The SPL Parts Rear Eccentric Lockout Kit (Part #SPL EL FRS) is designed to permanently eliminate rear alignment slip caused by factory eccentric bolts. Under high cornering loads, OEM eccentrics can rotate and allow unwanted toe changes. This lockout kit replaces the factory eccentrics with precision lock plates and high-strength hardware to keep your rear alignment exactly where you set it.
Ideal for track-driven cars and aggressive street builds, this kit removes a common failure point while improving rear suspension consistency and predictability.
