What's Included:

• Pre-assembled premium strut
• OE-style upper bearing plate

Key Features:

• Pre-assembled unit — eliminates the need to compress or transfer the factory coil spring, saving significant installation time with no special tools required
• Direct bolt-in fitment — no drilling, cutting, or welding required
• Nitrogen-charged twin-tube design — reduces aeration for improved damping performance and extended service life
• Micro-smooth chrome-plated piston rod — resists corrosion and pitting for long-lasting durability
• Corrosion-resistant outer strut tube — protects against rust and road debris
