What caster angle do you want?

We're researching doing a JK version front housing with an optional caster angle. We don't really want to make this a 'custom' so we need to know if one specific angle will fill the need for most of the market.

What do you think? What caster angle would you like to have?

6* would be a good start point

I run 7*, but anything from 5.5* to 7.5* would work.

With the coil buckets at 0 degrees, 6 degrees positive caster with pinion rotated 3 degrees up.

This way, the caster can be dialed to 7 degrees if needed and the driveline angle will still be good to go (fast).

I wish this would have been a option in Feb/March, I remember asking about it. This works though.

Here is the axle that Phil is talking about installed on his Jeep. Unless you have custom super long control arms, I would only recommend a 3 degree pinion angle. The upper arms had to be lengthened somewhere between 11/16-13/16". The Tera Flex Upper arms have a ton of adjustment and worked perfectly for this application.

The stock Rubi front D44 seems to have about 0 degrees pinion with 4.5 degrees caster. With a TF 4" lift my front driveshaft is at about 9 degrees, so splitting the difference at 4.5 degrees on the pinion and 5+ degrees caster should be in the pocket. OTOH, for shorter lifts maybe the 3 degree suggestion would work better, and would work for most other suspensions.
