BMW Differential and Gearing Upgrades

Upgrading various parts of the differential can have tremendous benefits in your car's performance. It's easy to forget that the differential is a source for making your car faster and handle better so it's often overlooked. The engine is not the only place to make the car faster. Our differential options vary from gearing upgrades to limited slip conversions. You can purchase the ring & pinion gear sets on their own (professional installation required) or have us build a diff around your own specifcations. The options are almost endless! Every custom-built diff is fully rebuilt with seals and bearings. We also design and supply bushing options to reduce driveline wind-up, finned differential covers for better cooling, and more!

Ratio Changes - Changing the differential gearing is one of the best and most-effective upgrades you can make on any BMW (old or new). By using a shorter (numerically higher) final drive ratio you are increasing your RPM relative to road speed - this puts you in a more powerful RPM range than before! Since you're in a 'meatier' part of the power band you're now putting down more power/torque to the ground. If you can trade outright top speed for faster acceleration at daily speeds then this is the perfect upgrade for you.

Limited Slip Upgrades - Sadly, many BMWs today are not equipped with a limited slip (posi-traction) differential. BMW has tried to compensate by using traction control that cuts power at the engine or applies the brakes to retard wheel spin (or a combination of both). But nothing beats the function and feel of a a true LSD which may be why BMW continues to use them in M cars. Our LSD upgrades can be done a number of different ways - a factory-type limited slip unit with either 2 or 3 clutch packs, helical type, OS Giken unit, or something truly custom. We can also vary ramp angles and setup to change the limited-slip behavior under acceleration, deceleration, and cornering. Need a custom diff? Call or e-mail to have a quote.

Differentials serve the key purpose of transmitting power from the driveshaft to the axles. Factory rubber bushings absorb some of this power to allow for cushy, comfortable acceleration, at the expense of performance. Many OEM differential bushings are fast-wearing and failure prone, resulting in driveline slop and thunks when shifting or going over bumps. Powerflex polyurethane differential bushings are firmer than OEM rubber bushings, eliminating associated driveline slop and allowing for the crisp application of power to the ground, resulting in better throttle response and control. Powerflex is the number one selling suspension bushing manufacturer in Europe. Their experience with polyurethane bushing material and state-of-the art manufacturing techniques allows them to produce premium performance bushings, made to exact-fit standards. Powerflex performance polyurethane bushings are built to last longer than OEM rubber bushings, while improving performance and allowing for a more engaging driving experience. Use of Powerflex Copper Grease PCG1 is recommended for ease of installation. Periodic reapplication is recommended to extend squeak-free service life of bushings. Powerflex Black Series bushings are the ultimate in track and race bushings. Need bushings for a car that's street-driven? Powerflex street bushings are an ideal alternative for street driven vehicles and those that see occasional autocross or track time. Powerflex is proud to offer a lifetime warranty to the original purchaser on all products.

The Powerflex Black Series Rear Diff Rear Mount Bushing for the BMW E36 3 Series (1990-1998) is engineered to deliver extreme durability and precise handling for motorsport and performance-focused applications. As part of the Black Series lineup, this bushing is designed to offer maximum stiffness for track and competition use. Here’s a detailed look at its features: High-Rigidity Polyurethane Composition: The Black Series bushings use a specialized polyurethane formula that offers significantly more stiffness than standard bushings. This provides greater control over the rear differential, minimizing flex and unwanted movement, which is essential during high-performance and track driving conditions. Improved Power Delivery and Traction: By locking the differential securely in place, this bushing allows more direct power transfer to the rear wheels. This eliminates any excess movement in the differential housing, leading to faster response times during acceleration and improved traction when pushing the car hard, particularly during cornering or launches. Superior Rear-End Stability: The Powerflex Black Series bushing significantly enhances the stability of the rear differential, reducing play and keeping the rear suspension geometry in check. This helps improve rear-end control during aggressive cornering, making the car feel more composed and predictable when driving at the limit. Designed for Motorsport and Extreme Use: Built for racing and motorsport environments, this bushing is extremely resistant to wear and tear. It can handle the high stresses associated with track driving, including heat, road debris, and extreme loads. The increased durability ensures that the bushing performs consistently, even under the most demanding conditions. Sharper Handling Response: The rigidity of the Black Series bushing helps to reduce any slack in the rear differential mounts, allowing for quicker responses to steering inputs. The result is tighter, more precise handling, which is crucial for maintaining control and balance during high-speed cornering or rapid directional changes. Maximized Suspension Efficiency: With minimal differential movement, the rear suspension remains in its optimal position, allowing the system to work more effectively. This maximizes grip and reduces tire wear, ensuring that the car remains stable and predictable through both straight-line acceleration and aggressive cornering. Increased NVH for Performance Focused Setups: Due to the increased stiffness of the bushing, there will be an inevitable rise in noise, vibration, and harshness (NVH) levels compared to rubber or softer polyurethane options. This is a necessary trade-off for the improved control and performance, making the bushing more suitable for cars that see regular track use or are dedicated to motorsport. Direct Fit for BMW E36 (1990-1998): The Powerflex Black Series bushing is a direct replacement for the rear differential rear mount on the BMW E36 3 Series. It fits perfectly without the need for modifications, making it an effective upgrade for serious enthusiasts looking to enhance the performance of their vehicle’s drivetrain. In conclusion, the Powerflex Black Series Rear Diff Rear Mount Bushing for the BMW E36 3 Series is a high-performance solution aimed at track-oriented drivers or those looking to significantly stiffen the rear differential mounting points. It offers improved handling precision, enhanced power delivery, and exceptional durability, but comes with increased NVH levels, making it best suited for performance-focused builds or race cars.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.  *Door Buster Special - New Product*

    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

    Differentials serve the key purpose of transmitting power from the driveshaft to the axles. Factory rubber bushings absorb some of this power to allow for cushy, comfortable acceleration, at the expense of performance. Many OEM differential bushings are fast-wearing and failure-prone, resulting in driveline slop and thunks when shifting or going over bumps. Your BMW G80/G82/G87 will improve in: Improved Handling and Stability - Upgrading to an aftermarket rear differential front mount bushing can do wonders for your car's handling and stability. These bushings are designed with performance in mind, reducing unwanted movement of the differential. Reduced Wheel Hop - Wheel hop can be a drag, both figuratively and literally. An upgraded front mount bushing helps minimize wheel hop, especially during hard acceleration or aggressive driving. Say goodbye to that unsettling bounce and hello to smoother power delivery.

    Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

    By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

    Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

    Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.
