Bilstein introduces B1, B3 and B4 range universal spare parts

Bilstein, the Ennepetal-based shock absorber, suspension and spring specialist, has added roughly 220 new part numbers to its B1, B3 and B4 universal spare parts product lines. The company added more than 70 applications to its Bilstein B1 range of accessories in the latter half of 2012; 90 parts numbers were added to the Bilstein B3; and an extra 50 new applications were also added to the Bilstein B4 range.

The B1 programme covers accessory parts such as bearings, mounting parts, bump stops and dust tubes. The company recommends replacing the BILSTEIN B1 accessories each time the shock absorbers are replaced due to the high-stress levels to which the mounting parts are subjected, giving increased damping power to the car.

Bilstein B3 springs are manufactured to the precise specifications of each associated manufacturer. The coil springs for the Mercedes-Benz M-Class (W163 and W164) have been produced using the latest technical designs such as pigtail ends, mini-block form or side-load design springs. The base material (chrome vanadium or chrome silicon steel) is repeatedly hot-set after the forming process to avoid later height losses. A special shot-blasting technique is used to shot-peen the springs which then have a flexible coating of epoxy powder applied for a long and active service life.

The gas pressure technology of the Bilstein B4 universal spare part shock absorber makes a tangible improvement to driving stability and overall safety, especially in older models that have covered many miles, the company says. The shock absorber is designed to offer a longer life even when subjected to heavy-duty use.
