What is the price of an ATV spring?
It depends on your vehicle weight and the motion ratio you need and also the suspension play you need. For vehicle weight of 200 and play of 8 8inches you might need spring rate of 130 to 150 kg per inch.
How do you calculate the natural frequency of a suspension?
f = Natural frequency (Hz) K = Spring rate (N/m) M = Mass (kg)
- 0.5-1.0Hz Passenger cars, typical OEM.
- 1.0-1.5Hz Typical lowering springs.
- 1.5-2.0Hz Rally Cars.
- 1.5-2.5Hz Non-Aero racecars, moderate downforce Formula cars.
- 2.5-3.5Hz Moderate downforce racecars with up to 50\% total weight in max downforce capability.
What is suspension frequency?
Suspension frequencies are the rate (in cycles per unit of time) that a spring oscillates after applying a load (or hitting a bump). A suspension with stiff springs and a high frequency will oscillate more quickly than the same car with soft springs.
What shock spring do I need?
For example, if your shock stroke is 2″, your max spring free length is 130mm and your spring rate is 450lbs, you need a spring that is 2.25″ x 450Lbs x 125mm (if you don’t see a spring that has the exact stroke of your shock you can use a spring with a longer stroke, as long as the free length will fit).
How is spring rate calculated?
To calculate the amount of spring rate you will need on order to meet your working loads, simply divide the load you will be applying on your spring by the distance you expect your spring to travel or compress under that load.
How do you choose spring coilovers?
Rules of Thumb
- Preload. Preload at the coilover should be between ½” and 6” to prevent the springs from coming loose and to ensure proper droop, wheel rate and bottoming control.
- Coilover Dual Rate Nuts. In a dual rate coilover setup, the softer spring should not be less than 70\% of the stiffer rate.
- Longer Lower Springs.
What determines a coil springs stiffness?
The amount of coils on a spring also determines the stiffness of a spring. The less coils you have, the stiffer your spring will be. In the case of a torsion spring, less coils give you more torque but less travel. In the case of a compression spring, it is based on the pitch in between its coils.
