SPL Parts Eccentric Lockout Kit for select 2007-2025 Nissan 370Z, Z & Infiniti G35, G37 (SPL EL Z34)

Fits select 2007-2025 Nissan 370Z and Z, and Infiniti G35, G37, and Q40. This SPL Parts Eccentric Lockout (EL) kit is designed to solve the common issue of alignment drift during performance driving. On the Nissan Z34 and V36 chassis, factory eccentric bolts used for rear camber and toe adjustments often slip under high cornering loads, causing unpredictable handling and premature tire wear.

By replacing the OE eccentric bolts with these fixed lockout plates, you secure your rear alignment settings permanently. This kit is essential for track-driven vehicles and high-performance street builds. Please note: because these plates eliminate the factory adjustment mechanism, you must have adjustable control arms installed to set your camber and toe specs.
