Powerflex PFF5-1903-23.6 Front Stabiliser Bar Bushings – BMW 1 Series F20/F21 xDrive – 23.6 mm Pair

Give your xDrive BMW 1 Series the precise front end it deserves. This Powerflex bushing set replaces the soft factory mounts on the front stabiliser bar, tightening chassis control for a more connected, confidence-inspiring drive. Part number PFF5-1903-23.6 is the 23.6 mm D-bush size for F20 and F21 xDrive models, supplied as a matched pair for the front bar.

Built from performance polyurethane, these uprated bushes keep the bar located under load, holding geometry steady so the tyres work harder for you in fast direction changes and on uneven British roads. Expect crisper steering input, flatter cornering and a calmer front axle under braking, with excellent control of noise, vibration and harshness. Backed by Powerflex’s lifetime warranty, this is a fit-and-forget upgrade that outlasts standard rubber.

Why enthusiasts choose this upgrade

• Sharper turn-in and improved road feel for your AWD 1 Series
• Reduced body movement and more consistent front-end grip
• Polyurethane resists wear and ageing far better than OE rubber
• Reliable handling on fast road use without unwanted cabin harshness
• Great value performance mod with long-term durability

We have installed these on customer cars and our own demonstrators with consistently positive feedback. Drivers report a tighter, more responsive front end and greater confidence in wet and dry conditions.
