Old Man Emu coil springs are part of an integrated 4WD suspension system designed to handle the demands of remote area travel where fuel, water, vehicle spares, and safety equipment place significant strain on suspension components. While ride height increases are achieved, the primary emphasis is placed on ride control improvements. For optimal performance, these springs can be paired with corresponding Old Man Emu shock absorbers to create a fully integrated suspension system tailored to your specific vehicle and load requirements.

Backed by a 3-year warranty, these springs are designed for direct replacement of OE components with no custom installation required.
