Powerflex PFF5-4631 Shift Arm Front Bush (Oval) for BMW 1 Series F20 F21 Road Series Polyurethane Gear Selector/Shifter Linkage Replaces OEM 25117507695

Powerflex PFF5-4631 Poly Bush for BMW 1 Series F20 F21 Gear Change Linkage - Oval Type

Transform the way your BMW shifts with this uprated front bush for the gear change linkage. Powerflex part number PFF5-4631 replaces the soft factory item and locks down the selector mechanism for a cleaner, crisper gear change. It is the ideal upgrade for drivers who want a tighter, more connected shift without sacrificing day-to-day comfort.

• Reduces slack and play in the selector mechanism for precise, positive engagement
• Urethane construction resists oil, heat and road grime far better than rubber OE parts
• Stable, consistent shift feel in all temperatures and driving conditions
• Direct-fit replacement for OE reference 25117507695 with no modification required
• Perfect for daily use and spirited road driving where durability and feel matter

Why this upgrade works

The standard bush softens over time, introducing vagueness into the gear lever. This high-performance poly bush supports the selector rod and reduces unwanted movement in the linkage, sharpening shift gates and improving feedback through the lever. Expect more confidence on every change and long service life compared to ageing rubber.
