ARB / OME Front Coil Spring Set 03-23 Toyota 4Runner

Upgrade the front suspension on your Toyota 4Runner with the ARB Old Man Emu 4001 Front Coil Spring Set. Old Man Emu coil springs are designed around vehicle-specific load requirements and intended use, helping improve ride control while providing a durable suspension upgrade for street, trail, overland, and off-road builds.

ARB manufactures these springs from X5K micro-alloyed spring steel for strength, durability, sag resistance, and corrosion resistance. The coils are double-scragged to reduce spring stress and help improve spring life, formed on computer-precision mandrels for consistency, and finished in a hard-wearing matte black powder coat.

This listing is for the front coil spring set only. Shocks, struts, rear springs, upper control arms, and other suspension components are not included unless stated separately.
