Prothane 6-1712 Front Coil Spring Spacer Lift Kit - 2.5 Inch

The Prothane 6-1712 is a front coil spring spacer lift kit delivering 2.5 inches of front lift for 2005–2009 Ford F-250 Super Duty 4WD trucks. This kit provides a cost-effective alternative to full suspension lift systems, allowing you to raise your truck's front end while retaining your factory coil springs.

Prothane manufactures these spacers from high-performance polyurethane — a significant upgrade over the soft rubber isolators found on stock suspension. Polyurethane resists deformation under variable load pressure, delivering greater durability and long-term reliability compared to OEM rubber components. The increased material firmness provides a more responsive feel under the front end while maintaining safe, dependable ride characteristics.

Available in red or black — both colors share the same durometer (hardness rating) and performance characteristics. The black variant includes a small amount of graphite blended into the polyurethane, which can help reduce squeaking. Regardless of color, applying the included pre-lube during installation is recommended to prevent noise.

Key Features:

• Delivers 2.5 inches of front lift over stock ride height
• Installs over existing factory coil springs — no spring replacement needed
• High-performance polyurethane construction — more durable than OEM rubber
• Available in red or black finish
• Kit includes two coil spring spacers and complete installation instructions
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

The Prothane 6-1712 is an excellent solution for F-250 Super Duty owners looking to gain meaningful front lift height without the expense or complexity of a full suspension lift kit.
