Show original supplier description
The TEIN Rear Pillow Ball Upper Mount, part number PRM33-31S10, is a high-performance suspension upgrade designed to improve vehicle handling and responsiveness. This component falls under the Pillow Ball Spherical Upper Shock / Strut Mount category, utilizing a pillow ball design for precise movement and reduced deflection. This rear upper mount is engineered by TEIN, a recognized name in performance suspension. It is sold as a pair and is intended to replace the factory upper mount, offering a more direct connection between the chassis and the shock absorber. The use of pillow ball bearings in place of traditional rubber bushings minimizes unwanted flex, leading to a sharper steering feel and improved suspension feedback. While specific vehicle fitment for the PRM33-31S10 is not exhaustively detailed across all provided sources, it is listed as a component for the 2003-07 Honda Accord CM. There is also a mention of a "SORRY, NO MATCH" result for an INFINITI G37 search, indicating it may not be compatible with all vehicle models. Further verification of application is recommended through the manufacturer's fitment guide or a specialized dealer. As a performance-oriented part, this upper mount may alter the vehicle's ride characteristics, potentially resulting in a firmer feel compared to stock components. Users should consult with a professional if they have concerns regarding installation or compatibility with their specific suspension setup.
