KYB SM5285 Suspension Strut Mount Kit - Front

KYB SM5285 Strut Mount Kit Overview

KYB SM5285 is a front suspension strut mount kit built for OE-style replacement on select Chevrolet, Pontiac, and Cadillac applications. It addresses the vibration, noise, and harshness that worn upper mounts can transmit into the cabin while helping restore steering feel and front-end alignment.

Compatible With 2011-2017 Chevrolet Caprice, front; 2008-2009 Pontiac G8, front; 2004-2006 Pontiac GTO, front; and 1997-2001 Cadillac Catera, front. This KYB Mount Components part is engineered for direct-fit service on the front suspension.

Key Features

• OE-quality replacement strut mount components for application-specific fitment
• Superior rubber construction helps reduce noise, vibration, and harshness
• Mount bearings support smoother steering response and front-end alignment retention
• Front bearing plate design serves as a steering pivot and supports vehicle weight
• Matched-grade studs and nuts for consistent assembly quality

Detailed Product Description

KYB SM5285 is part of KYB’s Mount Components line, a product range focused on replacing worn suspension insulators and bearing plates with components matched to the vehicle application. On vehicles such as the Chevrolet Caprice, Pontiac G8, Pontiac GTO, and Cadillac Catera, the front strut mount plays a critical role in isolating road impact while allowing the suspension and steering system to move smoothly. When the original mount hardens or wears, the result is often increased cabin noise, vibration, and a less precise steering feel. This KYB strut mount kit is built to address those conditions with OE-style replacement construction.

This part cross-references Monroe Shocks & Struts (e.g., 903932) for the same application.

What It Helps Address

• Clunking or knocking from the front suspension
• Excess vibration transferred into the cabin
• Harsh ride feel caused by worn upper mount insulators
• Loose or imprecise steering response
• Front-end alignment issues related to worn mount bearings

Installation Notes and Tips

Install SM5285 on the front suspension only, following the vehicle-specific service procedure for the Chevrolet Caprice, Pontiac G8, Pontiac GTO, or Cadillac Catera. Inspect the strut assembly, bearing plate, and surrounding suspension components before installation, and replace any worn parts that could affect steering or alignment. After installation, a professional wheel alignment is recommended to verify front-end geometry.

Quality Assurance

KYB positions its Mount Components line as OE-quality replacement hardware for suspension service, with application-specific design and bearing support intended to maintain steering performance and ride control. SM5285 is built to the standards associated with KYB strut mount and bearing plate replacements.
