ISR Performance Eccentric Lockout Kit

2003–2008 Nissan 350Z

Part #: IS-EL-S14

Overview

The ISR Performance Eccentric Lockout Kit is designed specifically for Nissan 350Z models from 2003 to 2008. This high-quality upgrade addresses a common issue with factory eccentric bolts used for camber and toe adjustments. Under high cornering loads, these factory bolts can slip, leading to unwanted changes in your rear alignment. This can affect handling, tire wear, and overall driving confidence. The ISR lockout kit eliminates this problem by securely locking the adjustment plates in place, ensuring your alignment settings remain consistent and reliable.

Whether you're a performance enthusiast, a track day driver, or someone who demands precise alignment for spirited driving, this lockout kit provides a simple yet effective solution. By preventing unwanted camber and toe shifts, you'll enjoy improved handling stability and more predictable cornering behavior. It's an essential upgrade for those who have already invested in adjustable control arms and want to maximize their alignment accuracy and consistency.

Key Features

The ISR Performance Eccentric Lockout Kit offers several key features that enhance your Nissan 350Z's suspension setup:

• Machined from durable stainless steel, ensuring long-lasting strength and resistance to corrosion in various driving conditions.
• Supplied with grade 10.9 hardened steel hardware for secure installation and reliable performance under high loads.
• Designed to replace factory eccentric bolts, effectively locking the camber and toe adjustment plates in their set positions.
• Compatible with vehicles equipped with adjustable control arms, allowing for precise alignment adjustments after installation.
• Manufactured with high-precision machining to ensure perfect fitment and ease of installation.
• Helps maintain consistent rear alignment, improving handling, tire wear, and overall vehicle stability during aggressive driving or spirited cornering.

Construction & Design

The ISR lockout plates are crafted from high-grade stainless steel, providing excellent strength and corrosion resistance. The design features precise machining to ensure a perfect fit with the factory components and aftermarket control arms. The lockout plates replace the factory eccentric bolts, which are prone to slipping under high loads, with a more secure locking mechanism. This design eliminates the risk of alignment shifts caused by factory bolt slippage, especially during aggressive driving or track use. The hardware included is grade 10.9, ensuring that the installation remains secure over time and under demanding conditions.

Performance & Benefits

By installing the ISR Performance Eccentric Lockout Kit, you will experience improved handling consistency and confidence in your Nissan 350Z. The lockout prevents the factory eccentric bolts from slipping, maintaining your desired camber and toe settings. This stability translates to more predictable cornering, better tire wear, and enhanced overall vehicle control. While the kit does not directly increase horsepower or torque, it plays a crucial role in optimizing your suspension setup for maximum performance and reliability.

Installation & Fitment

The installation process is straightforward for those familiar with suspension components. The kit replaces the factory eccentric bolts with machined stainless steel lockout plates, which are then secured with the supplied grade 10.9 hardware. It is recommended to have adjustable control arms installed beforehand, as the lockout kit does not provide adjustment capability itself. No cutting, drilling, or complex modifications are required, making this a bolt-on upgrade that can be completed with basic tools. Proper alignment should be checked and adjusted after installation to ensure optimal handling and tire wear.
