Vehicle rake & effects on caster

I don't see this mentioned much at all.. With all the numbers about "what is ideal caster numbers" for a lifted truck, the vehicles rake is never asked or mentioned. Leveling the truck out is going to increase the amount of caster the vehicle has..

So with a stock truck with 1.5" of rake, leveling the truck will change the castor by the amount (in degrees) the vehicle's chassis was moved. So this would mean RCSB would get more caster for leveling than would a DCLB.. Interesting I thought..

Why isn't this discussed more/mentioned/factored into what actual ideal caster amounts should be?

 

In my mind it makes sense what u say bc the caster in relation to the uca and lca is not changing in this scenario but the caster in relation to the road is....

This pretty much answers my question. Thanks!

 

I know...zombie thread. But, it has a good searchable title.

Rake does affect caster.
This is for Lexus and FWD, but you get the idea.
