It drops in as a direct-fit replacement for the 2015-2020 Cadillac Escalade, 2015-2018 Chevrolet Silverado 1500, 2015-2020 Chevrolet Suburban, 2015-2020 Chevrolet Tahoe, 2015-2018 GMC Sierra, 2015-2018 GMC Sierra 1500, 2015-2020 GMC Yukon and 2015-2020 GMC Yukon XL — see the Buyer's Guide tab for engine details and the full list.

  • Upgraded design: features a patent-pending top seal block assembly engineered to relieve and restore cyclic fluid pressure on demand, addressing the top-seal fluid leaks that commonly cause strut failure on these applications.
  • Increased reliability: built with stronger, more durable mounting points to help support long service life under tough conditions.
  • Safer installation: arrives as a pre-assembled loaded strut and spring, eliminating the need for a spring compressor during installation.
  • Advanced technology: retains the same magnetorheological (MR) dampening functionality as the factory unit to restore like-new ride feel.

Frequently Asked Questions

What does this strut assembly do?

It is a front loaded strut-and-coil-spring assembly that dampens suspension movement and supports ride height, while retaining the magnetorheological (MR) dampening functionality of the factory magnetic ride control unit.

Does it fit my vehicle?

It is a direct-fit replacement for select 2015-2020 Cadillac Escalade, Chevrolet Suburban/Tahoe, GMC Yukon/Yukon XL and 2015-2018 Silverado 1500 and Sierra/Sierra 1500 models with magnetic ride control. Check the Buyer's Guide tab.

Do I need a spring compressor to install it?

No. It ships as a pre-assembled loaded strut and spring, which eliminates the need to use a spring compressor during installation.

What is the upgraded top seal design?

It uses a patent-pending top seal block assembly designed to relieve and restore cyclic fluid pressure on demand, addressing the top-seal fluid leaks that commonly lead to strut failure on these applications.

Should I replace both sides at once?

This listing is for one assembly. Replacing struts in matched pairs across the same axle is recommended for balanced, even suspension performance; confirm your needs with the vehicle service information.
