SDW Rear Trailing Arm Bearings

$265.00

We did a lot of searching and found that the Snycro Design Works' RTAB is the best rear trailing arm monoball bearing on the market. While at home on the street, this bearing is designed for track duty. Update and improve the rear suspension in your E36, E46 and Z4 by eliminating binding and deflection and by adding precision and longevity with the SDW RTABs.

Why upgrade your rear trailing arm to a bearing?
The trailing arm on the E36/E46/Z4 rear suspension attaches to the chassis just in front of the rear tire. The arm curves around the wheel, creating a pivot point which maintains toe-in as well as fixing the position of the wheels, front to rear. A stock rubber bushing wears over time, allowing deflection in the joint. The problem is compounded by performance upgrades such as increasing engine horsepower, increased grip of sticky tires and improved braking systems. By maintaining precise control of the trailing arm, more aggressive alignment settings may be run, resulting in the car handling better without concern of 'rear steer' condition as a result of worn bushings. SDW RTABS offer a range of multi-axial movement, where OEM bushings only pivot on a single axis, similar to a gate hinge in motion. OEM bushings, even when new, allow more deflection than preferred for optimal performance and have a limited service life.

What makes Syncro Design Works RTAB’s worth the increased price point?
Syncro Design Works Rear Trailing Arm Bearings use a high quality OE developed monoball bearing, designed for long-life while offering full articulation for optimal suspension geometry. The bearings are lubricated and sealed for maintenance free operation, which makes them the last RTAB that vehicle will ever need. SDW's' own 410hp shop track/street car still has the original prototype bearing installed in 2009, with no measurable toe deflection. SDW RTABs are precision CNC machined and anodized to protect against corrosion, moisture and salt spray. They come fully assembled ready to install.
