Eibach PRO-SPACER 25 mm Wheel Spacer Kit – Ford Mustang / Ford Explorer – 5x114.3 Bolt Pattern – Black Anodized Aluminum

Give your Ford the confident, planted stance it deserves with the Eibach PRO-SPACER 25 mm kit (Part # S90-4-20-041-6)—engineered to widen your track width for sharper handling, improved stability, and a flush fender-to-wheel fit. Designed specifically for Ford Mustang and Ford Explorer platforms, these spacers push the wheels outward 25 mm per side, transforming both appearance and cornering dynamics without altering ride quality or geometry.

Machined from 6061-T6 aircraft-grade aluminum, the PRO-SPACER series combines lightweight precision with race-ready strength, meeting the same standards used in professional motorsport applications.

Precision Engineering for Performance

Eibach’s PRO-SPACERs are more than cosmetic upgrades—they are functional suspension geometry enhancers. Increasing track width improves weight distribution and roll resistance, creating a flatter, more composed cornering attitude.

Performance Advantages:

• Improved Grip & Stability: Wider track width means greater lateral traction through corners.

• Enhanced Steering Feedback: Sharper turn-in and more predictable road feel.

• Perfect Flush Fitment: Eliminates sunken wheel appearance for a true performance stance.

• Optimized Clearance: Corrects offset when fitting aftermarket wheels or brake upgrades.

Every Eibach spacer is CNC-machined to micron-level tolerances for hub-centric fitment and vibration-free operation—ensuring your Mustang or Explorer handles as smoothly as it looks.

Engineered with 6061-T6 Aircraft Aluminum

Eibach uses aerospace-grade 6061-T6 billet aluminum for maximum tensile strength and minimal unsprung weight. This high-strength material is both lightweight and corrosion-resistant, making it ideal for street and track use alike.

Technical Highlights:

• Material: 6061-T6 Aircraft-Grade Aluminum

• Finish: Black Anodized for Durability & Corrosion Resistance

• Thickness: 20 mm per side (40 mm total track increase)

• Design: Hub-Centric for Vibration-Free Fitment

• Hardware: Includes Extended Lug Nuts and Washers

• Warranty: Limited Lifetime Coverage

These spacers undergo extensive fatigue and tensile testing to ensure long-term performance under dynamic loads and temperature fluctuations—meeting Eibach’s stringent quality standards established over 70 years of motorsport engineering.

Fitment Applications

Designed exclusively for Ford 5x114.3 platforms, this kit fits a wide range of Mustang and Explorer models.

Vehicle Compatibility:

• Ford Mustang (2015 – 2025)

  • EcoBoost, GT, Mach 1, and Shelby variants (excludes GT500 carbon package)

• Ford Explorer (2011 – 2025)

  • Base, XLT, ST, Limited, and Platinum models

⚠️ Fitment Note: These 20 mm spacers require wheels with back-side cut-outs to accommodate factory stud protrusion. Always confirm stud length and hub depth before installation.

Technical Specifications

Lightweight Strength Meets Functional Design

Eibach’s billet construction provides superior strength-to-weight ratio over steel alternatives, ensuring your suspension responds faster to road inputs while reducing rotational mass. Hub-centric alignment maintains true balance, eliminating vibration and minimizing wheel-bearing stress.

Advantages Over Steel Spacers:

• Up to 50% lighter for better unsprung weight management.

• No corrosion or oxidation under harsh conditions.

• CNC flatness ensures full contact and load distribution.

• Anodized finish for long-term aesthetic and structural integrity.

Installation & Setup

Installation is straightforward and requires only basic hand tools and a torque wrench.

Quick Steps:

1. Clean hub and wheel mating surfaces.

2. Mount Eibach PRO-SPACER onto hub and hand-tighten hardware.

3. Torque in a cross pattern to factory specifications.

4. Reinstall wheel and torque lugs to OEM values.

5. Recheck torque after 50–100 miles.

💡 Tip: Professional installation recommended for alignment verification and safety assurance.

Real-World Results

Form and Function Unified:

• Visually flush stance aligned to fenders.
