Dorman 949-650XD Front Loaded Magnetic Strut Assembly with OE FIX Technology

The Dorman 949-650XD is a complete front loaded strut assembly engineered specifically for Cadillac, Chevrolet, and GMC vehicles equipped with magnetic ride control (MagneRide) suspension systems. This OE FIX assembly addresses a common failure point in factory struts by incorporating an upgraded patent-pending top seal design that prevents the fluid leaks and seal deterioration that plague original equipment assemblies.

OE FIX Enhanced Design:

Factory magnetic strut assemblies typically fail due to fluid leaks in the top seal assembly caused by continuous friction, heat, and fluid pressure during compression and rebound cycles. This upgraded assembly features an innovative top seal block that more effectively relieves and restores cyclic fluid pressure on demand, virtually eliminating the internal pressurization that leads to premature seal failure and loss of damping performance.

Key Features:

• Complete pre-assembled strut and coil spring assembly ready to install
• Magnetorheological (MR) dampening technology restores factory ride quality
• Adjustable damping with gas-charged design for optimal performance
• 50mm outer housing diameter with 128mm compressed length
• Bolt-on upper mount and T-bar lower mount configuration
• Includes protective boot and spring seat
• Eliminates need for dangerous spring compressor tools during installation
• Limited lifetime warranty coverage

This complete assembly saves installation time by arriving fully assembled and tested, reducing labor by up to one hour per side while eliminating the safety risks associated with compressing high-tension coil springs. The advanced magnetic ride control functionality matches original equipment specifications to deliver responsive handling and comfortable ride characteristics.
