What is normal preload for the 5th and 6th coils and which do you preload load first?Thanks

I like 3 rounds of preload on my 5th coil w/ 300lb spring.

the 6th coil is basically a buffer to keep you from ripping the torque arm off when you slam on the brakes. You want a spring that is soft enough to allow it to be spongy to the torque arm's needs. If you put too hard of a spring on it, it will act like its trying to bottom out or something. The preload on the spring should just be so that it won't move or move around on the perch when it's in its lower position. It will not help your suspension bite better or anything, just a safety deal.

We are very close to what RR has...we run 1/4" on a 325lb 5th spring and just keep the 6th spring from moving around. We run a 600 lb, thinking about dropping to a 400 lb spring for entry
