BILSTEIN B3 Front Coil Spring for Opel Signum, Opel Vectra C

OE replacement springs in OE quality

Bilstein B3 springs are the first choice to replace the original springs. They are made to the vehicle maker's specification, with exactly the same tuning, durability and quality as on a new car, plus high stability and outstanding durability.

The B3 range at a glance

B3 coil springs are available for a large number of makes and models, each developed and made exactly to OE specification. With so many vehicle-specific versions, workshops can find the right spring for nearly every model.

When comfort, safety and original quality count

Small car, saloon, estate or SUV – the B3 comes in a huge number of versions for maximum vehicle coverage. Its vehicle-specific characteristics give the right balance of comfort, safety and handling in every class, which makes it the first choice for workshops that want original quality and wide availability.

Product benefits

Developed and made to the original maker's specification, B3 springs give the same comfort, safety and precise fit as the OE springs. They install exactly like the OE part with no extra work – quick and cost-efficient.

• Built to OEM specification
• High break resistance from high-grade chrome-vanadium and chrome-silicon steels
• Holds its height: hot setting after forming prevents height loss
• Long life from optimised surface compaction and coating
• Available for a wide range of makes and models

What makes B3 stand out

• 100% OE standard and a new part: every B3 spring follows the OE specification down to details such as pigtail ends, mini-block shapes and side-load (centre-of-force) designs.
• Very high break resistance from premium chrome-vanadium or chrome-silicon steel – OE quality that clearly raises driving safety.
• Targeted hot setting after forming prevents height loss, so ride height stays constant and the car stays safe and stable over the long term.
• Optimised surface compaction and a high-quality coating protect against corrosion and fatigue for a long life, even in tough conditions.
• Covers a large number of makes and models, from small cars to SUVs, always in OE quality.
• Each spring is matched to the exact equipment and model variant, for original comfort and correct balance with the damper, as on a new car.

B3 for almost every vehicle

• OE replacement for cars of every class, from small cars to luxury models, with vehicle-specific characteristics for as-new comfort, safety and handling.
• Also available for SUVs and vans – robust, firm and matched to higher vehicle weights for lasting stability and safety.
• Works with OE replacement dampers such as the Bilstein B4, for a well-matched system, precise response and fitting without adjustment.
• The fix for broken, worn or sagging springs: fully restores ride height, stability and comfort.

Frequently asked questions

Which B3 springs can I fit (e.g. standard or sports suspension)?

B3 springs are made exactly to OE specification so the car's original handling is kept. Always choose by vehicle, because damper, spring and top mount are tuned to work together.

Can I use the reinforced B3 springs on my car?

Only if the car has the matching equipment. Fitting them to the wrong car can change ride height and how the suspension works.

Why does the suspension need enough spring preload?

Preload keeps the spring firmly seated in every situation, even at full extension. Axial play is checked here – an important point, also for roadworthiness inspections.

How are Bilstein's OE replacement parts named?

B1 = OE replacement service parts (top mount, bump stop, protective tube) and, for air suspension, the compressor. B3 = OE replacement springs (coil spring or air spring). B4 = OE replacement shock absorbers and air suspension modules.

My shock absorbers are worn. Should I replace the springs too?

If the springs have done a lot of miles, yes – a new damper only gives its full performance, safety and comfort with a working spring.

My springs are broken – which spring is right?

B3 springs are available for a large number of makes and models; Bilstein's catalogue lists the exact 1:1 replacement for each car.
