Powerflex BMW Drivetrain Parts

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

The Powerflex Rear Diff Bushing for BMW Z3, E30 3 Series, and 318Ti is a high-performance replacement for the factory rubber bushings in the rear differential. This upgrade is ideal for improving handling, power delivery, and drivetrain stability, especially on aging vehicles where the original bushings may have deteriorated.

Key Features:

  1. Polyurethane Construction: Unlike the OEM rubber bushings, Powerflex bushings are made from durable polyurethane, which resists wear from exposure to heat, oil, and road debris. This increases the longevity of the bushing and ensures consistent performance over time.

  2. Handling Improvements: The stiffer polyurethane material significantly reduces the flex and movement of the differential during acceleration, braking, and cornering. This helps improve the overall stability and precision of the vehicle’s rear-end, enhancing cornering performance and delivering better power transfer to the wheels.

  3. Versions for Different Needs:

    • Road Series: Designed for daily driving, these bushings offer an excellent balance of performance and comfort, maintaining near-factory levels of ride quality while improving rear differential control.
    • Black Series: These bushings are made from a much stiffer polyurethane (95A durometer) and are designed for motorsport or track applications. They provide maximum control and minimal flex, at the expense of an increase in NVH (noise, vibration, and harshness).
  4. Direct Fitment: These bushings are designed as direct replacements for the stock bushings, making installation relatively straightforward. This is especially useful for older models like the E30 and Z3, where original bushings may have degraded or cracked, causing clunking noises and excessive differential movement.

  5. Performance Gains: With reduced differential movement, drivers can expect sharper throttle response, improved traction under load, and better cornering dynamics, making it a perfect upgrade for those who want to refresh and enhance the performance of their BMW's rear suspension.

Application:

  • BMW Z3
  • BMW E30 3 Series
  • BMW E36 318Ti (Compact)

This Powerflex rear diff bushing upgrade is ideal for anyone looking to improve the handling characteristics of their BMW while adding durability and reliability to the drivetrain setup.

The Powerflex Rear Diff Rear Bushings for the BMW E60 5-Series and E63 6-Series are performance-oriented components designed to upgrade the rear differential mount system. Here’s a detailed description of their features and benefits: Durable Polyurethane Construction: These bushings are crafted from high-quality polyurethane, which is known for its resilience and ability to withstand harsh conditions. Unlike factory rubber bushings that can degrade over time, Powerflex bushings maintain their integrity and performance even under extreme driving conditions. Enhanced Differential Control: The stiffer nature of the polyurethane material reduces unwanted movement of the rear differential during acceleration and cornering. This results in improved control and stability, allowing for better power delivery and overall performance. Improved Handling Dynamics: By minimizing differential movement, the Powerflex bushings help maintain the proper alignment of the rear suspension. This leads to enhanced handling characteristics, providing a more connected and responsive driving experience, especially in spirited or performance driving scenarios. Minimized Wear and Tear: The durable construction of these bushings reduces the likelihood of premature wear, extending the lifespan of the differential and surrounding components. This makes them a smart investment for both daily drivers and performance enthusiasts. Reduced NVH Levels: While offering performance enhancements, Powerflex has designed these bushings to keep noise, vibration, and harshness (NVH) increases to a minimum. This balance allows for a comfortable driving experience without sacrificing the benefits of improved handling. Easy Installation: Specifically designed for the BMW E60 and E63 models, these bushings offer a direct replacement for the factory components. This ensures a hassle-free installation process, making them accessible to both DIY enthusiasts and professional mechanics. Ideal for Performance Upgrades: Whether you're modifying your vehicle for track use or simply looking to enhance everyday performance, these bushings provide a significant upgrade over the stock components, making them a popular choice among BMW enthusiasts.
