When an original equipment front strut assembly fails on certain Cadillac SUVs 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 ride control shock absorber features an innovative upgraded top seal design that prevents this common and costly cause of 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 assembly features more durable mounting points to help ensure long service life under the toughest conditions.

Product Features:

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