Safety Information

WARNING: Improper installation, incompatibility, or failure to re-torque hardware can cause loss of wheel and result in serious accident, injury, or death. Always follow manufacturer specifications and consult a professional if unsure.

• Ensure the vehicle is parked on a flat, stable surface and the parking brake is engaged.
• Use appropriate safety equipment, including jack stands, wheel chocks, and personal protective equipment (gloves, eye protection).
• Never work under a vehicle supported only by a jack. Always use jack stands.
• Do not use an impact wrench for final tightening of lug nuts on the wheel spacers or the wheel itself. Use a torque wrench.
• Verify proper fitment and clearance before driving.
• Re-torque all lug nuts after the first 50-100 miles of driving, and again every 2000-3000 miles.

Product Overview and Components

ECCPP Wheel Spacers are precision-engineered from T6 billet aluminum for durability and lightweight performance. Each spacer comes with heat-treated and hardened 10.9 grade bolts pre-installed.

Step-by-Step Installation

1. Prepare the Vehicle:

   Park the vehicle on a level, firm surface. Engage the parking brake. Loosen the lug nuts on the wheel you intend to work on using a lug wrench. Do not remove them completely yet.

   

   Figure 7: Overview of Installation Steps and Required Tools

   This image provides a summary of the installation process and illustrates the basic tools required, such as a wrench, jack, and brush.

2. Lift the Vehicle:

   Place a jack under the vehicle's frame near the wheel. Lift the vehicle until the wheel is off the ground. Secure the vehicle with jack stands for safety.

3. Remove the Wheel:

   Completely remove the loosened lug nuts and carefully take off the wheel. Set it aside in a safe location.

4. Clean the Hub Surface:

   Thoroughly clean the vehicle's hub surface to remove any rust, dirt, or debris. This ensures a flush fit for the wheel spacer. Use a wire brush and rust neutralizer if necessary.

   This image shows a person cleaning the vehicle's hub and brake rotor, emphasizing the importance of removing rust for proper spacer fitment.

5. Mount the Wheel Spacer:

   Place the wheel spacer onto the vehicle's hub, aligning the holes with the vehicle's studs. Use the provided lug nuts to hand-tighten the spacer to the vehicle's hub. Ensure the spacer sits flush against the hub.

6. Torque the Spacer Lug Nuts:

   Using a torque wrench, tighten the spacer lug nuts to the manufacturer's specified torque. Refer to the torque specifications table below. Tighten in a star pattern to ensure even pressure.

   

   Figure 9: Universal Torque Specifications

   This table provides universal torque specifications in FT/LBS and recommended safety thread turns for various stud sizes, including 9/16 inch relevant to these spacers.

7. Reinstall the Wheel:

   Place the wheel back onto the newly installed wheel spacer, aligning the wheel's bolt holes with the spacer's studs. Hand-tighten your vehicle's original lug nuts onto the spacer's studs.

8. Final Torque of Wheel Lug Nuts:

   Lower the vehicle slightly so the tire makes contact with the ground but the full weight is not on it. Using a torque wrench, tighten the wheel lug nuts to your vehicle manufacturer's specifications. Tighten in a star pattern. Fully lower the vehicle and remove the jack and jack stands.

9. Check Clearance:

   Ensure there is adequate clearance between the tire and fender, and any other suspension components. A minimum of 12mm (1/2 inch) clearance is recommended to prevent rubbing.

   This image visually demonstrates the increased wheel clearance and wider stance achieved after installing wheel spacers.

Operating Benefits

Installing ECCPP wheel spacers offers several operational benefits:

• Aggressive Stance: Moves wheels further out from the hub for a more assertive vehicle appearance.
• Improved Handling: Widens the vehicle's wheel base, increasing the extra gap between the tire and vehicle hub assembly, which can lead to better handling characteristics.
• Increased Stability: Lowers the center of gravity, benefiting stability at high speeds and increasing resistance to side roll-over.
• Enhanced Flexibility: Improves flexibility when turning.
• Tire Clearance: Increases tire clearance, fixes brake caliper clearance issues, and allows for the installation of lift/lowering kits and wider, larger, or high-traction tires.

Figure 11: Widened Wheel Base

This image illustrates how wheel spacers widen the vehicle's wheel base, increasing the distance between the tires and the hub assembly.

Figure 12: Lowering the Center of Gravity

This image depicts how wheel spacers contribute to lowering the vehicle's center of gravity, which can improve high-speed stability.

Figure 13: Increased Stability and Flexibility

This image shows how wheel spacers can increase vehicle stability and resistance to roll-over, while also improving turning flexibility.

Maintenance

Regular maintenance is crucial for the longevity and safety of your wheel spacers.

• Re-torque: Re-torque all lug nuts (both spacer-to-hub and wheel-to-spacer) after the first 50-100 miles of driving. This is critical as components settle.
• Periodic Checks: Re-check torque every 2000-3000 miles or during routine tire rotations.
• Inspection: Periodically inspect the spacers for any signs of wear, damage, or corrosion. Ensure all bolts are secure and there is no visible movement.
• Cleaning: Keep the spacers and hub surfaces clean to prevent rust buildup, which can affect fitment.
