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 the Nissan 300ZX (Z32) from 1990 to 1996. These high-performance bushings are engineered to provide a more direct and solid connection between the differential and the chassis, helping to improve overall handling and power transfer. Crafted for enthusiasts seeking enhanced stability and reduced wheel hop, these bushings are ideal for track days, spirited driving, or anyone looking to upgrade their vehicle’s drivetrain response. Made from durable CNC-machined 6061-T6 billet aluminum, they offer superior strength and longevity compared to stock components, ensuring consistent performance under demanding conditions.

Key Features

Designed to eliminate the stock mushy rubber bushings, these solid aluminum bushings help to reduce differential movement and wheel hop, resulting in more precise power delivery. The precision CNC machining ensures a perfect fit and smooth surface finish for optimal performance. Constructed from lightweight yet robust 6061-T6 aluminum, these bushings resist deformation and corrosion, maintaining their integrity over time. Their straightforward installation process allows for a secure, bolt-on upgrade that enhances the vehicle’s handling characteristics without compromising daily drivability. The solid design also contributes to a more responsive feel during aggressive driving, making them a popular choice among performance-oriented Nissan owners.

Construction & Design

These bushings are machined from high-grade 6061-T6 aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. The precision CNC process ensures tight tolerances and a seamless surface finish, which helps to prevent unwanted movement and noise. The solid aluminum construction replaces the stock rubber components, providing a more direct and durable connection that supports aggressive driving and increased power output.

Driving Feel & Feedback

By replacing the stock bushings with these solid aluminum versions, drivers will notice a more immediate and responsive feel from the differential. The reduction in differential movement translates to improved handling, especially during high-speed cornering and acceleration. The upgrade helps to minimize wheel hop and drivetrain slack, offering a more confident and controlled driving experience.

Installation & Fitment

Installation involves removing the existing rubber bushings and replacing them with these CNC-machined aluminum units. The process is straightforward for those with basic mechanical skills, but verifying fitment against your specific vehicle model and part number is recommended to ensure compatibility.

What’s Included

The package includes a set of solid aluminum differential bushings designed specifically for the Nissan 300ZX (Z32) from 1990-1996, along with all necessary hardware for a secure installation.
