Bilstein 4600 Overview
Bilstein 4600 shock absorbers are designed to work with Jeeps, SUVs, and trucks with factory height. They have a patented design that offers high damping capacity, helping your vehicle to perform consistently on different types of surfaces.
They come with a high-quality steel body, making them extremely resilient and long-lasting.
Features
Bilstein 4600 shock absorbers feature a monotube-gas pressure technology. It comes with digressive valving functionality that allows the shock absorber to react to changing road conditions instantly for maximum control and comfort.
The Bilstein 4600 has a simple painted coating finish that protects it from rust decently. However, it’s not as good as the zinc-plated coating that the Bilstein 5100 features.
Additionally, you’ll also get high-quality vulcanized rubber bushings with Bilstein 4600 shock absorber. They reduce the vibration between parts and the transmission of shock to increase the product’s lifespan.
Another great feature that I loved about this model is the ease of installation. The shock absorbers come completely assembled, and ready to go on the vehicle. Lastly, the Bilstein 4600 series comes with a limited lifetime warranty to protect your investments.

The next big difference between the two products is that the Bilstein 5100 features a more durable and reliable zinc-plated finish. The Bilstein 4600 shock absorber series comes with a painted coating that doesn’t perform as well as Bilstein 5100 over time.
