Makes sense, AEV tries to keep close to factory rake, clayton takes about half the factory rake out.My experience - I ran the AEV 3-inch coils with Clayton arms, Teraflex control arm brackets, and Fox 2.5's. The ride is good, soft-ish, so I needed to increase dampening on the shocks. For my application, I ran into a concern where the lift from the coils was closer to what I've seen for a 2-inch vs 3-inch and the rake was really pronounced. I put a one-inch Teraflex spacer up front and it was better, but still had a good rake to it. My application was not a constant load (towing). I've seen these hi-cap coils on a JT with a SmartCap installed and that did not even it out much. YMMV, but they can definitely hold weight.
In the end, I went to COR's 3.5-inch hi-cap coils in the rear with the 3.5's up front and that works for what we're trying to do. The ride is definitely firm with the Clayton coils, but I can account for ride with the shocks.
Roger that, After talking with AEV and Clayton, they were both looking at keeping the factory rake in the JT with their high-capacity springs, but that might be at two different points (loaded vs unloaded). That said, there was quite a bit of difference of height in the rear when unloaded between the two sets (F&R). The coil designs are different and the free length between the two are a lot greater than a half-inch. The AEVs are what I'd consider dual rate vs triple on the Claytons, as disclosed.
