Don’t fall for the myth — the 4600 Series is your best bet for factory-height vehicles.
If you want to keep your truck or SUV at its stock ride height, the Bilstein 4600 (B6) Series is the recommended option.
Designed as a direct-fit replacement for factory shocks, the 4600 Series delivers the ideal balance of comfort, control, and durability. Its monotube design and velocity-sensitive, digressive piston adjust to changing road conditions, giving you a smooth, confident ride—whether the vehicle is loaded or unloaded.
Common Misconception: Is the 5100 More “Heavy-Duty”?
There’s a widespread belief that the Bilstein 5100 Series is stronger or more heavy-duty than the 4600. This is false. Both use the same premium internal components and high-quality construction. The key differences are:
-
Length: The 5100 is longer to accommodate suspension-lifted vehicles.
-
Finish: It features a zinc-plated exterior for improved corrosion resistance in off-road conditions.
The 5100 Series is purpose-built for vehicles that have been lifted and need extended shock travel. It is not intended as an upgrade for stock-height applications.
What Should I Use for a Stock-Height Vehicle?
For daily driving, towing, and all-around performance on a factory-height truck or SUV, the Bilstein 4600 Series is the superior choice. Stick with 4600s to get the most out of your stock suspension setup.
