Galvanised Parallel Landcruiser Disc Rotor

This Galvanised Parallel Land Cruiser Disc Rotor is a premium, corrosion-resistant braking solution designed for heavy-duty trailers and boat trailers. Specifically engineered for Parallel axles, this rotor features the popular 6-stud Land Cruiser bolt pattern, offering maximum durability in harsh marine and off-road environments.

Product Overview

Upgrade your trailer’s braking system with a rotor built to last. The hot-dipped galvanised finish provides an industry-leading barrier against rust and saltwater corrosion, making it the ideal choice for boat trailers that are frequently submerged. The “Parallel” configuration uses the same size bearing for both the inner and outer positions, providing increased strength and simplified maintenance for 1,600 kg-rated axles.

Key Features

  • Superior Corrosion Protection: Fully galvanised coating protects the non-contact surfaces of the rotor from rust, ensuring longevity in saltwater environments.
  • Parallel Bearing Setup: Designed for high-load capacity, utilising the larger Parallel (L68149/11) bearing set for both inner and outer positions.
  • Land Cruiser 6-Stud Pattern: Features the standard 6 x 139.7mm PCD, compatible with most 4WD Land Cruiser-style rims and off-road trailer wheels.
  • Precision Machined: The braking surface is precision-ground to ensure immediate pad bedding and smooth, shudder-free stopping power.

Technical Specifications

  • Bolt Pattern: 6-Stud LandCruiser (139.7mm PCD)
  • Axle Compatibility: Parallel Axles (1,600kg rating)
  • Bearing Requirements: L68149 (Inner) & L68149 (Outer)
  • Material: Heavy-Duty Cast Iron with Hot-Dipped Galvanised Finish
  • Stud Size: 1/2″ UNF (Pre-installed)

Installation Tip

When installing new rotors, always use a fresh set of Parallel bearings and a high-quality marine-grade hub seal. For the best braking performance, ensure your caliper pads are checked for wear and replaced if necessary to prevent scoring the new rotor surface.

Galvanised parallel Land Cruiser disc rotors are used for applications where corrosion resistance is paramount.
