PowerFlex Rear Sway Bar Bushing - 18 Mm - E24, E28, E32, E34, E36, E46, Z3, Z4

Product Details

If you’ve been chasing a vague, floaty feeling from the back of your BMW during hard cornering or aggressive launches, you're likely feeling the factory rubber bushings flexing under pressure. Over time, those OEM pieces turn to mush, leading to erratic toe changes and a car that feels like it’s steering itself from the back.

Enter the PowerFlex Heritage Series. Engineered from their signature Road Series polyurethane, this 18mm rear beam mounting bushing strikes the perfect balance between track-day precision and daily-driver civility.

Why the Crew Recommends This Upgrade

• Sharp, Predictable Handling: By drastically reducing unwanted deflection in the rear subframe/beam, this bushing locks down your suspension geometry. You get crisp turn-in and a rear end that follows the front without hesitation.

• The "Goldilocks" Polyurethane: PowerFlex’s Purple compound is formulated for enthusiasts who drive their cars on the street but still want maximum performance. It’s significantly stiffer than stock rubber, but engineered to absorb harsh road vibrations so your teeth won't rattle on the commute.

• Built for the Long Haul: Unlike rubber that rots, cracks, and softens when exposed to oil, salt, and road grime, this poly bushing is virtually indestructible. It’s the last time you'll ever have to replace this part.

• Easy Installation: Designed to fit perfectly into the 18mm housing, saving your knuckles and your patience in the garage.

Fitment Note: We recommend measuring your rear factory or aftermarket sway bar to determine which size of bushings are required for your vehicle. Sway bar sizes can differ depending on factory suspension packages and aftermarket sway bar brands.
