Replacement Spoiler Blades 5in x 60in 90 Deg

The Replacement Spoiler Blades 5in x 60in 90 Deg from FIVESTAR are precision-engineered aerodynamic components designed for drivers and fabricators who demand factory-spec performance without the factory price tag. These blades replace damaged, worn, or outdated spoiler sections on vehicles where stock rear wing assemblies require restoration or upgrade. Whether you're rebuilding a race car, restoring a classic with modern aerodynamic intent, or repairing collision damage, replacement spoiler blades are the cost-effective solution to achieving proper downforce and visual aggression without full-chassis modifications.

At 5 inches tall and 60 inches wide with a 90-degree blade angle, these replacement blades deliver consistent air pressure management across the rear axle for improved stability at highway and track speeds. The 90-degree geometry maximizes contact surface area while reducing turbulent wake behind the vehicle—a critical factor for vehicles in the 3,000–4,500 lb weight range. FIVESTAR's manufacturing tolerances ensure blade-to-mounting-bracket alignment that minimizes vibration and flutter at sustained speeds above 60 mph. The lightweight construction (2.35 lbs per blade) means reduced unsprung mass that won't compromise handling or fuel economy, while the compact 30.1-inch packaged length simplifies shipping and on-site storage for shops and individual builders alike.

Mechanics and performance enthusiasts will find these blades compatible with FIVESTAR spoiler mounting systems and universal two-point or three-point wing brackets commonly fitted to American muscle cars, late-model sedans, and track-build platforms. Installation requires no welding when paired with factory or aftermarket extrusion mounts; fastener hardware and alignment pins ensure repeatable bolt-on fitment. For shops performing frequent spoiler repairs or custom aero fabrication, stocking these replacement blades eliminates lead times and reduces labor hours on bracket fabrication. Proper installation with torque-spec fasteners and thread-locking compound will deliver years of reliable aerodynamic performance.
