The difference is that JKS is a softer puck. You won't get the advertised amount of lift, nor will the loading be even across the body mounts. This can cause rippling in the sheet metal. Savvy is an aluminum puck, which raises the body, while still allowing the factory body mounts to work correctly.
I've seen the JKS buldge you've referred to in other posts, dont doubt the assessment... Have you or do you know others that have taken measurements to see how much compression occurred over time?
The compression and bulge occurred immediately on mine. I think I'm getting a little over an inch. If I wanted less, I would just keep tightening.
I installed a jks 1.25 bl. It works fine. With that being said if i ever do it again I will go with solid aluminum risers. Like savvy or M.O.R.E.
It isn't so much that it happens over time it is that it is variable from the start. Want less lift? Just tighten them a bit more. What most overlook is the tub and frame are a unitized structure that are stronger as a sum of the parts than each part by themselves and you don't want that connection compromised by a sponge.
Raising the side body mounts and possibly the rear of the frame is another reason I want to switch to a hard puck. I can't see how the remaining stock mounts could be evenly loaded with the JKS spacers.
Very nice. GenRight is likely the plan. It seems cleaner and a bit more foolproof than if I try to reuse the stock mounts.
Depends on how good you are.
Before I convinced Tony to make the raised versions, I used to do it this way.
