Product Highlights
COIL SPRINGS
Old Man Emu coil springs are designed for each vehicle, using state-of-the-art micro-alloyed spring steel to ensure superior resistance to sagging and corrosion. Finished in a durable, hard-wearing matte black powder coat this new line of coil springs is meant specifically for the Nitrocharger Plus and MT64 line.
Further fine tuning is achieved when the springs are matched to a corresponding set of Old Man Emu shock absorbers and struts, delivering a fully integrated system designed specifically to suit your vehicle.

VERIFY FITMENT
A new range of coils (4xxx series) has been developed to suit the adjustable coil seat on the Nitrocharger Plus struts.
NOTE: These new coil springs are not cross-compatible with Nitrocharger Sport struts or OE struts. (Non-coil over applications continue to use the existing range of Old Man Emu coils).
