Powerflex Polyurethane Rear Anti Roll Bar Bushes 14mm (Pair) - PFR5-1913-14 - BMW 1 Series F20 F21 xDrive ARB/Sway Bar Upgrade

BMW 1 Series F20 F21 xDrive 14 mm Rear Stabiliser Bar Bush Kit — Powerflex PFR5-1913-14

Transform the way your BMW turns in and tracks through bends with this rear stabiliser bar bush set from Powerflex. Engineered for the BMW 1 Series F20 and F21 xDrive, this 14 mm mounting bush upgrade keeps the rear bar precisely located for confident, repeatable handling on road and spirited drives.

The performance-grade poly material resists deflection far better than tired factory rubber, so the rear axle stays composed under load. Expect flatter cornering, sharper responses and improved stability without a harsh ride. It is a direct-fit replacement designed to last, delivering consistent performance mile after mile.

• Noticeably flatter cornering and improved rear-end control
• More accurate steering feedback with reduced body movement
• Durable compound resists oil, heat and road grime for long service life
• Helps maintain tyre contact and can reduce uneven wear
• Backed by the Powerflex Lifetime Warranty

Why this upgrade

If your BMW feels loose at the rear, wanders under braking or rolls more than it should, worn rubber mounts are a common cause. This Powerflex bush kit tightens the rear chassis, giving the consistent behaviour enthusiasts want from a suspension refresh, stabiliser bush replacement or handling upgrade.

At MJ Modifications we fit these regularly on customer cars and the feedback is consistently positive for daily driving and fast-road use. Reliable, precise and cost-effective compared with repeatedly replacing standard rubber.
