Pillow Ball Mount

The TEIN Rear Pillow Ball Upper Mount (part number PRT61-31S10) is a high-performance suspension upgrade designed to enhance vehicle handling and responsiveness. This component replaces the factory upper mount, integrating pillow ball bearings to create a more direct connection between the chassis and the suspension components. This direct linkage minimizes flex and play, leading to sharper steering input and a more connected feel to the road. The use of durable pillow ball bearings ensures longevity and consistent performance under demanding driving conditions. Its design aims to reduce unwanted movement in the suspension geometry, which can be particularly beneficial during spirited driving or track use.

Some sources suggest this part may be discontinued or that related parts (like PRT60-31S10) exist, highlighting the importance of confirming compatibility before purchase. The MVP Motorsports site shows no direct vehicle search results for this part number, further emphasizing the need for manual verification.
