The latest BILSTEIN B3 range currently has almost 1,500 applications for steel springs alone, as well as a steadily growing number of air springs. As a result, the range includes high-quality OE replacements with a convincing price/performance ratio for almost all passenger car models available in Germany and other countries – from modern compact cars and SUVs to sports cars, luxury limousines and even classic cars.
BILSTEIN manufactures its B3 products precisely in accordance with the vehicle manufacturers’ technical specifications.
The range of coil springs includes models with pigtail ends as well as force-centre-optimised (KMP) and miniblock designs, with each type being suited to different applications and offering specific benefits. The barrel-like construction of miniblock springs, for example, ensures optimal comfort, especially on uneven terrain. Due to their curved shape, the force-centre-optimised springs are able to compensate for the transverse forces in the McPherson spring strut on the front axle and with their rounded end coils, pigtail springs represent the cylindrical design with the lowest installation height.
A common feature of all models is their perfect production quality – the highly fracture-resistant base material (high-quality chrome-vanadium or chromium-silicon steel) is additionally set several times after the forming process in order to avoid subsequent height loss during use. Naturally, BILSTEIN B3 coil springs also have the same excellent fit as the originals.
Another interesting alternative for modern suspension systems are the B3 air springs, which are manufactured in 100% original equipment quality (or even as original equipment) and are available for a constantly growing number of car models. While these have been designed for models in which the shock absorbers are installed separately, the B4 air suspension modules are the perfect “exchange partner” for combined air spring/shock absorber units.
Quality wise, they are true to the original — from the gaskets and air spring bellows through to the metal components.
No matter whether you need a classic coil or a high-tech air spring, BILSTEIN B3 suspension springs are always the best option when the old components are worn out. Since many customers are unable to independently detect minor damage such as spring breakage, rust formation on steel springs or initial leaks in air suspension systems, the workshops should offer regular suspension checks. Ultimately, once the vehicle is on the lifting platform, the trained eye can often spot problems at a glance.
