Frequently Asked Questions
Why do rear adaptive shocks fail?
Rear shocks see more stress from load carrying, potholes, and speed bumps. The electronic valve solenoid inside can wear out or the shock body can develop leaks from the added complexity.
Can I feel the difference between a good and bad adaptive shock?
Yes. A failed adaptive shock will feel either too stiff or too soft compared to the working shocks. The difference is especially noticeable over bumps and during cornering.
Is it worth converting to standard shocks?
This depends on your priorities. Standard shocks are cheaper but you lose the ability to adjust ride quality. Many owners of high-mileage luxury vehicles make this conversion to reduce costs.
