Hi everyone, I purchased a pair of SPC camber caster sleeves part number 23012. They are 1.5* sleeves that I want full caster. I have the slot towards the rear what would appear to be full 1.5* caster. How do I know I have the sleeves at 100% at full caster?

Also from SPC's website. Yup, slots toward the rear would be full caster.

Thanks for the templates, but I'm talking about what is there to index off of on the knuckle? In the picture above I put the split at the rear of the knuckle by eyeballing what I think is the rear of the knuckle. Maybe that's all I can do. I am going to get another alignment and see what has changed. It would be great if I would be able to turn the sleeve while on the alignment machine. I found that I have to have the ball joint loose to turn the sleeve.

1.5 is not truly enough, if you are like most, starting a 1 degree, you need 4-5 degrees total....

I'm at 1* now. This is on a stock suspension that I replaced the rear springs on 15 years ago. I added the 1.5* sleeves and I'm going to level the rake by removing the load spring. It is very high height compared to the front. I'm hoping to get to 4* caster.

The really old school way they use to bend the beam. Your next step would be to get 4 degree c-bushings unless you going to lift the thing.

4 or 8 degree bushing sends the front driveline angle completely in the wrong direction though...

I have run 4 degree bushings since 1978 I have 2.5 Inch lift and still running the factory driveshaft. good enough to get by all these years. the job is only intimidating because you haven't done it before. But you have to have Tall jack stands and jacks that can lift high enough. guys with a shop can do it quickly maybe a couple of hours if they have done it before. but you have to mark the c bushings so they put them right side up so there are no mistakes in assembly. many shops get them in wrong because they don't know better.
first job I did was change the bushings when I was 18 as the rubber ones spit out on their own.

I would opt for some bushings. I was playing with the idea of doing those sleeves. Even bought them. Once I started really looking at things I knew I had to do more....lots more.

I would say a couple hours for a shop max. or a casual Sunday at home and do it yourself. I have switched springs enough that I've got it down to a science for me at least.

You can do it man! Just get those 2 or 4 degree bushings and get it done.

So I finally got my alignment specs after installing the 1.5* camber caster sleeves. Probably pretty much a waste of time and money. I am going to tackle changing my c bushings to 4* in the near future.
I also got to believe something will have to be done with my steering box. Currently have a 6 turn rebuilt box from West Texas. I would like them to possibly convert to a 4 turn. I am not sure if they can do something to make the steering harder to turn.

Yep he math was there before you installed the sleeves, you original 1 degree plus 1.5 degrees sleeves were not going to get you there...

Not necessarily. You can clean up some of the lousy camber numbers using the adjustable sleeves.

Exactly - these sleeves shouldn't really have caster in their title. They're really only good for camber on our rigs and that's about all I've ever heard of anyone using them for. Most of us are looking for "big" caster number changes and these don't give them.

Agreed. You can't get there from here. I use those to level my hub when in the straight ahead position. They are good at fixing a tire leaning in or out. To fix pinion angle and caster you need to cut and rotate baby .
