Turner Motorsport BMW F22 F23 F30 F32 F33 F36 Front Lower Control Arm / Thrust Arm Tension Strut Monoball Spherical Bearing Bush Upgrade - Hydro Bush Delete Ball Joint Conversion for Sharper Steering & Brake Shimmy Fix - Polyurethane Bush Alternative

Front lower control arm upgrade for BMW F22, F23, F30, F32, F33, F36

If your F Series 2 Series, 3 Series or 4 Series feels vague on turn in, shimmies under braking or scrubs tyres prematurely, the culprit is usually the factory hydro bush in the front tension strut. This direct-fit spherical bearing conversion from Turner replaces the soft, fluid-filled insert with a sealed ball joint assembly that resists flex, stabilises geometry and transforms steering feel on the road and on circuit.

Why this precision joint is a game changer

Turner engineered this solution to deliver crisp response without the usual noise or harshness. It uses an OEM-style sealed and pre-greased ball joint for exceptional durability, housed in a CNC machined 6061-T6 anodised aluminium body with a knurled outer surface for a secure press fit. Stainless inserts ensure an accurate interface and long service life in all weather conditions.

• Instant, precise steering input and improved front-end bite
• Stronger braking stability with reduced wobble and judder
• Holds alignment under load for more consistent tyre wear
• Low friction movement with no binding and minimal NVH
• Maintenance free sealed joint for long-term reliability
• Corrosion resistant materials throughout
• Direct press-in replacement, no modification to the arm required

Fitment
