Lock Down Your Alignment with the SPL Parts 350Z/G35 Eccentric Lockout Kit

The Nissan 350Z and Infiniti G35 are known for their performance capabilities, but like many performance cars, their stock alignment hardware can be a weak point. The factory eccentric bolts used for minor camber and toe adjustments are prone to slipping under the high cornering loads these cars can generate. This leads to unpredictable alignment changes and compromised handling. The SPL Parts Eccentric Lockout (EL) kit is the definitive solution to ensure your alignment remains precisely where you set it.

Engineered for Precision and Durability

This kit replaces the stock eccentric bolts with precision-machined T6061 aluminum lockout plates. These plates are paired with high-strength, CAD-plated Grade 10.9 hardware, creating a rigid, zero-slip connection that maintains your suspension geometry under extreme conditions. This ensures consistent grip and predictable handling, whether you're on the street, track, or autocross course. Please note that adjustable control arms are required to perform alignment adjustments after installation of this kit.

Vehicle Fitment:

  • 2003-2008 Nissan 350Z (Z33)
  • 2003-2007 Infiniti G35 Coupe (V35)
  • 2003-2006 Infiniti G35 Sedan (V35)

Key Features and Benefits:

  • Eliminates Alignment Shift: Locks toe and camber settings securely.
  • Prevents Slippage: Replaces the weak factory eccentric bolts.
  • Premium Materials: Utilizes T6061 aluminum lockout plates and Grade 10.9 hardware.
  • Complete Kit: Includes all necessary hardware for both camber and toe arms.
  • Made in USA: Guarantees high-quality manufacturing and durability.
  • Essential for Performance: Maintains alignment consistency under load.

For 350Z and G35 owners seeking ultimate alignment control and confidence, the SPL Parts Eccentric Lockout Kit is a must-have upgrade. Experience the difference of a locked-in alignment with GGCRACING.
