There are many variables when choosing the best shock or strut for your car. Driving conditions, age of your car, tires, tire pressure, and many more. Shockwarehouse offers you a handy comparison chart to help you make this decision. Take a quick look at the chart linked above but here are some important notes mainly highlighting the difference between Monotube and Twin Tube Shocks
In our opinion, monotube high pressure gas units offer the best dampening power, performance, and handling.
This does not mean you always need performance. For average driving, a twin tube low pressure unit is still a good choice.
