parabolic spring confusion

Parabolics shocks

Yes but parabolics work by flexing more and easier than stock springs allowing them to better smooth out bumps. You are not supposed to use limit straps with parabolics because they inhibit part of the normal parabolic spring movement. Also LRs tend to sit a little higher when on parabolics.

Shocks are supposed to be matched to the spring rate. The goal is to allow the spring to move and dampon spring rebounds so you don't end up with the body bouncing up and down on the springs. Stock shocks are designed to properly dampen stock spring movement and will not work properly with parabolics. Always check with the spring manufacturer to get their shock recommendations.

Ideally when the vehicle is at rest the shock should be mid way through its travel. BUT Series shock mounts are mounted closely together and a shock can easily reach its limit with parabolics and even with new stock springs. LR fixed this problem in 1983 by moving the shock mounts farther apart so longer shocks can be used. What people usually do with parabolics is mount a longer travel shock that allows increased lower articulation at the cost of upper articulation. Some folks cheat and fabricate new shock mounts that are farther apart than stock.

This has answered my questions. I should have searched. I figured this has come up before. Thanks

So, does this mean if you by a remanufactured frame for a Series III, 88 inch the mounts will be in the 1983 position since production ran until possibly the end of 1984 when they were replaced by the Ninety?
