I was looking at the truck registry a while ago..On one of the pages they had a wheel
alignment chart.. one was what gm specs was and the other was what the a name that i forgot recommend.. i tried to find the registry again with no luck..
So i was wonding if any one had the specs for the alignment..
thanks in advance..

Don't know if anyone responded to you, but here is an old chart ala Brad Chase

Re: wheel alignment

I would suggest 6 to 7 deg caster, 1/8" toe in, -1/4 deg camber.

Both sides should be same caster otherwise vehicle will pull to side with more caster.

Just aligned mine after installing the JMS upper and lower control arms with the viking coilovers.
I set toe at 0. Camber at -1deg. can't remember what caster was. I believe it was between 5-6

I'll try these specs when I get mine aligned

Re: wheel alignment

Has anyone done the camber curve for the 4wd chassis? Is it as backward as the stock 2wd curve?

Re: wheel alignment

Now im re-reaging this post what are the pro and cons of the two differnt specs? in the upper part of this post? how would the truck drive?

Re: wheel alignment

Are those specs valid also when using ZR1 'vette 9.5" front wheels?

Re: wheel alignment

The wider the tire the more caster you want. Helps prevent the truck from wandering and tracking into ruts in the road made by semi's.

Re: wheel alignment

If you look at just about all new vehicles you will see caster in the 6-7 deg. range.

For example.

Alignment specs for the 2010 Camaro SS:

STOCK SPECIFICATIONS-STOCK SPRINGS

FRONT:

· CAMBER: 0° to -1.6°

· CASTER 6.70° - 7.10°


As mike said the wider the tire the more increasing caster will help you out. I run all of the trucks I align for customers in the 6-7 deg range. Every time the owners comment how well it handles over stock. Don't be afraid to put some caster in the vehicle and give it a shot. It can always be changed back.

Re: wheel alignment

Picture the front wheels on a shopping cart. When you push the cart forward the wheels spin around and "follow" the centerline of the wheel. This would be negative caster. If the wheels stayed forward and did not spin around this would be positive caster. Positive caster provides more directional stability. It is forcing the tire to control instead of giving it a preference to be controlled by the road. The down side of positive caster is heavier steering effort. In circle track cars we run staggered caster, which will cause the car to pull to one side. Obviously a circle track car is set to pull to the left.
