BMW Suspension Bushings & Mounts

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:
