PFR5-4609-14BLK - PowerFlex Rear Sway Bar Bushings - 14 Mm - E60
PowerFlex Rear Sway Bar Bushings - 14 Mm - E60
If you are chasing tenths on the stopwatch, compliance is the enemy. Upgrading to the Black Series 14mm rear sway bar bushings stabilizes the rear axle under aggressive trail-braking and mid-corner transitions. It's an essential, cost-effective upgrade for any dedicated track car or weekend time-attack build
Engineered for drivers who demand absolute precision, the PowerFlex Black Series Rear Sway Bar Bushing (14mm) is a track-ready upgrade designed to eliminate suspension deflection and optimize chassis balance.
Standard rubber bushings flex under heavy cornering loads, causing unpredictable dynamic toe and camber changes. The Powerflex Black Series is specifically formulated for motorsport, utilizing a specialized 95 Shore A polyurethane compound. This delivers maximum control, sharper turn-in, and highly predictable rotation under extreme track conditions.
Key Technical Features
Motorsport-Grade Compound: Molded from 95 Shore A durometer polyurethane, offering up to 80% more resistance to load than factory rubber.
14mm Precision Bore: Engineered for a zero-tolerance fit on standard or aftermarket 14mm rear sway bars, maximizing bar efficiency.
Advanced Lubricant Retention: Features internal knurling and grease retention grooves to ensure lifetime lubrication and noise-free operation.
Black Series Durability: Highly resistant to oil, fuel, road salt, and ozone—built to endure the harshest racing environments.
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.
