This shock absorber is designed to match the fit and function of the original part on specified vehicles, and is engineered for durability and reliable performance.

Product Features:

• Direct replacement – this magnetic ride shock absorber features the same advanced technology as the original equipment on specific vehicles.
• Restores performance – magnetic shocks react far faster than conventional shocks – as fast as 1/1,000th of a second.
• Smart solution – offers like-new ride quality, handling and safety for far less than dealership replacement
• Maintains value – replacing worn magnetic shocks preserves the resale value for vehicles originally equipped with this expensive option

When an original equipment front strut fails on certain GMC, Chevrolet and Cadillac SUVs and trucks equipped with magnetic ride control, it’s often due to fluid leaks that develop in the strut’s top seal assembly. Over time and miles, the factory seals deteriorate from the friction, heat and fluid pressure generated during every compression and rebound cycle of the strut. Ultimately that continuous cyclic load leads to seal failure and with it a loss of damping effectiveness and overall suspension performance, and potentially a failed state inspection. This Dorman OE FIX magnetic strut features an innovative upgraded top seal design that prevents this common and costly cause of strut failure. Our patent-pending top seal block assembly absorbs impact pressure better by more effectively and efficiently relieving and restoring cyclic fluid pressure on demand, virtually eliminating the relentless and damaging internal fluid pressurization inherent in the original equipment’s design. In addition, this strut features more durable mounting points to help ensure long service life under the toughest conditions.

Product Features:

• Upgraded design – this loaded magnetic front strut features an innovative top seal design to prevent fluid leaks that can cause strut failure on certain GMC, Chevrolet and Cadillac SUVs and trucks
• Increased reliability – engineered with stronger and more durable mounting points to help ensure long service life under the toughest conditions
• Advanced technology – features the same magnetic ride control functionality, or magnetorheological (MR) dampening, as factory equipment to restore like-new ride feel and performance
• Direct replacement – designed and manufactured to exacting specifications to match the performance of the original equipment strut in specified applications
