SPL Parts PRO Solid Differential Bushings

Part #: SPL SDB S14

Overview

The SPL Parts PRO Solid Aluminum Differential Mounting Bushings (SDB) are designed to replace the stock rubber bushings on the differential pumpkin of select Nissan models. These precision CNC-machined bushings are crafted from high-quality 6061-T6 Billet Aluminum, offering a durable and reliable upgrade for enthusiasts seeking improved drivetrain stability. Ideal for performance-oriented drivers and car builders, these bushings help eliminate the mushy feel of stock mounts, providing a more direct connection between the differential and the chassis. This results in enhanced power transfer, reduced wheel hop, and improved overall handling during aggressive driving or track use. Designed specifically for the 1995-1998 Nissan 240SX (S14) and adaptable to other models like the Skyline R34, Z32, S13, and S15, these bushings are an excellent choice for those looking to optimize their vehicle’s rear drivetrain response. Whether you’re building a street performance car or preparing for track days, these solid bushings support a more responsive and predictable driving experience by minimizing differential movement and drivetrain flex.
