Overview:
The Upper Load Pad is a critical suspension component engineered for use in heavy-duty Mack trucks. Positioned at the top of the suspension stack (often on Camelback or similar suspensions), this pad functions as a cushioning and load-distributing element between the truck’s axle housing and frame or spring assembly. It helps manage vertical load forces, minimize metal-on-metal contact, and reduce road shock transmission.
Key Features:
✅ High-Density Rubber Construction:
- Manufactured from durable, heavy-duty rubber formulated to handle extreme weight and constant flexing.
- Designed to withstand high loads, frequent compression, and a wide range of temperatures without cracking or breaking down.
✅ Precision Fit for Mack Trucks:
- Engineered specifically to fit Mack suspension systems, especially models equipped with Camelback or walking beam suspensions.
- Matches OEM specifications to ensure proper alignment and secure mounting.
✅ Shock and Vibration Absorption:
- Acts as a buffer between major suspension components to absorb road shocks, impacts, and harsh vibrations.
- Helps protect the chassis and drivetrain from wear and tear caused by continuous heavy-duty operation.
✅ Noise Reduction:
- Reduces metal-on-metal contact, which lowers operational noise, especially under load or on rough surfaces.
