Powerflex Poly Bush Set – Rear Bar 17.5 mm – BMW X3 E83 2003 to 2010

Looking to tighten up the back end of your BMW X3 E83 without spoiling ride quality? This Powerflex polyurethane rear bar bush kit in 17.5 mm is the simple, high-impact suspension upgrade that restores precision, boosts cornering confidence and keeps alignment consistent on British roads. Part number PFR5-4609-17.5 replaces BMW reference 33503404616.

Why this upgrade works

• Cleaner steering response and improved mid-corner stability
• Reduces roll and tightens rear chassis control for a more planted feel
• Maintains geometry for better tyre wear and predictable handling
• Durable polyurethane that resists age, heat and oil compared to tired rubber
• Designed for the clamp on the rear roll bar with a 17.5 mm diameter
• Road Series compound balances performance with comfort for daily use and fast road

We run Powerflex bushes on our own builds and our customers consistently feed back just how much sharper and more stable the X3 E83 feels after this swap. It is one of the best value suspension enhancements you can do.
