correct vibration dampening behavior specific to the AR13 roller frame.
- Frame A Position Fit: — Dimensioned at 54 x 33-70SH to drop into the Frame A mounting location without alteration, aligning correctly with existing hardware and mounting surfaces.
- AR13-Series Compatibility: — Confirmed fitment for AR13HC, AR13HA/HAR, AR13H, and AR13D asphalt ride-on rollers — cover the full AR13 lineup with a single part number.
- Protects Frame Integrity: — A functioning shockmount absorbs and isolates drum vibration from the frame; a worn or collapsed mount transfers excessive shock load directly to the chassis, accelerating structural wear.
- Operator Comfort and Control: — Proper shockmount condition directly affects how much vibration reaches the operator platform and steering system, supporting smooth, controlled roller operation on asphalt passes.
A shockmount is a rubber-bonded isolation component that sits between the vibrating drum assembly and the main frame of the roller, absorbing and dampening the high-frequency vibration generated during compaction. By isolating this vibration, the shockmount prevents it from transmitting through the chassis, protecting frame welds, fasteners, and operator controls from premature fatigue. When a shockmount hardens, cracks, or collapses, vibration bypasses the isolation layer entirely — leading to increased operator fatigue, loosening of frame hardware, and potential structural damage to the roller body over time.
