Powerflex PFF5-4631 Front Shift Arm/Selector Rod Bush (Oval) - Polyurethane Shifter/Linkage Insert for BMW 4 Series F32 F33 F36 xDrive - Gearbox/Transmission Gear Lever Bushing - Replaces OE 25117507695

Transform your BMW 4 Series gear change feel with a polyurethane front linkage bush

Give your F32, F33 or F36 xDrive a cleaner, tighter gear change with the Powerflex PFF5-4631 front gear linkage oval bushing. By replacing the soft factory insert with high quality polyurethane, you reduce unwanted movement in the gear lever linkage for a crisper, more positive engagement on every shift. Ideal for spirited driving, track days and daily use alike.

Why this upgrade matters

• Snappier gear selection with reduced play and slop in the change rod
• More consistent, confidence-inspiring engagement under load
• Polyurethane resists oil, heat and ageing far better than rubber
• Long lasting performance that outlives tired OE inserts
• Backed by the Powerflex lifetime guarantee for peace of mind
