Front Coil Springs 4-Inch Lift LBS Load Rating

The Dobinsons C59-458 coil springs are engineered in Australia to provide a 4-inch lift for the Toyota LandCruiser 70 Series models from 1999 onwards. Designed specifically for the 78 and 79 Series, these front coils are rated for 160-250 LBS of additional accessory weight, making them suitable for setups that include a replacement bumper or winch. Manufactured to stringent ISO9001:2008 international quality standards at their facility in Central Queensland, Australia, these springs utilize ultra-modern design technology. They undergo a high-intensity shot peening process and are heat-treated for enhanced durability and resistance to fatigue. The springs are formed on precision mandrels to ensure precise end configurations and are finished with a durable powder coat. Dobinsons coil springs are fully scragged and load-tested 100% to eliminate subsequent spring sag and ensure they maintain their required specifications over time. The company employs advanced design programs to optimize each spring for maximum working life, especially crucial for variable/progressive rate springs to achieve correct laden and unladen rates for optimal ride comfort and handling. These coils are typically aqua in color.
