Powerflex Rear Stabiliser Bar Bushings 14 mm for BMW 4 Series F32 F33 F36

Part number: PFR5-1913-14

BMW OE reference: 33556853475

Sharpen the back-end response of your BMW 4 Series with this pair of Powerflex polyurethane rear stabiliser bar mounts in 14 mm. These precision-engineered bushings replace the soft factory rubber, tightening the rear axle, improving turn-in, and helping the suspension keep the tyres planted. Expect crisper feedback, reduced roll, and consistent handling on fast road use.

We run these on customer cars and our own builds at MJ Modifications, and the difference in stability and steering feel is immediately noticeable. Backed by the Powerflex Lifetime Warranty, they are a fit-and-forget upgrade for road and track.

Why upgrade to polyurethane bushings

• Uprated compound resists deflection versus OEM rubber for more precise chassis control
• Enhances rear bar effectiveness for flatter cornering and better grip
• Improves braking stability and mid-corner confidence by reducing unwanted movement
• Durable and long lasting, maintaining performance far longer than standard bushes
• Designed to limit NVH while delivering a taut, connected driving feel

Fitment and compatibility

Suitable for BMW 4 Series F32 (Coupe), F33 (Convertible) and F36 (Gran Coupe) equipped with a 14 mm rear bar. Please measure your rear bar diameter before ordering to ensure correct sizing.
