Chevrolet Pickup Suspension springs extend

Hello, I drive a C10 and am now almost finished with everything. But if I want to put it even deeper now, in front and back. It is clear that the springs have to be removed at the back. now to my question: I want to change the spindles in front through dropspindles and the springs, I inevitably need a spring tensioner for this, because I have already seen that a cart lifter is put on from the bottom of the shoulder and then the ball joint is unscrewed. n you could theoretically simply release the car lifter and remove the spring?! someone has experience with it? by the way thank you for the many answers to my andres topic, I have now just bought a 600 Holley with vacuumgetseuerter secondary stage and he drives like a one… because 650er I keep for further conversions on the motor thank you in advance
