Powerflex PFF5-701 Polyurethane Front Arm Bush/Bushing for BMW 5 Series E60 E61 & 6 Series E63 E64 (M5/M6) 2003-2010 - Radius Rod/Thrust Arm/Tension Strut/Caster/Wishbone Control Arm to Chassis (Forward Lower) - Replaces OE 31126765992

Powerflex PFF5-701 Poly Bush Set for BMW E60 E61 E63 E64 inc M5 and M6

Transform front-end precision on your BMW with the Powerflex PFF5-701 polyurethane bushings. Designed for the forward lower arm to body position on the front axle, these uprated poly bushes replace the soft factory rubber with a durable, performance-focused compound that resists flex. The result is crisper steering response, improved stability under braking, more consistent alignment and better confidence on fast road driving, all while remaining perfectly usable for daily use.

Key benefits

• Sharper turn-in and more direct steering feel
• Reduced arm deflection for stable geometry under load
• Greater braking stability and improved front-end grip
• Helps minimise uneven tyre wear by keeping alignment true
• Long-lasting polyurethane construction that outlives standard rubber

We run these bushes on our own cars and customer builds at MJ Modifications, and feedback has been consistently positive for road and spirited use. If you want an immediate and noticeable handling upgrade without adding harshness, this is a smart first step.
