Overview

The Stillen rear diffuser is a replacement panel designed to replace the factory fiberglass fins on your 2005-2006 Ford GT. It is developed and manufactured in-house and includes a Limited Lifetime Warranty.

Show original supplier description

This panel is meticulously crafted from robust polyurethane, ensuring longevity and resistance to damage from minor impacts. It features a painted matte black finish for an aggressive look, with the added benefit of being paintable to perfectly match your vehicle's color scheme. This diffuser is developed and manufactured in-house by Stillen and comes backed by a Limited Lifetime Warranty. This replacement diffuser does not include the factory underbelly panel; ensure yours is in good condition before installation. The installation process requires drilling out the factory rivets and securing the new diffuser with the supplied hardware. The product is designed for rear mounting and is installed using 3M Automotive Tape. It is compatible with the 2005 and 2006 Ford GT Base RWD models.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
