Review on Bilstein 21 030505 Replacement Suspension Cartridge by Regan Maez

As a result of using this suspension cartridge, I found that it was poorly manufactured and of subpar quality. The installation process was difficult and time-consuming, and after only a few months of use, the suspension began to show signs of wear and tear. The only redeeming quality was the initial improvement in handling and ride comfort. Unfortunately, this was short-lived, and I would not recommend this product to anyone in need of reliable suspension upgrades.
