King, Heavy-Duty 2-Inch Lift Coil Springs (Front 250kg / Rear 500kg+), for Nissan Y61

King Springs Heavy-Duty 2-Inch Lift Coils (Extra-Heavy Load)

The King Springs Extra-Heavy Duty (EHD) series is the definitive suspension choice for Nissan Patrol owners who demand maximum load-carrying capacity without compromising on ride height. This specific spring combination is engineered for fully-equipped touring rigs and workhorses, featuring a 250kg front rating and a massive 500kg+ constant rear load rating. These springs are designed to support vehicles fitted with heavy steel bull bars, winches, dual battery systems, rear drawer setups, and long-range fuel tanks, providing a consistent 2-inch (50mm) lift even when fully laden.

Manufactured in Australia from high-tensile X5K micro-alloy steel, these coils are shot-peened and load-tested to ensure they maintain their "memory" and resist sagging over years of heavy use. While standard springs may buckle under the weight of an expedition build, the King EHD series utilizes advanced tapered wire technology to provide a supple initial ride that firms up as the load increases. This ensures your Patrol remains level and stable, whether you are traversing technical mountain passes or towing a heavy off-road camper.

Features

• Optimized 2-Inch Lift: Provides a 50mm height increase to clear obstacles and accommodate larger tire sizes while fully loaded.
