castor angle on 6.5 in. lift ??

teraflexed · Nov 22, 2011

As I continue my search to fix my DW, I find articles about castor angles, I do have adjustable upper and lower arms, so does anyone no what angle it should be set at with 6.5 in lift and how to set it????? Thanks

With that much lift, you probably want between 5-7* of castor. You need to adjust the length of the arms to set the angle - lengthening the lowers and shortening the uppers will increase the angle (bring the pinion down). Do a search and you will find instructions for where to measure the castor angle.

Found it, I also found lifts running 33s will usually like 6 deg. and 35s will usually like 5 deg.

Castor angle has nothing to do with how much lift you have. You want between 5-7* for any lift. You can adjust it up or town to make it handle differently.

What?? I am no expert but I certainly had to adjust my castor angle from 3 degrees or so to 6.5 when i went from a 4" to just over 6" in lift.

As far as running the same lift but simply changing from a 33" to a 35" tire SHOULD require NO castor adjustment.

I'll disagree because at some point you need to balance out the drivseshaft angle with the castor angle.

:doh:

What he's saying is that you WANT 5-7º of caster no matter what your lift height is. Of course your caster will change if you just lift it because of the control arm lengths/angles.

Obviously once you reach a certain lift height (hopefully never that high) you need to balance the pinion angle and caster angle which is solved by compromise or rotating the inner Cs.
