Key Features & Benefits
- 8mm standard thickness — the most common axle pad thickness for Australian light to medium duty trailers, providing the correct clearance between spring and axle.
- Even load distribution — spreads the U-bolt clamping force across a wider area, preventing the spring from digging into or deforming the axle surface over time.
- Sold as a pair — two pads per pack so you can service both spring seats on a single-axle trailer.
- Essential suspension component — worn or missing axle pads allow the spring to shift on the axle, causing misalignment, uneven tyre wear and unstable towing.
When to Use These Pads
Replace axle pads whenever you rebuild or service the trailer suspension. They are a low-cost component that prevents expensive axle and spring damage. Use R5510 with the appropriate U-bolts (R5602, R5604, R5606 or R5608 depending on your axle size and shape) and R1419A fish plates for a complete suspension assembly.
