PRT 921390 Complete Strut and Coil Spring Assembly

The PRT 921390 is a complete suspension strut and coil spring assembly engineered as a direct OE replacement. Produced by Performance Ride Technology (PRT), a global brand backed by over 30 years of ride control and suspension manufacturing experience, this pre-assembled unit is designed to restore your vehicle's original ride quality, handling, and safety straight out of the box.

Key Features:

• Pre-assembled complete unit — integrates the strut, coil spring, dust cover, and spring seat for fast, straightforward installation
• Micro-smooth chrome-plated piston rod — ensures consistent wear surface and corrosion resistance for long-term durability
• High-quality carbon steel coil spring — heat-treated, stress-relieved, and salt-spray tested; designed to match factory ride height and performance
• Urethane bump stop — absorbs road impacts and helps protect surrounding steering and suspension components
• Dual-tube internal construction — with vehicle-specific valving and high-performance all-weather hydraulic oil
• OE-quality top mount and bearing — engineered for low steering torque and tested under extreme load conditions
• Corrosion-resistant outer tube — provides long-lasting protection against rust and wear
• Meets or exceeds original equipment (OE) performance standards

The PRT 921390 strut and coil spring assembly eliminates the need for a spring compressor or special tools, saving significant time compared to traditional component-by-component strut replacement. It is available for popular domestic and import passenger car, SUV, and light truck applications.
