Product Description

The SPL Parts SPL RTAEL S550 Adjustable Rear Toe Arms with Eccentric Lockouts are a high-performance rear suspension upgrade engineered specifically for the 2015-2026 Ford Mustang S550. These adjustable toe arms replace the factory rear toe links and provide a greater range of adjustment to correct toe settings, especially after lowering, raising, or modifying your suspension. By eliminating bushing deflection and adding precision adjustment capability, this kit enhances rear stability, handling response, and tire wear characteristics, whether on the street or track. 

A key advantage of this kit is the included eccentric lockouts, which replace the stock eccentric bolts that are prone to slipping under high cornering loads, causing unintended alignment changes. Machined from lightweight, high-strength materials with PTFE-lined FK bearings and premium titanium hardware, these rear toe arms offer durable, precise suspension enhancement designed to keep your alignment settings locked in place during aggressive driving. Professional installation and a post-installation wheel alignment are recommended to ensure optimal performance and handling precision.
