Caster

so i am a little confused about caster. Mine is set at 5.0 ds and 5.5 ps. If I bump it to 6.0, am I moving the wheels toward the bumper?

 

If you're increasing caster with the UCAs, you're moving the top of the wheel toward the cab. If you're adjusting by swapping out LCAs you're moving the bottom of the wheel forward. The most common is the UCA adjustment.

 

I installed Camburg UCA’s. So if I increase the caster to 6 from 5 I am moving the tire/wheel toward the cab?

 

My understanding (Minus the adjustable SPC arms) is that the caster correction is built into the aftermarket UCA. That is what will initially move the wheel closer to the cab over using the stock UCA. But making adjustments to caster on the truck would be through the LCA mounting bolts. Therefore increasing caster though the LCA bolts would move the wheel slightly forward.

That's how it works in my head anyway...

 

What @OBXTundra said above is correct.

 

Thank you. That helped me understand it more. That explains why I rubbed the BM on the DS and not the PS.

 

Thank you.
