Let me first presence that I am not a "Shock-ologist" but this article can provide a very basic understanding of bypass shocks. Generally Bypass shocks are more geared to racing applications, but they have migrated to the more average citizen builds as well.
What are Bypass Shocks and do I need them?
Bypass shocks are a type of shock absorber that features external tubes with adjustable bypass valves. These valves allow you to control the flow of oil through the shock, providing a wide range of damping adjustments. This design enables you to fine-tune your shocks to suit different driving conditions and terrain types.
In my opinion, I don't think the average builder needs bypass shocks. Most Jeep/Truck builders spend a lot of time on pavement, and low speed trail applications that don't require a bypass shock. Companies like Rock Krawler provide lift kits that include springs and shocks, pre tuned to work together for your application.
However if you desire high speed desert runs, or offroad racing, a bypass shock can provide a significant tuning advantage.
How to Tune Internal Bypass Shocks
1. Start by adjusting the compression and rebound settings on your bypass shocks. Compression controls how the shock absorbs impacts, while rebound controls how quickly the shock returns to its original position.
2. Test your shocks on different types of terrain to determine the optimal settings for your vehicle. Make small adjustments and take note of how your vehicle responds to each change.
3. Pay attention to how your vehicle handles bumps, jumps, and corners. Adjust the bypass valves accordingly to improve stability, control, and comfort. By dialing in the right settings, you can enhance traction, reduce body roll, and minimize harsh impacts. Properly tuned bypass shocks can also increase the lifespan of your suspension components and tires.
4. Fine-tune your bypass shocks based on your driving style and preferences. Some drivers prefer a softer ride, while others prefer a firmer, more responsive feel. Consider the frequency of high speed desert runs, street driving and slow speed rock trails when adjusting your shock tune.
In conclusion, properly tuning your bypass shocks is a critical step in optimizing your vehicle's offroad performance. By understanding how to adjust compression and rebound settings, testing your shocks on different terrain, and fine-tuning based on your preferences, you can achieve the perfect setup for your offroad adventures. Take the time to tune your bypass shocks properly, and you'll be rewarded with a smoother, more controlled ride on even the most challenging terrain.
