Important spring note
Springs are not included and must be ordered separately. Spring rate and free length must match the vehicle, suspension travel, target ride height, and intended use. Contact ZEVcentric before ordering so the correct spring options and lengths can be selected.
Installation and setup
This is a competition-oriented suspension component. Professional installation, corner balancing, and a four-wheel alignment are recommended.
