2024-2026 Ford Mustang S650 Chassis Mounted Rear Diffuser

Pre-Order:

It's FINALLY here! Our best product to-date, hands down. After a long period of testing, R&D, design/manufacturing tweaks, and more... Our Chassis-Mounted S650 Ford Mustang Rear Diffuser is now available for pre-order, giving early buyers priority access to our first production run. Early units are scheduled to begin shipping in January 2026, although some orders may ship sooner as initial batches are completed.

Each Diffuser itself is fully manufactured in-house at LVA. The only items produced off site are the powdercoated metal chassis mounting brackets, which are built by one of our trusted heavy metal manufacturing partners. Pre orders allow us to secure a dedicated bulk run of these brackets and streamline production for the earliest customers.

All pre-order units are fulfilled in the order they are received. Reserving yours now guarantees your spot in the first wave of shipments!

Description:

• True chassis mounted rear diffuser designed specifically for the S650 Mustang platform
• Secures to the chassis using four proprietary metal brackets included with your purchase
• Built from LVA’s patented Hybrid Aluminum and CNC machined in house at our Indiana facility for an OEM plus level fit and finish
• Extends three feet under the rear bumper tying into the rear differential mount to stop airflow from getting trapped between the spare tire well and bumper cover
• Reduces drag and increases rear end stability by maintaining a clean airflow path
• Optimized three degree angle of attack for efficient aerodynamic performance
• Fully customizable with optional edge trim colors, beauty washer colors, LVA logo colors, and more
• Compatible with optional Rear Spats that mount to the lower corners of the rear bumper to complete the look and flow with our LVA Splitters and Side Skirts
• Designed with tight tolerances for a smooth, precise installation
• No rear bumper removal required, reuses factory mounting locations, and arrives pre-drilled with a complete hardware kit
