European-engineered hardware competing with American innovation: Bilstein 5100 vs. Fox 2.0 shock comparison proves that the latter is worthy of the higher price.
An Overview for a Start
There are plenty of suspension-performance and -modding forums on the net that engage in discussing the comparison in-between the Bilstein 5100 and Fox 2.0 shocks. Fortunately, there are lots of real-world automotive enthusiasts, who have been testing the aforementioned shock types up on the same SUVs and pickup trucks. These drivers have been engaging in plenty of off-roading and 4x4ing, while pushing their vehicles to the absolute limit. The following article is a synopsis of their exploits, forthcomings, and experiences, during and after thousands of miles driven up on desert floors, muddy roads, and sandy dunes.
The Tech Specs Begin
There’s plenty of feedback, which is received from vehicle owners, warranty requests, engineering specs, and so on, used in the Bilstein 5100 vs. Fox 2.0 comparison table below, thus pointing out both pros and cons of these shock types. The absorbers are engineered featuring monotube designs, with final components being charged with high-pressure Nitrogen gas. Both the 5100s and 2.0s come with durable internal pistons, which are connected to the rod, designed to push the shock fluid / oil through the valves, while regulating damping. Both of these products are nothing short of the apogee of modern-day shock absorber technology, implemented into metals, plastics, and alloys.
Data Table
|
| Body Size | Body Material | Finish | Rod Size | Rod Material |
| Bilstein 5100 | 49.53 mm. / 1.95 in. | Steel | Zinc | 1/2” | Steel / Chromium |
| Fox 2.0 | 50.80 mm. / 2 in. | Aluminum | Anodized | 5/8” | Steel / Chromium |
More Tech Specs to Follow
As manufacturing companies, neither Bilstein nor Fox are willing to reveal the exact pressure in pounds per square inch that their final-user products are charged with. Although, we can tell with considerable certainty that both manufacturers use high-quality Nitrogen gas, with the Bilstein 5100 series being pressurized up to 200 and the Fox 2.0 series up to 300 PSI. Here, the latter is a clear winner, while ensuring a firmer ride because of higher internal pressure, raised to guarantee better damping qualities. The final decision about which shocks to install is only yours, with most suspension enthusiasts preferring the Fox 2.0 types for their firmer ride.
Differences in Design
Bilstein 5100s are created specifically for those vehicle owners, who drive aplenty of paved roads, while only rarely getting off the beaten path. The series will work for weekend warriors, who prefer to drive on concrete and asphalt, while also venturing out onto countryside roads, forest trails, and sandy beaches. Fox 2.0s are designed to be used during hard 4x4ing and off-roading, with the SUV or pickup truck’s suspension being aggressively pushed to the limits. They come with durable aluminum bodies, which offer lighter weight and considerably better dissipation of by-product heat. The Fox 2.0 series shocks will radiate the waste heat into the atmosphere, while remaining cool for much longer, thus ensuring better performance.
Plenty Depends on the Price
If you are wondering exactly which shock is better in the Bilstein 5100 vs. Fox 2.0 comparison, while planning on using them in your SUV or pickup truck, then you need to address the issue of the Fox shocks’ substantially higher price. These components are much more expensive than their Bilstein counterparts, and can sometimes cost almost twice as much. You can expect to cash out about $300-400 per set of Bilstein 5100s, with the Fox 2.0s price tag being as much as $500-600 per set. In general, majority of suspension-performance and -modding fans agree that you’ll get better performance for the money paid from the latter shock absorber series.
Conclusion
Both of the shock types in the Bilstein 5100 vs. Fox 2.0 comparison come from reputable manufacturing companies, which are renowned the world over for their quality products. Regardless of exactly what your preference may be, either one of these shocks is a superb choice. If you don’t have the necessary funds, while preferring to drive over well-paved roads instead of tearing through the mud, then Bilstein 5100s are a sure way to go. If you are capable of affording the higher price tag, while wanting to engage in plenty of off-roading, camping, 4x4ing, etc., then Fox 2.0s are surely worthy of being purchased and installed.
