How can I figure out the spring rate when assist springs are installed with main springs?
Here is the formula for that. A=main spring B=assist spring For example, When Main springs (700 lbs) & assist springs (300 lbs) are combined, A X B 700 X 300 = = 210 A + B 700 + 300 You get 210 lbs of spring rate until assist spring completely binds. After that, you get 700 lbs spring rate. 7. How do I prevent (bow) on longer springs? Refer to question #2 8. What is the difference in progressive and linear springs? LINEAR Well linear spring theoretically keep the same spring rate regardless of stroke. If you have a 6kg/mm linear spring, if you compress it 10mm it should only take an additional 6kg to compress another mm. Therefore, if you compress a linear 6kg/mm spring with 60kgs of force, it will compress 10mm. Linear Spring Characteristics The benefit of a linear spring is consistency, meaning the weight transferring from side to side should be very smooth and controllable. After learning the cars dynamics, drivers can anticipate weight transfers and body roll more accurately. While
