Bilstein 34-003343 Front Strut Cartridge for BMW E30 (45 mm Housing)

Transform the way your classic 3 Series grips, turns and puts power down. The Bilstein B8 Performance Plus front insert, part number 34-003343, is a short-stroke, gas-pressurised, inverted monotube cartridge engineered for reduced ride height and factory sport chassis setups on BMW E30 models from 1982 to 1994. If you’re chasing razor-sharp steering, tight body control and real confidence on fast B-roads, this is the proven upgrade.

We run these on our own E30 builds and our customers love the balance: taut, controlled damping without ruining daily comfort. It’s a superb choice for fast-road cars and occasional track-day use, especially with performance lowering springs.

Why it belongs on your E30

• Short-stroke design optimised for reduced ride height and OE sport springs for proper travel and control
• Inverted monotube construction increases front-end rigidity for crisp steering response
• Gas-pressurised damping delivers consistent performance and excellent stability under hard use
• Precision valving tuned for the E30 chassis for predictable handling and grip
• Pairs brilliantly with popular E30 lowering spring sets for a cohesive fast-road setup
• Durable build quality from Bilstein for long-term, fade-resistant performance
