BMW Suspension Bushings & Mounts

BMW’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience.  Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. 

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting.  The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

We offer these thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

The BMW E46 / E36 / Z4 / X3 Rear Trailing Arm Front Bushing by Powerflex is a precision-engineered suspension upgrade designed to improve the handling and durability of several popular BMW models. This bushing replaces the factory rubber bushing located at the front of the rear trailing arm with a high-performance polyurethane version.

Product Features:

1. Polyurethane Construction: Unlike standard rubber bushings, Powerflex bushings are made from durable polyurethane, a material known for its superior resistance to wear, heat, and degradation from oils and contaminants. This leads to a longer lifespan and more consistent performance over time.

2. Stiffness for Enhanced Control: The polyurethane bushings provide increased stiffness, reducing unwanted flex and movement in the rear trailing arms. This helps to maintain better control of the rear wheel alignment, resulting in more stable and predictable handling, especially during cornering, acceleration, and braking.

3. Reduced Deflection: By reducing the deflection of the rear trailing arms, these bushings help to improve traction and rear suspension geometry. This makes the car feel more planted and responsive, reducing wheel hop and improving grip under load.

4. Direct Replacement: The Powerflex bushings are designed as a direct replacement for the factory-installed rubber bushings, meaning they will fit perfectly into the existing suspension setup without requiring modifications. This makes installation straightforward while significantly enhancing the suspension’s performance.

5. Longevity & Resistance: Polyurethane bushings are highly resistant to common automotive contaminants such as road debris, oil, water, and heat. This makes them a more reliable choice for drivers looking for a long-term solution to suspension wear and tear.

Compatible Models:

• BMW E46 (3 Series, 1999-2006)
• BMW E36 (3 Series, 1991-1999)
• BMW Z4 (E85/E86, 2003-2008)
• BMW X3 (E83, 2003-2010)

Advantages:

• Improved Rear-End Stability: Provides more precise alignment and control of the rear suspension, resulting in sharper handling.
• Durable & Long-Lasting: Outperforms rubber bushings in terms of longevity and wear resistance.
• Enhanced Ride Quality: Reduces unwanted suspension movement, improving driving dynamics and cornering performance.
• Easy Fitment: A direct replacement for stock bushings, with no special modifications required.

For drivers seeking a more connected and performance-focused feel from their BMW, the Powerflex Rear Trailing Arm Front Bushing is a significant upgrade over stock rubber bushings, delivering improved handling, reduced wear, and enhanced driving enjoyment.

For all 2001 to 2005 325xi and 330xi. For convenience, we have assembled this bushing carrier bracket kit, to save you time when changing our control arm bushings. It includes two bushing carriers with pre-installed bushings (one left, one right) and mounting bolts.

 These bushing brackets fit all 2001, 2002, 2003, 2004, and 2005 model BMW 325xi and 330xi.

Modern BMW's are beginning to leave the performance derived handling and power delivery in the past as the demand for more comfort and features rises. The stiff suspension components designed around having the best driving experience from a luxury car has been left for the M models and replaced with soft rubber bushings and mounts. Unfortunately, this is a good move by BMW to support the masses.

The obvious approach was to offer products so the modern BMW can be upgraded into the car the enthusiast desires, superb handling, control, and a direct delivery of power to the rear wheels. When you upgrade to our Delrin subframe mounts you reconnect that power with almost zero negative feedback.

The added appeal to someone looking to take one of these machines on the race track is Delrin can be used when solid mounts are needed and aluminum is not an option with strict regulations found in Grand-Am, BMW CCA, and other racing series.

Product features:

• Precision machined Delrin(TM) 150 bushings.
• Precision machined 6061-T6 aluminum inserts. 
• Class legal for any racing class that does not allow a solid subframe bushing. 

Performance Benefits:

• Eliminates subframe movement for more direct throttle and suspension  response. 
• Minimizes wheel hop due to subframe deflection and movement.

Rubber mounts in any position of a vehicle are usually designed with comfort and longevity in mind leaving performance as a sacrifice. This kind of sacrifice here at Turner just won't do, so we did what we do best and designed a solid monoball mount.

Our engineering team first wanted to tackle the issue with wear found on rubber mounts. Due to their combination of steel, rubber, and low mounting location, these mounts are a direct target for deterioration and failure. As they are positioned out in the open and exposed to the elements, bonded steel and rubber components inevitably hold moisture, separating as the steel bearing begins to rust. Our solution was to offer a rebuildable mount with a Teflon lined bearing for increased durability, combined with a blue anodized body and melonite coated bushing sleeves for corrosion resistance.

The performance side of these mounts is primarily found in the articulation allowed by the bearing. Rubber mounts do not allow for proper free damper movement, hindering shock performance. By eliminating the deflection found in factory rubber mounts and allowing full shock articulation, this solid monoball design eliminates slop and maximizes shock efficiency and performance, allowing for more predictable handling on the street or the track - with almost zero added noise, vibration, and harshness.

Replaces OE part #: 33526768544

Key Benefits:

• Monoball rear lower shock mount eliminates unwanted deflection, maximizing shock efficiency and performance.
• Allows full shock body articulation for low friction movement and reduced side loading and improved shock wear.
• Designed to work with stock non-M taper seat stud style shocks (not M eyelet mount type).
• Maintains OE shock position

Design features:

• Rebuildable using off the shelf bearings - these are the last rear shock mounts you’ll need to buy
• Includes new hardware
• Made in USA

Housing:

• Billet CNC 6061-T6 aluminum housing, type II anodized for exceptional durability and corrosion resistance

Bearing:

• FK WSSX14T teflon lined spherical bearing
• 440C heat-treated stainless steel ball, 1 ⅜” ball dia.
• 17-4 PH heat-treated stainless steel race
• Self-lubricating PTFE liners are chemically bonded to the inner diameter of the race to offer a very high load-carrying capacity with greatly increased dynamic wear characteristics.
• Static Axial Load Rating: 10,800 lbs.
• Rod End Misalign Angle: 6 degrees

Bearing inserts:

• CNC machined 1144 steel, heat treated and melonite coated designed to maximize ball articulation while offering exceptional durability and corrosion resistance.

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Engineered to perform, Powerflex performance polyurethane 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 steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

RTABs play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.
