Leaf Spring for Semi-trailers

A ROR leaf spring is a critical suspension component widely used in heavy-duty vehicles such as trucks, commercial fleets, and off-road vehicles. Constructed from high-strength steel or composite materials, these springs consist of multiple layered leaves that flex under load and return to their original shape when unloaded. This design provides exceptional durability, high load-carrying capacity, and reliable performance with minimal maintenance. Thanks to their robust construction and consistent functionality, ROR leaf springs are essential for maintaining vehicle stability, improving ride quality, and supporting heavy payloads across diverse driving conditions.

Lubrication: Periodically apply a lithium-based or silicone grease at the contact points between leaves (especially in multi-leaf setups) to minimize friction, prevent squeaking, and reduce inter-leaf wear.

Visual Inspections: Check monthly for visible cracks, broken leaves, shifted center bolts, or worn bushings. Pay extra attention after off-road use or heavy loading cycles.

Bushing and Shackle Condition: Inspect rubber or polyurethane bushings for dry rot, splitting, or deformation. Replace if cracked or loose to maintain proper axle alignment.

Tighten Fasteners: Ensure U-bolts, shackles, and mounting hardware are torqued to specification during tire rotations or oil changes.

Cleaning: Rinse mud, road salt, and debris from the spring pack regularly—particularly in winter climates—to prevent accelerated corrosion.
