Bilstein B8 Performance Plus Front Shock Absorber/Strut Insert for BMW E21 3 Series (1975-1984), Lowered Suspension - 34-186350

Bilstein B8 Uprated Front Damper Cartridge for BMW E21 3 Series | Part No. 34-186350

Give your classic BMW E21 the sharp, confident road feel it deserves with the Bilstein B8 Performance Plus front damper insert, part number 34-186350. Purpose built for cars running a reduced ride height, this short-stroke, gas pressure strut cartridge delivers precise control, tighter body control and superb stability without ruining everyday comfort. Pair it with quality lowering springs for a properly balanced, fast-road suspension package.

Engineered as an inverted monotube design, the B8 keeps damping consistent under hard use and resists fade on spirited drives. The shortened body preserves correct spring preload on lowered setups, so you get clean turn-in, less dive under braking and planted confidence at motorway speeds. If your E21 runs sport springs or a performance coil kit, this front strut insert is the ideal match.

What makes it stand out

• Short-stroke damper designed for reduced ride height and sport springs
• Inverted monotube construction for stiffness, precision and long-term durability
• Gas pressure technology for consistent, fade resistant damping
• Direct, communicative steering feel with improved mid-corner control
• Excellent B-road composure and motorway stability
