Which is a better value RTE's Caster Corrected Swivel Ball Modification ($300) or DAP's Caster Correcting Poly Bushings ($160). 96 D1 w/2" RTE.
Caster Correction

If you've only got the 2" you should be fine without them, are you running into driveline issues after you put on the lift?
I think it would be a waste with that much lift. BUT if you do you need to let RTE do it. They did mine and it makes a big difference with the 5" lift. Didn't need it until i went from 3 to 5 though. Just remember the correction is for the exact lift you have so if you do it now it will have to be redone after you make any change thier after. Just go ahead and do the 5" a get it overwith . LOL (Yeah i went through the same thing)
It is not really a problem. I can live with it. Just one of those things that I thought I should do. I thought it may not be a bad idea for $160. Probably just a waste of money. Thanks for the input.
You seriously might want to look into other causes for the vibes or whatever is wrong. I have a 3 inch lift from RTE and they didn't need to do anything w/ the castor or those front radius arms or any of that stuff. The old stock front drive shaft was already loose and caused vibrations, but I had them put my spare stock drive shaft in and all the issues went away. It was a lot cheaper and the castor isn't really an issue for driving at all. I'd say it's better to look at other fixes/causes than to just throw money at it. That was RTEs philosophy and it saved me money.
:smilelol: youre in denial if you have a 3" lift on a D1 and think you dont have any castor issues....:smilelol:
It's my understanding that castor problems aren't usually a cause of vibes. Castor gives you the unicycle effect. Your steering gets a bit too quick. E.g. Unicycle vs a chopper.
Correcting castor can really improve the driveablity of a lifted rig. Even a 3" lift will have a noticeable improvment.

Ask Norman Hall or Keith Kreutzer about QT arms... They bent a pair practicing for the OBC.

Come on Paul, that is a cop out answer. While you might not be worried about caster on a trail only rig, pinion angle is a problem that is easily solved. We can take for granted that a trail only rig is going to have much bigger tires than stock thus requiring longer radius arms. If radius arms are going to be purchased or made, why not deal with the pinion angle?
RTE arms?When I did my 2in lift, I had the unicycle feeling, caster was off. After installing the arms it got much better. Then I installed two spring isolator, one on the top and one on the bottom to each spring which gave me an additional ? inches. That through off my caster again, now I got the unicycle feeling again, but not as bad.

That's fine for correcting the castor but what are you going to do about your pinion being nearly flat? Double DC driveshaft? We all know that those don't work for shit.
I don't know what's so hard about lifting these things properly. If you want to get your truck back to "stock" angles you need to correct the pinion angle with the arms and correct the castor with the swivels. DONE! Then go search for motor mounts or other dumb things that may cause vibes.
