Control Arm Bushings for BMW 3 Series E46 (1999-2005)

Our sealed Monoball Rear Trailing Arm Bushings (RTAB) are the best solution for completely eliminating deflection and unwanted toe changes on the rear of the E36, E46, and Z4. While rubber and urethane bushings flex during load, the toe can change widely giving you nervous and unpredictable handling. These RTABs have a solid aluminum housing with a high-quality sealed OE bearing. These bushings were developed from years of competition use in various racing and HPDE events. There is simply no better RTAB unless your racing class rules prohibit the use of mono or spherical bearings.

The rear trailing arm bushings take a lot of abuse from acclerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car. We also offer a Delrin RTAB for cars that must conform to certain racing class rules. These sealed spherical bearings are the best at controlling rear toe alignment.

Our aluminum RTABs are very well made - high grade aluminum alloy and steel CNC'd out of a billet by an ISO 9001 certified manufacturer, each component is either hardcoated or nickel plated. While multiple manufacturers offer two piece designs, our research showed that a one piece bushing is a better design featuring a sealed bearing to keep contaminants out extending the life of the bearing.

The front control arm bushings are a key piece of the suspension. They are constantly in motion and take abuse from impacts, potholes, rough roads, and general cornering/wheel motions. To give a quiet and smooth ride, the bushings are made of rubber with a metal sleeve insert. But the rubber can only withstand so much abuse before they become loose and spongy. This results in vibrations and possibly a shimmy when driving. A visual inspection will usually confirm that there is too much flex in the rubber or the rubber has cracked and torn. And if you're installing new control arms, always install new bushings to avoid duplicating labor costs.

The E36/E46 rear trailing arm bushings (RTABs) wear out faster than any other bushing on the car. Worn RTAB will cause excessive toe alignment change and give a 'loose' or 'floaty' feeling in the rear handling. One of the reasons for this is that they over-extend during motion, stretching and twisting the rubber in all directions. These shims sit on either side of the bushing and limit the amount of extension from the bushing. Not only will you get more life from your RTAB but these will help stiffen the bushing during cornering. But during normal driving you will still have all of the comfort of the stock rubber bushings. These part about these bushings is how easy they are to install - simply slide them in place during your bushing install. They can be added to pre-installed bushings too by dropping the trailing arm and removing the cage around the bushing.

Works with stock rubber bushings only (not urethane or Delrin).

Bushings tends to wear over time and split or even break free from the internal sleeve, causing excessive movement and sloppy control feel. Meyle HD bushings are the perfect option to improve your suspension.

Control arm bushings 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.

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

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.
