The Powerflex E36/E46/Z4 Rear Trailing Arm Bushing Kit is the perfect replacement for the common RTAB failures on E36s, E46s, and Z4s – failures that can result in drastic rear suspension geometry changes and, in near-limit situations, potential loss of control. If you track your car, drive aggressively on the street, or have over 50k miles on the car – now is the time to replace!
Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques.Durometer is standardized per fitment and location, so you can rest assured knowing the design engineers have selected the optimal urethane hardness for this specific part.
Also known as toe bushings, these Powerflex polyurethane pieces are incredibly durable, and they’re legal for many stock and prepared racing classes.
E36 (1992-1999, except 318ti)
E46 (1999-2006, all)
Priced per pair.
FITMENT NOTE – Powerflex provides one part number for this fitment, which indicates E36 model cars. BMW uses the same part number for E36, E46, and Z4 (just like Powerflex), and the E36 part is correct for all of these applications.
