Front Lifted Coil Springs

The Dobinsons C59-314 coil springs are engineered to provide specific lift heights and support various load requirements for a wide range of 4x4 vehicles, including Toyota 4Runner, Tacoma, FJ Cruiser, Lexus GX460/GX470, Isuzu D-Max, and Mazda BT-50 models. The exact lift and load capacity vary by application; for example, they offer a 2.5" lift for a 2003-2009 4Runner V8 with stock weight, and a 3.0-3.25" lift for a 2009-2024 4Runner V6 with a 110lb load. These springs feature a free height of 405mm and a 17mm wire diameter, with a spring rate of 586 LBF/IN. They are designed to be comparable to OME 2888 coils. It is crucial to match the specified constant load to the vehicle's requirements to achieve the intended lift height and prevent poor driving conditions. Constant weight typically includes accessories like bumpers, winches, auxiliary batteries, and heavy-duty compressors. Dobinsons manufactures these springs in Australia, adhering to ISO9001:2008 quality standards. The manufacturing process involves load testing, scragging, fatigue testing, and hardness testing to ensure durability and performance. They are designed using advanced software to optimize ride comfort and handling, especially for variable/progressive rate springs. These C59-314 coils are designed to work with Dobinsons front struts, though installation instructions are also available for use with other struts. Important fitment notes indicate that these springs are not compatible with Bilstein 6110 struts. The top of the springs are flat, with a pigtail at the bottom. Proper installation and matching the springs to the vehicle's constant load are essential for optimal performance and achieving the advertised lift heights.
