Overview

The SPL Parts Eccentric Lockout (EL) kit is designed to eliminate the stock eccentric bolts in your Nissan 350Z or Infiniti G35. These stock bolts can slip under high cornering loads, affecting your rear alignment. The EL kit keeps your rear alignment precisely where you set it. It is constructed from CNC-machined T6061 aluminum with CAD plated grade 10.9 hardware for a zero-slip connection. The kit includes washers and bolts for both camber and toe arms, and is sold as a complete kit for one car.
Show original supplier description
The SPL Parts 350Z/G35 Eccentric Lockout (EL) kit replaces the factory eccentric bolts that are prone to slipping under load, which can alter your vehicle's rear alignment. By eliminating these stock bolts, the EL kit ensures that your alignment settings remain stable, even under aggressive driving conditions. They are paired with CAD plated grade 10.9 hardware, guaranteeing a secure, zero-slip connection. The kit is comprehensive, including all necessary washers and bolts for both camber and toe arms, and is sold as a complete set for a single vehicle. Installation requires that you already have adjustable control arms, as these are necessary for adjusting camber and toe after the stock eccentric bolts are removed. This kit is made in the USA and is compatible with the 2003-2008 Nissan 350Z (Z33), the 2003-2006 Infiniti G35 Sedan (V35), and the 2003-2007 Infiniti G35 Coupe (V35). Always confirm fitment with your specific vehicle details before purchase to ensure compatibility and avoid potential returns or restocking fees.
