Front Coil Springs

The Dobinsons C59-748 coil springs are a premium upgrade for the Toyota 4Runner TRD Pro equipped with Bilstein and Fox struts. Designed and manufactured in Australia to ISO9001:2008 international quality standards, these springs offer a direct 1.0" lift over stock height simply by changing the coils, with no other modifications required prior to a necessary alignment. They are constructed using state-of-the-art heat treatment and high-intensity shot peening for maximum durability and performance. Each coil is formed on precision mandrels and features precise end configurations for a perfect fit. They undergo a rigorous process including being fully scragged and load-tested to eliminate subsequent spring sag, ensuring they maintain their specifications over time. The springs also feature a durable powder coat finish for added protection against the elements. Dobinsons utilizes advanced design programs to ensure each spring meets or exceeds design requirements for maximum working life. This is particularly crucial for their variable/progressive rate springs, ensuring optimal ride comfort and handling whether the vehicle is laden or unladen.
