Also, "clean usable controllable"? As opposed to...? I am also slightly confused on the full bump pic. I see what looks like a single leaf stack, and the full droop has what looks to be at least a 6 leaf pack.
sodirty answered the 1 leaf question.. And the spring pack that we are using is a 10 leaf pack.
Also, a prime example of fluffed numbers was rolled into my shop yesterday. This particular front end kit has a claimed 13.75" of front wheel travel. In reality it has 12.25", that 12.25" of travel is not all usable since at full droop it binds something fierce.
Are there no street legal fuel cells that would fit a Raptor?
It really depends on your local emission laws. Out here you would need to keep your charcoal canister and your stock filler to still pass.
