Dorman - OE Solutions Suspension Strut and Coil Spring Assembly P/N:949-730XD

$814.99

Description

Replace a worn or leaking factory magnetic strut on your Chevrolet, GMC or Cadillac SUV or truck with the Dorman OE Solutions Loaded Magnetic Strut Assembly 949-730XD. This complete strut and coil spring assembly arrives pre-assembled as a direct-fit front replacement for many vehicles, among them the 2015-2018 Chevrolet Silverado 1500, 2015-2018 GMC Sierra 1500 and 2015-2020 Chevrolet Tahoe. See the Buyer's Guide tab for the full list.

On these magnetic-ride-control applications, original front strut and spring assemblies commonly fail when the top seal deteriorates from the friction, heat and fluid pressure of each compression and rebound cycle, leading to leaks and lost damping. If a leaking top seal is the cause, this Dorman OE FIX unit replaces it with an upgraded design.

Upgraded top seal: a patent-pending top seal block assembly relieves and restores cyclic fluid pressure on demand, addressing the internal pressurization inherent in the original design.
Increased reliability: engineered with stronger, more durable mounting points designed to help provide long service life under tough conditions.
Safer installation: pre-assembled strut and spring eliminates the need for a spring compressor.
Magnetic ride control: features the same magnetorheological (MR) dampening as factory equipment.

Frequently Asked Questions

What is a loaded magnetic strut assembly?

It's a pre-assembled front strut and coil spring unit with magnetorheological (MR) dampening. Because it arrives fully assembled, installation does not require a spring compressor.

Which vehicles does the Dorman 949-730XD fit?

It fits many vehicles, among them the 2015-2018 Chevrolet Silverado 1500, 2015-2018 GMC Sierra 1500 and 2015-2020 Chevrolet Tahoe. See the Buyer's Guide tab for the full list.

Does it keep the magnetic ride control feature?

Yes. It features the same magnetic ride control functionality, or magnetorheological (MR) dampening, as the factory equipment on these applications.

How is the top seal different from the original?

It uses a patent-pending top seal block assembly that relieves and restores cyclic fluid pressure on demand, addressing the internal fluid pressurization inherent in the original equipment design.

What are signs this strut may need replacing?

Fluid leaks around the top seal, reduced damping, a rougher ride, or a failed inspection can indicate strut wear. Diagnose the cause before replacing, as other suspension parts can produce similar symptoms.
