Detroit Speed Engineering 030346DS Lowered Hubpack Uprights Fox Body Strut

Detroit Speed Engineering's 030346DS Lowering Hubpack Uprights are a bolt-in performance suspension upgrade engineered specifically for 1979–1993 Fox Body Mustang strut-based front suspension. Built from forged aluminum with a factory-integrated 2-inch drop, these uprights modernize the Fox Body platform with improved stance, sharper steering response, and expanded brake system compatibility.

Key Features:

• Forged Aluminum Construction: Lightweight yet rigid design reduces suspension deflection for more precise handling and sharper steering feedback
• Built-In 2-Inch Drop: Integrated lowering improves stance and optimizes weight distribution for better cornering performance on street, autocross, and track applications
• Hubpack Bearing System: Eliminates spindle pin flex found in the factory design, reducing maintenance requirements and improving long-term durability
• S550 Mustang Brake Compatibility: Designed to accept 2015–2024 Ford Mustang OE and aftermarket brake systems, opening up a wide range of modern, high-performance braking upgrades
• Optimized Ackermann & Bump Steer Geometry: Reduces unwanted toe changes under compression for more predictable, confident turn-in and high-speed stability
• Bolt-On Installation: Includes all necessary mounting hardware for a straightforward installation without custom fabrication
• Made in the USA: Designed and manufactured in Mooresville, North Carolina

The 030346DS Lowering Hubpack Uprights are compatible with strut-based Fox Body front suspension setups and are also sold as a standalone component for builders running aftermarket coilovers or QA1 struts. These uprights are a key component in Detroit Speed's broader Fox Body suspension ecosystem and are directly compatible with the DSE Front Suspension Speed Kit lineup.
