ISR Performance Eccentric Lockout Kit - 89-94 Nissan 240sx

Fits 1989-1994 Nissan 240SX (S13).

The ISR Performance Eccentric Lockout Kit (IS-EL-S13) is a critical upgrade for drivers who demand consistent suspension geometry during high-performance driving. While factory eccentric bolts allow for easy alignment adjustments on a street car, they are prone to slipping under the heavy lateral loads experienced during drifting or track use. This slip causes immediate and unwanted changes to your camber or toe settings, compromising handling and tire wear.

This kit replaces the factory eccentric hardware with precision-cut solid lockout plates. By installing these plates, you eliminate the movement at the subframe mounting point. This setup is intended for use with adjustable aftermarket control arms, where alignment fine-tuning is performed via the arm's turnbuckle rather than the bolt. This ensures your alignment stays exactly where you set it, regardless of how hard you push the chassis.

• Prevents alignment slip at the subframe under high cornering loads
• Replaces unreliable OEM eccentric adjustment bolts
• Essential for track-driven and drift-spec S13 chassis
• Designed for use with adjustable camber, toe, or traction arms
• Manufacturer Part Number: IS-EL-S13
