Bilstein B8 24-178525 Rear Shock Absorber / Damper for BMW 5 Series F10 & 6 Series Gran Coupe F06 - Short-Stroke Monotube Gas Shock for Lowered & M Sport/Sport Suspension - Performance Rear Strut Upgrade

Bilstein B8 24-178525 Rear Shock for BMW 5 Series F10 and 6 Series Gran Coupe F06

Looking to tighten up the rear end of your BMW without ruining day-to-day comfort? The Bilstein B8 part number 24-178525 is a short-stroke, gas-pressurised rear shock specifically calibrated for cars on lowering springs or factory sport chassis. It delivers sharper response, flatter cornering and rock-solid stability on UK roads, making it a superb upgrade for the BMW 5 Series F10 and 6 Series Gran Coupe F06.

We have fitted this unit for our own customers and the transformation is immediate: cleaner turn-in, improved traction out of bends and far better control over undulations. Pair it with quality lowering springs for a stance that looks right and a ride that feels planted.

What you will notice

• Short-stroke design keeps lowered cars in the ideal damping window for composed control
• Gas-pressurised monotube construction for consistent, fade-resistant performance
• Reduced squat and roll for a more agile, confidence-inspiring rear axle
• Precise, sporty feel that still rides well on British B-roads and motorways
• Perfect partner for M Sport style setups and aftermarket lowering springs
• Direct-fit replacement that refreshes tired OE damping
